Engineering Assignment Writing Secrets Revealed
Engineering students have likely heard the term "assignment" more times than they'd care to admit. But beyond the initial groan, these assignments serve a crucial purpose in your academic journey. They're not just about grades; they're your training ground for developing the critical skills you'll need to excel in the real world of engineering.
Types of Assignments for Engineering Students
Here are 5 most common types of engineering assignments that you may encounter in college:
Solving Problems
These assignments challenge students to apply engineering principles and scientific knowledge to analyze and solve real-world or hypothetical problems. They may involve calculations, simulations, or designing solutions that meet specific criteria.
Design Projects
In these assignments, students take on the role of engineers and design a product, system, or process. This could involve creating detailed drawings, using computer-aided design (CAD) software, or building a prototype.
Research and Analysis
Engineering is a research-driven field, and these assignments expose students to gathering data, conducting experiments, and analyzing results. Engineering students will face writing research papers, presenting findings, or drawing conclusions based on data.
Computer Simulations
Modern engineering heavily relies on computer modeling and simulation. These assignments involve using software to create virtual models of systems or processes to analyze their behavior and performance.
Technical Writing and Communication
Effective communication is essential for engineers. These assignments focus on developing writing skills, such as writing technical reports, proposals, or user manuals. Students may also be required to give presentations or participate in technical discussions.

Essential Engineering Assignment Writing Steps
An engineering assignment can feel like a daunting mountain to climb. But with a structured approach, you can conquer them and emerge a more adept engineer. Or, you can drop us a line, saying, ‘ write my assignment for me ,’ and keep the time required to fulfill the task to yourself.
1. Deep Dive into the Mission (Estimated Time: 15-30 minutes)
Don't just skim the instructions for your engineering assignments. Become an investigator, meticulously scrutinizing the details. Highlight key requirements, deadlines, and any grading rubrics provided.
These are the clues that lead to a successful resolution. Don't hesitate to ask your professor or teaching assistant to clarify any ambiguities. Remember, asking questions demonstrates initiative and helps avoid costly misunderstandings later.
Many professors provide grading rubrics – consider them your secret weapon. Analyze these rubrics carefully. They serve as a roadmap, ensuring your project addresses all the expected aspects and maximizes your potential score.
2. Break it Down and Conquer Piece by Piece (Estimated Time: 30-60 minutes)
Imagine that complex engineering assignment writing as a dense forest. Breaking it down into smaller, more manageable tasks is like chopping down individual trees. Each task becomes a stepping stone, leading you closer to the final solution.
Here's where prioritization comes in. Analyze the complexity and due dates of each task. Tackle the most challenging or time-sensitive tasks first. Think strategically about the sequence in which completing tasks will benefit you most.
Finally, create a to-do list that reflects your prioritized tasks. This is your action plan. Use whatever format suits you best – a physical list, a digital planner, or sticky notes on a wall. Visual tracking of your progress provides a sense of accomplishment and keeps you motivated.
3. Assemble Your Engineering Arsenal (Estimated Time: 1-2 hours)
Think of your knowledge and resources as your engineering arsenal. Dust off your course materials – textbooks and notes are valuable starting points. Review relevant sections to refresh your memory on foundational concepts and identify gaps in your understanding.
The online world can be your library. Explore reputable websites, scholarly databases, and even engineering forums (with a critical eye) to find additional resources. Look for data sets that might be relevant to your project or even case studies that showcase similar problems and resolutions.
Finally, identify any software or tools required for the engineering assignment and familiarize yourself with their capabilities. Can they be used to analyze data, create simulations, or generate visualizations? Understanding these tools empowers you to approach the problem from multiple angles.
4. Formulate a Strategic Battle Plan (Estimated Time: 30-60 minutes)
Every good engineer needs a plan. Now's the time to choose your weapon – a problem-solving approach that best suits the assignment. Brainstorming techniques, mind maps, or creating flowcharts can help organize your thought process and identify different avenues to explore.
Don't underestimate the power of a rough sketch! Sketching out initial ideas, potential findingd, or design layouts helps solidify your thought process and identify potential roadblocks early on. Visualizing your approach to engineering assignments can also spark new ideas and lead to creative solutions.
Create a rough action plan based on your chosen approach and initial sketches. This is your battle plan, outlining your steps to achieve your goal. Think logically about the sequence of tasks and how they build upon each other.
5. Tackle the Tasks with Focus and Discipline (Estimated Time: Ongoing)
Momentum is key. Start with less complex tasks to build confidence and get a sense of accomplishment. Completing smaller engineering assignment writing tasks provides a mental boost and motivates you to tackle bigger challenges.
