Concepts

As a proponent of the Project Management Professional (PMP) exam, it’s crucial to understand the importance of scheduling based on methodology. The schedules aim to identify project tasks and their respective time frames, dependencies and resources. However, the scheduling isn’t a generic method; it’s pliable and should adapt to the project’s needs and methodologies applied. Below are some valuable insights that should guide you in creating a tailored schedule that aligns with the recommended methodologies.

Waterfall Methodology and Scheduling

The Waterfall methodology follows a linear approach where the project is partitioned into distinct stages, each dependent on the completion of the preceding stage. This methodology is known for its sequential process that includes stages such as requirements definition, design, implementation, testing, delivery, and maintenance.

When scheduling using the waterfall methodology, everything must be planned from the beginning, including every task and resource. Precedents and dependencies should be clear and logged in the schedule. The schedule follows a top-down approach, and it’s rigid due to a lack of flexibility in going back to a ‘completed’ phase. Therefore, accuracy and foresight in the initial planning phase are paramount.

For instance, consider a project to develop a software application. The stages could include requirement gathering, system design, implementation, testing, deployment, and maintenance. Each stage must be completed before the next starts, and therefore, the schedule must account for this sequential progression.

Agile Methodology and Scheduling

The Agile methodology, unlike the Waterfall approach, believes in flexibility and effective responses to changes. This methodology is continuous and iterative, focusing on incremental improvement in product quality, functionality and alignment to customer needs.

The schedule developed for Agile projects should be flexible, with priorities focused on the value-added elements. It predominantly follows a bottom-up approach and carries less weight on exact dates unlike the strict, sequential approach in waterfall methodology. The schedule comprises of short, repetitive work periods, known as Sprints or Iterations.

For instance, an e-commerce site project might initially prioritize developing a functioning shopping cart system over perfecting the site’s design aesthetics. The schedule for such a project would focus on achieving the ‘shopping cart’ functionality in the first Sprint, leaving room to adapt and modify future Sprints as the project evolves.

Hybrid Methodology and Scheduling

As the term suggests, Hybrid methodology incorporates elements of both Waterfall and Agile methodologies. This methodology ascertains that the project benefits from the structure of Waterfall methodology, and adaptability of Agile methodology.

Scheduling in a Hybrid environment includes an initial long-term plan from the Waterfall approach and several short cycles adapted from Agile. The initial schedule includes all the phases, while the subsequent schedule adapts to the project’s needs in a Sprint or Iteration.

For example, a project to create a new corporate website might initially follow a plan outlining the entire project’s flow (Waterfall method). Still, the task of creating individual site sections could take an Agile approach, offering adaptability based on feedback easier.

Conclusion

In conclusion, scheduling must not be generic but rather shaped by project needs and the methodology applied. Project managers have to understand the project’s nature, its requirements, potential changes, team structure, and client expectations when choosing a methodology and its corresponding schedule. Taking a mechanistic approach might jeopardize project success. Hence adapting a tailored schedule as per methodology contributes significantly to a project’s triumph.

Answer the Questions in Comment Section

True or False: The project schedule is always created after the project has started.

  • True
  • False

Answer: False

Explanation: The project schedule is a critical piece of the project plan, developed during the planning phase before actual work begins on the project.

Which of the following methodologies impact the way the project schedule is prepared

  • a) Agile
  • b) Scrum
  • c) Waterfall
  • d) All of the above

Answer: d) All of the above

Explanation: Each methodology has different ways and aspects of planning and scheduling. For example, Scrum has sprints, Agile is iterative and flexible, while Waterfall is linear and sequential.

True or False: In a project schedule, the critical path shows the longest stretch of dependent activities and any delay on them directly impacts the project completion.

  • True
  • False

Answer: True

Explanation: The critical path method is one of the most used techniques in creating project schedules, helping to identify the most important tasks that could impact the project timeline.

Which of the following tools can be used to represent a project schedule visually?

  • a) Gantt Chart
  • b) PESTEL Analysis
  • c) SWOT Analysis
  • d) Boston Matrix

Answer: a) Gantt Chart

Explanation: A Gantt chart is a bar chart that is used to represent project schedules visually, by showing when each task is scheduled to start and finish.

True or False: Agile methodology does not require project scheduling.

  • True
  • False

Answer: False

Explanation: Even though Agile is more flexible and adaptive than traditional methodologies, it still requires project scheduling. This is often done in the form of sprints.

True or False: The project schedule can never be changed once developed.

  • True
  • False

Answer: False

Explanation: Schedules should be updated and revised as necessary to reflect actual progress and any changes in scope or resources.

Which of the following is not an input to developing the project schedule?

  • a) Activity List
  • b) Risk Register
  • c) Project Budget
  • d) Stakeholder Register

Answer: d) Stakeholder Register

Explanation: While stakeholder input is important for most parts of project management, it’s not a direct input when developing the project schedule.

True or False: The critical chain method allows the project manager to schedule project activities based on resource availability.

  • True
  • False

Answer: True

Explanation: The critical chain method is a schedule network analysis technique that modifies the project schedule to account for resource availability and is beneficial in resource allocation.

The Work Breakdown Structure (WBS) is essential in project scheduling because:

  • a) It identifies all the deliverables in the project
  • b) It helps in cost estimation
  • c) It plots the project timeline
  • d) All of the above

Answer: a) It identifies all the deliverables in the project

Explanation: The WBS is a hierarchical decomposition of the total scope of work and it is crucial when preparing the project schedule as it identifies all the tasks that need to be planned for.

True or False: In Agile project management, the product backlog is equivalent to the project schedule.

  • True
  • False

Answer: False

Explanation: A product backlog is a prioritized list of features that could be developed, it’s an input to the project schedule but not equivalent.

Who is primarily responsible for developing the project schedule?

  • a) The Project Manager
  • b) The Stakeholder
  • c) The Project Team
  • d) The Sponsor

Answer: a) The Project Manager

Explanation: The project manager, with input from the project team, is primarily responsible for creating the project schedule.

True or False: Kanban is a project scheduling methodology.

  • True
  • False

Answer: True

Explanation: Kanban is a popular project management methodology that utilises a visual board (Kanban board) to manage the work schedule emphasizing continuous delivery.
