How might the scope of a project be altered if the Sequence Activities were altered or omitted?

A project would suffer greatly if one did not properly adhere to the sequence of activities.  Certain activities must be performed in a sequence due to the fact that some activities are dependent on the previous activity.  In other words, one needs to complete the dependent activities before beginning the next activity.  The key result of the Sequence Activities process is a network diagram that visualizes the project activities and shows the interrelationship of activities with arrows ((Master of Project Academy, 2022).

Can you give an example of a dependent activity?

Altering or omitting sequence activities can lead to significant project risks, including scope creep and timeline disruptions. If tasks are not performed in the correct order, dependencies may be overlooked, causing rework, inefficiencies, or even project failure. One example is the medical device development process—if design verification is skipped before validation, undetected design flaws may lead to costly delays when issues arise during validation testing.

A simple example of a dependent activity can be seen in cooking pasta. You must first boil water before adding the pasta—if you skip boiling the water, the pasta won’t cook properly. Similarly, in project management, some tasks must be completed before others can begin. If critical dependencies are ignored, it disrupts the workflow and may require backtracking, leading to wasted time and resources.

To prevent these issues, project managers use tools like the Critical Path Method (CPM) and Gantt charts to visualize dependencies and mitigate bottlenecks.

Cross-functional teams are essential to many projects, and omitting a sequence of activities can significantly impact their purpose. The purpose of these teams is to allocate project resource effectively and distribute project tasks efficiently. When a project's schedule is being developed, this is the time when cross-functional teams are considered so tasks may be designed in an order which benefits the setup. For example, if lab testing is critical to be completed in a certain week, the schedule will be aligned in a way which ensures this happens. By delaying, rushing, or doing tasks out of sequence, it could result in missed deadlines. Reordering sequences should not be detrimental to a project. This can lead to increased developmental costs if deadlines are missed and it also requires a project manager to update their documents to accommodate the reordering of tasks. Following the sequence of tasks as outlines within documentation set during the planning phase of a project ensures that cross-functional teams are working to their expectations and avoids unwanted consequences towards a project.

Altering or omitting the sequence of activities in a project can have significant consequences on its scope, timeline, and overall success. The sequence of activities defines the logical order in which tasks are performed, ensuring that dependencies are properly managed and the project progresses efficiently. When this sequence is disrupted, critical dependencies may be overlooked, leading to rework, inefficiencies, or missed deadlines. For example, in medical device development, skipping design verification before validation could allow undetected design flaws to surface later, resulting in costly delays or non-compliance with regulatory standards.

Additionally, cross-functional teams play a vital role in executing tasks in the proper sequence. Their schedules are often aligned with specific milestones, such as lab testing or clinical trials, to ensure timely completion. If the sequence is altered, it may lead to resource inefficiencies or misalignment with external stakeholders, increasing project costs and causing timeline overruns.

To prevent these issues, project managers rely on tools like the Critical Path Method (CPM) and Gantt charts to visualize task dependencies, optimize sequencing, and mitigate potential bottlenecks. Maintaining the planned sequence ensures that the project scope is preserved, risks are minimized, and deliverables are completed on time and within budget.

Altering or omitting the sequence of activities in a project can significantly impact its scope, timeline, and overall success. The sequence of activities ensures that tasks are performed in a logical order, managing dependencies and promoting efficient progress. Disrupting this sequence can lead to overlooked dependencies, rework, inefficiencies, or missed deadlines. For instance, in medical device development, skipping design verification before validation could result in undetected design flaws, causing costly delays or regulatory non-compliance. Cross-functional teams, whose schedules align with specific milestones, may face resource inefficiencies or misalignment with external stakeholders if the sequence is altered. Project managers use tools like the Critical Path Method (CPM) and Gantt charts to visualize task dependencies, optimize sequencing, and mitigate bottlenecks. Maintaining the planned sequence preserves the project scope, minimizes risks, and ensures timely, budget-compliant deliverables.

Altering or omitting sequence activities will lead to project inefficiencies, cost increases, and overdue completion.  Every activity is planned to come after the previous one so that there is unimpeded project execution. 

Disrupting the sequence may also affect resource allocation, delaying dependent tasks. Moreover, risks in the project can escalate, necessitating additional time for problem-solving and alterations. Software like Gantt charts help visualize dependencies and ensure activities are completed in the correct order, which can help in sequencing safeguards project scope and ensures efficient completion.