Utilize your study schedule effectively. Allocate dedicated time blocks for focused work on specific tasks on your to-do list. This will help avoid procrastination and ensure steady progress towards your goal.
Try to minimize distractions. Silence notifications, put your phone away, and find a quiet study space to maintain concentration and maximize your productivity. Remember, focus, and discipline are essential tools in any engineering project.
6. Seek Allies and Guidance When Needed (Estimated Time: Variable)
Engineering is rarely a solitary pursuit. Don't be afraid to reach out to classmates for help on specific concepts or challenges. Explaining a concept to someone else can solidify your own understanding. Collaboration can also spark new ideas and lead to more creative solutions.
Tutors and learning centers offered by your university are valuable resources. They provide guidance and can clarify tricky concepts. Utilize these resources to bridge any knowledge gaps and ensure you're on the right track.
Finally, your professor is your powerhouse. Don't hesitate to seek assistance during office hours or via email for complex issues or roadblocks with an engineering assignment.
7. Test Your Solutions Like a Scientist (Estimated Time: Variable)
A good engineer never assumes their solution is perfect. Now comes the crucial step of testing your solutions thoroughly. Think of yourself as a scientist conducting an experiment.
Run simulations for your engineering assignments if applicable. For example, if you're designing a bridge, use simulation software to analyze its structural integrity under different load conditions. Analyze the results obtained and compare them to your expectations. Did your solution meet the design criteria? Are there any unexpected weaknesses or areas for improvement?
8. Refine and Polish Your Engineering Masterpiece (Estimated Time: Variable)
Based on your testing and self-evaluation, it's time to iterate on your approach and refine your solutions. Identify areas where your solutions might be weak or incomplete. Are there alternative approaches or additional calculations needed?
Embrace the iterative process – it's a core principle of engineering. Don't be afraid to go back and revise your initial ideas based on your findings. This might involve conducting further research, exploring different software functionalities, or even consulting with your professor or classmates.
Once your solutions are refined, it's time to draft, revise, and polish your report. Here, clarity and conciseness are key. Document your design process in a clear and organized manner, explaining the rationale behind your decisions.
Include relevant visuals like diagrams, simulations, or technical drawings to support your explanations. These visuals should be professional-looking and easy to understand.
Finally, proofread meticulously for any errors in grammar, spelling, punctuation , or calculations. A well-written and polished report demonstrates your professionalism and attention to detail.
9. Submit and Reflect on Your Engineering Journey (Estimated Time: 15-30 minutes)
Don't underestimate the importance of submitting your engineering assignment writing on time. Meet all deadlines and submit your assignment using the designated method.
But your journey doesn't end there. Take some time to reflect on your learning experience. Identify areas where you excelled and areas where you faced challenges. Did you learn any new software skills? Did you discover a more efficient problem-solving approach?
Reflecting on your experiences helps solidify your understanding and prepares you for future engineering challenges. This continuous learning process is essential for success in the field.
Assignment, novation and construction contracts - What is your objective?
Consider a not too hypothetical situation where the parties to a construction project (employer, contractor and sub-contractor) enter into a Deed of Assignment intending that the employer, having lost confidence in the contractor, would directly engage the sub-contractor to complete the sub-contract works. But what if no assignment has taken place? What are the terms of the contract under which the sub-contractor carries out the works for the employer?
Potential risks with assignment
In construction projects, main contractors often assign the benefit of their key sub-contracts to the employer in the event of contractor default and consequent termination of the main contract. The employer can then enforce the rights in the sub-contract against the sub-contractor, including rectification of the works and the performance of particular obligations.
However, there are potential risks associated with assignment in these situations as the Technology and Construction Court’s decision in Energy Works (Hull) Ltd v MW High Tech Projects UK Ltd demonstrated. We discussed this decision in Assigning a sub-contract on termination: which rights is the contractor giving up? In this case, the nature of the assignment meant that the main contractor could not pursue claims made by the employer against its sub-contractor under the sub-contract. This limited the main contractor’s ability to ‘pass on’ any liability it had under the main contract to the sub-contractor.
But what if the Deed of Assignment does not take effect as an assignment?
Assignment v novation
Both assignment and novation are forms of transferring an interest under a contract from one party to another. However, they are very different and in their effect. An assignment transfers the benefit of a contract from one party to another, but only the benefit, not the burden. In contrast, a novation will transfer both the benefit and the burden of a contract from one party to another. A novation creates a new contractual relationship - a ‘new’ contract is entered into.
Another key difference with novation is that the consent of all parties concerned must be obtained, which is why novation is almost always effected through a tripartite agreement. In the case of an assignment, it is not always necessary to obtain consent, subject to what the specific terms of the contract provide.
When deciding whether to assign or novate, parties should consider (i) whether there is in fact a burden to novate, (ii) whether the novatee will be willing to take on the burden, (iii) whether all parties will consent to the novation and indeed enter into the agreement. If there is no burden under the contract to transfer, then an assignment is likely to be the most appropriate way to transfer the interests.
Is the Deed for an assignment or a novation?
Although a document may be labelled a Deed of Assignment, if it has references to the transfer of ‘ responsibilities and obligations ’ and is a tripartite agreement these are characteristic of a novation as opposed to an assignment.
A key issue in such circumstances is to ascertain whether making use of the words ‘ assigning ’ and ‘ assignment ’ actually affects the characteristics of the document.
There has been some consideration of this characterisation issue by the courts. In the case of Burdana v Leeds Teaching Hospitals NHS Trust [2017] EWCA Civ 1980, by majority the Court of Appeal decided that on the facts of the case, although the Deed of Assignment in question referred to an ‘ assignment ’ of the benefit and burden, on proper analysis there was indeed a novation.
Furthermore, in the case of Langston Group Corporation v Cardiff City FC [2008] EWHC 535, Briggs J made it evident that even though the variation agreement in question did not use the word ‘ novation ’ and did not describe itself as such, the circumstances and effect of the agreement was indeed a novation and a new contract had been created.
It may be the case that even if a document does not describe itself as a novation, yet has the key characteristics of one, then as a matter of interpretation the courts would accept that the document takes effect as a novation.
Key characteristics of a novation
If entering into a document that purports to be a Deed of Assignment, tread carefully as it may well take effect as a novation, particularly if the following characteristics are present:
- It is a tripartite agreement;
- All the parties give their consent;
- The novator has been released from its obligations;
- There has been an acceptance of the terms of the novation on the part of the novatee and the substituted party; and
- There is a vesting of remedies.
What is your objective?
Although a document may well be labelled as an assignment, it may have the characteristics of and take effect as novation. Parties need to be cautious and consider what they want to achieve when assessing whether to assign rights or to novate them along with obligations.

Where to Put Dimensions
Introduction
One of the best ways to communicate one’s ideas is through some form of picture or drawing. This is especially true for the engineer. The purpose of this guide is to give you the basics of engineering sketching and drawing.
We will treat “sketching” and “drawing” as one. “Sketching” generally means freehand drawing. “Drawing” usually means using drawing instruments, from compasses to computers to bring precision to the drawings.
This is just an introduction. Don’t worry about understanding every detail right now - just get a general feel for the language of graphics.
We hope you like the object in Figure 1, because you’ll be seeing a lot of it. Before we get started on any technical drawings, let’s get a good look at this strange block from several angles.
Figure 1 - A Machined Block.
The representation of the object in figure 2 is called an isometric drawing. This is one of a family of three-dimensional views called pictorial drawings. In an isometric drawing, the object’s vertical lines are drawn vertically, and the horizontal lines in the width and depth planes are shown at 30 degrees to the horizontal. When drawn under these guidelines, the lines parallel to these three axes are at their true (scale) lengths. Lines that are not parallel to these axes will not be of their true length.
Figure 2 - An Isometric Drawing.
Any engineering drawing should show everything: a complete understanding of the object should be possible from the drawing. If the isometric drawing can show all details and all dimensions on one drawing, it is ideal. One can pack a great deal of information into an isometric drawing. However, if the object in figure 2 had a hole on the back side, it would not be visible using a single isometric drawing. In order to get a more complete view of the object, an orthographic projection may be used.
Orthographic or Multiview Drawing
Imagine that you have an object suspended by transparent threads inside a glass box, as in figure 3.
Figure 3 - The block suspended in a glass box.
Then draw the object on each of three faces as seen from that direction. Unfold the box (figure 4) and you have the three views. We call this an “orthographic” or “multiview” drawing.
Figure 4 - The creation of an orthographic multiview drawing.
Figure 5 - A multiview drawing and its explanation.
Which views should one choose for a multiview drawing? The views that reveal every detail about the object. Three views are not always necessary; we need only as many views as are required to describe the object fully. For example, some objects need only two views, while others need four. The circular object in figure 6 requires only two views.
Figure 6 - An object needing only two orthogonal views.
Figure 7 - An isometric view with dimensions.
We have “dimensioned” the object in the isometric drawing in figure 7. As a general guideline to dimensioning, try to think that you would make an object and dimension it in the most useful way. Put in exactly as many dimensions as are necessary for the craftsperson to make it -no more, no less. Do not put in redundant dimensions. Not only will these clutter the drawing, but if “tolerances” or accuracy levels have been included, the redundant dimensions often lead to conflicts when the tolerance allowances can be added in different ways.
Repeatedly measuring from one point to another will lead to inaccuracies. It is often better to measure from one end to various points. This gives the dimensions a reference standard. It is helpful to choose the placement of the dimension in the order in which a machinist would create the part. This convention may take some experience.
There are many times when the interior details of an object cannot be seen from the outside (figure 8).
Figure 8 - An isometric drawing that does not show all details.
We can get around this by pretending to cut the object on a plane and showing the “sectional view”. The sectional view is applicable to objects like engine blocks, where the interior details are intricate and would be very difficult to understand through the use of “hidden” lines (hidden lines are, by convention, dotted) on an orthographic or isometric drawing.
Imagine slicing the object in the middle (figure 9):
Figure 9 - “Sectioning” an object.
Figure 10 - Sectioning the object in figure 8.
Take away the front half (figure 10) and what you have is a full section view (figure 11).
Figure 11 - Sectioned isometric and orthogonal views.
The cross-section looks like figure 11 when it is viewed from straight ahead.
To prepare a drawing, one can use manual drafting instruments (figure 12) or computer-aided drafting or design, or CAD. The basic drawing standards and conventions are the same regardless of what design tool you use to make the drawings. In learning drafting, we will approach it from the perspective of manual drafting. If the drawing is made without either instruments or CAD, it is called a freehand sketch.
Figure 12 - Drawing Tools.
"Assembly" Drawings
An isometric view of an “assembled” pillow-block bearing system is shown in figure 13. It corresponds closely to what you actually see when viewing the object from a particular angle. We cannot tell what the inside of the part looks like from this view.
We can also show isometric views of the pillow-block being taken apart or “disassembled” (figure 14). This allows you to see the inner components of the bearing system. Isometric drawings can show overall arrangement clearly, but not the details and the dimensions.
Figure 13 - Pillow-block (Freehand sketch).
Figure 14 - Disassembled Pillow-block.
A cross-sectional view portrays a cut-away portion of the object and is another way to show hidden components in a device.
Imagine a plane that cuts vertically through the center of the pillow block as shown in figure 15. Then imagine removing the material from the front of this plane, as shown in figure 16.
Figure 15 - Pillow Block.
Figure 16 - Pillow Block.
This is how the remaining rear section would look. Diagonal lines (cross-hatches) show regions where materials have been cut by the cutting plane.
Figure 17 - Section “A-A”.
This cross-sectional view (section A-A, figure 17), one that is orthogonal to the viewing direction, shows the relationships of lengths and diameters better. These drawings are easier to make than isometric drawings. Seasoned engineers can interpret orthogonal drawings without needing an isometric drawing, but this takes a bit of practice.
The top “outside” view of the bearing is shown in figure 18. It is an orthogonal (perpendicular) projection. Notice the direction of the arrows for the “A-A” cutting plane.
Figure 18 - The top “outside” view of the bearing.
A half-section is a view of an object showing one-half of the view in section, as in figure 19 and 20.
Figure 19 - Full and sectioned isometric views.
Figure 20 - Front view and half section.
The diagonal lines on the section drawing are used to indicate the area that has been theoretically cut. These lines are called section lining or cross-hatching . The lines are thin and are usually drawn at a 45-degree angle to the major outline of the object. The spacing between lines should be uniform.
A second, rarer, use of cross-hatching is to indicate the material of the object. One form of cross-hatching may be used for cast iron, another for bronze, and so forth. More usually, the type of material is indicated elsewhere on the drawing, making the use of different types of cross-hatching unnecessary.
Figure 21 - Half section without hidden lines.
Usually hidden (dotted) lines are not used on the cross-section unless they are needed for dimensioning purposes. Also, some hidden lines on the non-sectioned part of the drawings are not needed (figure 12) since they become redundant information and may clutter the drawing.
Sectioning Objects with Holes, Ribs, Etc.
The cross-section on the right of figure 22 is technically correct. However, the convention in a drawing is to show the view on the left as the preferred method for sectioning this type of object.
Figure 22 - Cross section.
The purpose of dimensioning is to provide a clear and complete description of an object. A complete set of dimensions will permit only one interpretation needed to construct the part. Dimensioning should follow these guidelines.
- Accuracy: correct values must be given.
- Clearness: dimensions must be placed in appropriate positions.
- Completeness: nothing must be left out, and nothing duplicated.
- Readability: the appropriate line quality must be used for legibility.
The Basics: Definitions and Dimensions
The dimension line is a thin line, broken in the middle to allow the placement of the dimension value, with arrowheads at each end (figure 23).
Figure 23 - Dimensioned Drawing.
An arrowhead is approximately 3 mm long and 1 mm wide. That is, the length is roughly three times the width. An extension line extends a line on the object to the dimension line. The first dimension line should be approximately 12 mm (0.6 in) from the object. Extension lines begin 1.5 mm from the object and extend 3 mm from the last dimension line.
A leader is a thin line used to connect a dimension with a particular area (figure 24).
Figure 24 - Example drawing with a leader.
A leader may also be used to indicate a note or comment about a specific area. When there is limited space, a heavy black dot may be substituted for the arrows, as in figure 23. Also in this drawing, two holes are identical, allowing the “2x” notation to be used and the dimension to point to only one of the circles.
Where To Put Dimensions
The dimensions should be placed on the face that describes the feature most clearly. Examples of appropriate and inappropriate placing of dimensions are shown in figure 25.
Figure 25 - Example of appropriate and inappropriate dimensioning.
In order to get the feel of what dimensioning is all about, we can start with a simple rectangular block. With this simple object, only three dimensions are needed to describe it completely (figure 26). There is little choice on where to put its dimensions.
Figure 26 - Simple Object.
We have to make some choices when we dimension a block with a notch or cutout (figure 27). It is usually best to dimension from a common line or surface. This can be called the datum line of surface. This eliminates the addition of measurement or machining inaccuracies that would come from “chain” or “series” dimensioning. Notice how the dimensions originate on the datum surfaces. We chose one datum surface in figure 27, and another in figure 28. As long as we are consistent, it makes no difference. (We are just showing the top view).
Figure 27 - Surface datum example.
Figure 28 - Surface datum example.
In figure 29 we have shown a hole that we have chosen to dimension on the left side of the object. The Ø stands for “diameter”.
Figure 29 - Exampled of a dimensioned hole.
When the left side of the block is “radiuses” as in figure 30, we break our rule that we should not duplicate dimensions. The total length is known because the radius of the curve on the left side is given. Then, for clarity, we add the overall length of 60 and we note that it is a reference (REF) dimension. This means that it is not really required.
Figure 30 - Example of a directly dimensioned hole.
Somewhere on the paper, usually the bottom, there should be placed information on what measuring system is being used (e.g. inches and millimeters) and also the scale of the drawing.
Figure 31 - Example of a directly dimensioned hole.
This drawing is symmetric about the horizontal centerline. Centerlines (chain-dotted) are used for symmetric objects, and also for the center of circles and holes. We can dimension directly to the centerline, as in figure 31. In some cases this method can be clearer than just dimensioning between surfaces.

How Does a RACI Chart Help Project Managers?
Project managers use RACI charts to keep track of team roles and relay those responsibilities to the larger team. The matrix defines clear roles and responsibilities for individual team members across the various phases of the project, breaking the roles down into four types. Each letter of the project management acronym stands for a designation: those who are Responsible and Accountable for project deliverables, those who should be Consulted as work begins, and stakeholders who need to be Informed of ongoing progress, roadblocks, and updates.

RACI Matrix Definitions
Responsible.
The individual(s) with responsibility for the task or deliverable is typically responsible for developing and completing the project deliverables themselves. The responsible parties are typically hands-on team members who make direct contributions toward the completion of the project. The responsible team is comprised of the project’s “doers”, working hands-on to ensure that each deliverable is completed.
Some examples of responsible parties are:
- Project Managers
- Business Analysts
- Graphic Designers
- Copywriters
Accountable
Accountable parties ensure accountability to project deadlines, and ultimately, accountability to project completion. This group frequently also falls under the informed category.
Some examples of accountable parties are:
- Product Owners
- Signature Authorities
- Business Owners
- Key Stakeholders
Consulted individuals’ opinions are crucial, and their feedback needs to be considered at every step of the game. These individuals provide guidance that is often a prerequisite to other project tasks, for example, providing legal guidance on a project throughout the process. If you are working on new product development or expansion, this could essentially be the entire organization.
Some examples of consulted parties are:
- Legal Experts
- Information Security and Cybersecurity Experts
- Compliance Consultants
Informed persons are those that need to stay in the loop of communication throughout the project. These individuals do not have to be consulted or be a part of the decision-making, but they should be made aware of all project updates. Typically, this party are business owners or stakeholders that are more interested in viewing the project at a 30,000-foot view. Keep this group on your cc list for awareness of topics, decisions, and progress – that includes making them part of the initial project kickoff and project demos as optional attendees. This group often also falls under the accountable group.
Some examples of informed parties are:
- Project Committee Members
- External Stakeholders

Why Are RACI Roles Important?
The same way a requirements traceability matrix provides accountability to project requirements by mapping out the relationship between these requirements and the project work, RACI roles provide a sense of organization and clarity for teams that are looking to divide roles and keep team members accountable for their contributions. Considering that 27% of projects go over budget, for reasons like scope creep and lack of defined roles, RACI roles help position a project for success and avoid common pitfalls.
Moreover, RACI roles help ensure that communication between all roles is ongoing. When you consider that nearly half of all project spending is at risk of being wasted due to a lack of effective team-based communication, it becomes all that more important to prioritize. Ultimately, teams who prioritize communication and well-defined roles are better off, and RACI roles help teams achieve that goal faster – while providing accountability for each team member’s unique contributions to the success of the project.

How to Create a RACI Matrix
If you’re looking to implement a RACI matrix as part of your team’s project planning process, take these steps to create a RACI matrix.
Ensure that you have a thorough understanding of the project and its demands before outlining any further steps by communicating with key stakeholders and decision-makers.
Determine the list of key activities and deliverables from the director of program management or other leadership.
Determine who is needed to be a part of the project or initiative.
Determine the project roles and responsible job titles and persons for each activity and deliverable.
Hold review sessions with key members of the team for alignment, and if you haven’t already, host a kickoff meeting with the entirety of the team and key stakeholders to unveil the matrix, address questions, and more.
If the project has already started, it’s not too late to implement a RACI matrix.
- Outline the story. Using research from multiple sources, do a, b, c, and d.
- Utilize steps 2 and 3 (shown above). Ensure the right groups are assigned and engaged.
- Hold a review session. Ensure that the team acknowledges and discusses the plan and the roles assigned.

Examples of a RACI Matrix
As shown above, a RACI matrix helps break down what roles individuals will play as work is carried out and to what extent they will be involved in the project overall. The horizontal axis represents each person on the project team and the vertical axis represents each task.
Each square of the matrix represents an individual, a task, and that individual’s role within the project, either responsible, accountable, consulted, or informed. In this situation, for example, the project manager is accountable for accessing risk, defining performance requirements, creating designs, executing construction, and approving construction work. However, they are only informed about approving construction work and defining functional and aesthetic needs.

Who creates the raci matrix.
The RACI matrix — sometimes called RACI model, RACI diagram, or simply just RAC — is created by the project manager at the start of the project as a key part of establishing the initial human resources planning for the project. Because miscommunication is a common threat to any project, RACI charts are a great asset to teams dealing with any type of project, from very simple projects to extremely complex ones.
Common Mistakes When Creating a RACI Matrix
- Failure to plan ahead: Utilizing a RACI matrix should not be your first step in project planning. Having a fully assembled project team and at least a general idea of a task list and project plans is a better place to start before preparing a matrix.
- Working with too large a team: A RACI matrix is likely not the best bet for a large team, as it will make the matrix hard to understand and overly complex.
- Not communicating with the project team: A RACI matrix should help organize tasks and responsibilities that have already been introduced to the project team – no one likes to be blindsided. Be sure to host a kickoff meeting with the team first before creating a RACI matrix.
Frequently Asked Questions
Implementing a RACI matrix takes more than just a few emails and sporadic conversations – it takes consistent communication and planning. You should host a kickoff meeting to introduce the matrix to the team and make a plan to continue meeting at predetermined times throughout the project lifecycle.
Here are a few more tips to keep in mind as you implement your RACI matrix within the team dynamic:
- Get everyone prepared. Send the document around to the meeting distribution as read-ahead material, requesting feedback if there are any major concerns.
- Roll out each role for the team . During the meeting, conduct a review of the tasks and responsible parties. Do not rush through this review, but rather ensure enough time in your project kickoff for this important aspect. (Be certain to clarify the definitions of RACI to avoid ambiguity.)
- Consider changes and update accordingly. After the meeting, send out the notes documenting acceptance or updates to the RACI. In addition to sending out the notes, request any corrections within a reasonable yet defined timeframe. Clarify that if no changes are requested, each person is acknowledging their role and committing to the project tasks as outlined.
- Stay in touch. Consider a quick review with the entire team each quarter or every six months for longer projects to ensure it remains up-to-date and not simply another document in the repository but a relied-upon artifact.
As you implement the RACI matrix…
- Encourage teamwork and foster collaboration whenever possible.
- Don’t fear updates – make changes and adjustments as needed (but be sure to communicate those changes clearly to all parties).
- Earlier is better. Roll out your matrix plan to the team BEFORE you plan to implement it for the best results.
- Have a clear-cut understanding of the project scope and how each role connects to the overall project goal.
For “Responsible” Parties:
- Make sure your project’s definition of Responsible is clear on who holds the “decider” role for the project or project phase’s completion, and what the dimensions of that responsibility will be.
- Ensure that all parties are aware of their role and responsibilities within the matrix.
For “Accountable” Parties:
- When multiple Accountable team members must exist, use your definitions to make clear which individual is accountable for a given project element, and how that individual needs to interact with other Accountable team members.
- Ensure that there is only one “Accountable” party assigned per task.
- Be sure that the Accountable party has the authority and power to oversee the task as the accountable party.
For Consulted and Informed Parties:
- Consulted parties are often high-level decision-makers with heavy schedules. Make sure you’re clear on their availability ahead of time.
- Similar to Consulted parties, Informed parties are often less hands-on and have less understanding of day-to-day project operations. As the project goes on, make sure to keep detailed notes to keep the Informed party up-to-date on key information.
- Understand the ways that these parties like to communicate and create a plan to reach them early – whether that’s over phone calls, emails, video calls, or from within your project management system’s collaboration tools.
- Knowing the difference between who needs to be consulted versus informed can be a challenge if there is ambiguity about project roles. Consider what aspects of the project different team members need to know to do their jobs, and then bake those into your definitions.
RACI Matrix Pros & Cons
- Increased Engagement: RACI helps engage project participants in the project lifecycle.
- Enhanced Project Planning: Project managers make project planning more organized, efficient, and detailed.
- Identifiable Improvement Opportunities: Areas of improvement are more easily identified.
- Easier Collaboration: Use of a RACI matrix creates a clear path for leadership to sign off on project steps, as project documentation in the RACI model is heavily emphasized.
- Better Communication: Improves overall group communication as a whole.
- Group Accountability: Assists groups, especially larger project teams, stay connected and accountable to their roles and project goals
- Limitations on Role Scope: The RACI model does not provide details on role scope, especially for responsible parties. These gaps in detail also affect other team roles, for example, another gap in a RACI is the determination of who is responsible for verifier and signatory.
- Limits on Task Details and Scope: While a RACI matrix can provide an overview of who is responsible for different tasks, it will not state what needs to be done.
- Not Aligned to the Agile Methodology: Project managers using an agile methodology like scrum may find it redundant since accountability, ownership, and ongoing communication is built into the scrum framework (i.e., product owner, scrum master, and daily standups with the team). Additionally, agile focuses on team-based delivery and accountability, while the RACI framework and alternatives focus on individual responsibility and autonomous accountability.

Assignment Problem: Meaning, Methods and Variations | Operations Research
After reading this article you will learn about:- 1. Meaning of Assignment Problem 2. Definition of Assignment Problem 3. Mathematical Formulation 4. Hungarian Method 5. Variations.
Meaning of Assignment Problem:
An assignment problem is a particular case of transportation problem where the objective is to assign a number of resources to an equal number of activities so as to minimise total cost or maximize total profit of allocation.
The problem of assignment arises because available resources such as men, machines etc. have varying degrees of efficiency for performing different activities, therefore, cost, profit or loss of performing the different activities is different.
Thus, the problem is “How should the assignments be made so as to optimize the given objective”. Some of the problem where the assignment technique may be useful are assignment of workers to machines, salesman to different sales areas.
Definition of Assignment Problem:
ADVERTISEMENTS:
Suppose there are n jobs to be performed and n persons are available for doing these jobs. Assume that each person can do each job at a term, though with varying degree of efficiency, let c ij be the cost if the i-th person is assigned to the j-th job. The problem is to find an assignment (which job should be assigned to which person one on-one basis) So that the total cost of performing all jobs is minimum, problem of this kind are known as assignment problem.
The assignment problem can be stated in the form of n x n cost matrix C real members as given in the following table:

As Revised July 2019
By order of the United States District Court for the District of Columbia, former Section 11(c) of the NSPE Code of Ethics prohibiting competitive bidding, and all policy statements, opinions, rulings or other guidelines interpreting its scope, have been rescinded as unlawfully interfering with the legal right of engineers, protected under the antitrust laws, to provide price information to prospective clients; accordingly, nothing contained in the NSPE Code of Ethics, policy statements, opinions, rulings or other guidelines prohibits the submission of price quotations or competitive bids for engineering services at any time or in any amount.
Statement by NSPE Executive Committee
In order to correct misunderstandings which have been indicated in some instances since the issuance of the Supreme Court decision and the entry of the Final Judgment, it is noted that in its decision of April 25, 1978, the Supreme Court of the United States declared: "The Sherman Act does not require competitive bidding." It is further noted that as made clear in the Supreme Court decision:
- Engineers and firms may individually refuse to bid for engineering services.
- Clients are not required to seek bids for engineering services.
- Federal, state, and local laws governing procedures to procure engineering services are not affected, and remain in full force and effect.
- State societies and local chapters are free to actively and aggressively seek legislation for professional selection and negotiation procedures by public agencies.
- State registration board rules of professional conduct, including rules prohibiting competitive bidding for engineering services, are not affected and remain in full force and effect. State registration boards with authority to adopt rules of professional conduct may adopt rules governing procedures to obtain engineering services.
- As noted by the Supreme Court, "nothing in the judgment prevents NSPE and its members from attempting to influence governmental action . . ."
NOTE : In regard to the question of application of the Code to corporations vis-à-vis real persons, business form or type should not negate nor influence conformance of individuals to the Code. The Code deals with professional services, which services must be performed by real persons. Real persons in turn establish and implement policies within business structures. The Code is clearly written to apply to the Engineer, and it is incumbent on members of NSPE to endeavor to live up to its provisions. This applies to all pertinent sections of the Code.

Assignment, novation and construction contracts - What is your objective?
Consider a not too hypothetical situation where the parties to a construction project (employer, contractor and sub-contractor) enter into a Deed of Assignment intending that the employer, having lost confidence in the contractor, would directly engage the sub-contractor to complete the sub-contract works. But what if no assignment has taken place? What are the terms of the contract under which the sub-contractor carries out the works for the employer?
Potential risks with assignment
In construction projects, main contractors often assign the benefit of their key sub-contracts to the employer in the event of contractor default and consequent termination of the main contract. The employer can then enforce the rights in the sub-contract against the sub-contractor, including rectification of the works and the performance of particular obligations.
However, there are potential risks associated with assignment in these situations as the Technology and Construction Court’s decision in Energy Works (Hull) Ltd v MW High Tech Projects UK Ltd demonstrated. We discussed this decision in Assigning a sub-contract on termination: which rights is the contractor giving up? In this case, the nature of the assignment meant that the main contractor could not pursue claims made by the employer against its sub-contractor under the sub-contract. This limited the main contractor’s ability to ‘pass on’ any liability it had under the main contract to the sub-contractor.
But what if the Deed of Assignment does not take effect as an assignment?
Assignment v novation
Both assignment and novation are forms of transferring an interest under a contract from one party to another. However, they are very different and in their effect. An assignment transfers the benefit of a contract from one party to another, but only the benefit, not the burden. In contrast, a novation will transfer both the benefit and the burden of a contract from one party to another. A novation creates a new contractual relationship - a ‘new’ contract is entered into.
Another key difference with novation is that the consent of all parties concerned must be obtained, which is why novation is almost always effected through a tripartite agreement. In the case of an assignment, it is not always necessary to obtain consent, subject to what the specific terms of the contract provide.
When deciding whether to assign or novate, parties should consider (i) whether there is in fact a burden to novate, (ii) whether the novatee will be willing to take on the burden, (iii) whether all parties will consent to the novation and indeed enter into the agreement. If there is no burden under the contract to transfer, then an assignment is likely to be the most appropriate way to transfer the interests.
Is the Deed for an assignment or a novation?
Although a document may be labelled a Deed of Assignment, if it has references to the transfer of ‘ responsibilities and obligations ’ and is a tripartite agreement these are characteristic of a novation as opposed to an assignment.
A key issue in such circumstances is to ascertain whether making use of the words ‘ assigning ’ and ‘ assignment ’ actually affects the characteristics of the document.
There has been some consideration of this characterisation issue by the courts. In the case of Burdana v Leeds Teaching Hospitals NHS Trust [2017] EWCA Civ 1980, by majority the Court of Appeal decided that on the facts of the case, although the Deed of Assignment in question referred to an ‘ assignment ’ of the benefit and burden, on proper analysis there was indeed a novation.
Furthermore, in the case of Langston Group Corporation v Cardiff City FC [2008] EWHC 535, Briggs J made it evident that even though the variation agreement in question did not use the word ‘ novation ’ and did not describe itself as such, the circumstances and effect of the agreement was indeed a novation and a new contract had been created.
It may be the case that even if a document does not describe itself as a novation, yet has the key characteristics of one, then as a matter of interpretation the courts would accept that the document takes effect as a novation.
Key characteristics of a novation
If entering into a document that purports to be a Deed of Assignment, tread carefully as it may well take effect as a novation, particularly if the following characteristics are present:
- It is a tripartite agreement;
- All the parties give their consent;
- The novator has been released from its obligations;
- There has been an acceptance of the terms of the novation on the part of the novatee and the substituted party; and
- There is a vesting of remedies.
What is your objective?
Although a document may well be labelled as an assignment, it may have the characteristics of and take effect as novation. Parties need to be cautious and consider what they want to achieve when assessing whether to assign rights or to novate them along with obligations.
