Modify schedule, as needed, based on methodology

In project management, specifically in the pursuit of the Project Management Professional (PMP) certification, one key concept to understand is the flexibility to modify the project schedule as needed based on the project’s chosen methodology. This indicates the necessary adaptability of a project manager in adjusting timelines and sequencing activities based on the unique demands of the project methodology.

For example, methodologies such as Agile and Scrum assumes adaptability and changes within their framework. Agile promotes an iterative work style with continuous improvement, while Scrum provides a set of practices that control the work, with the flexibility to modify as required.

Understanding Project Schedules in Traditional and Agile Models

In a traditional model like Waterfall, the project schedule is often laid out sequentially from start to finish. Activities depend on the completion of the preceding tasks, creating a cascading effect.

Modifying a schedule in this structure would require reevaluating the entire sequence of activities, which can delay the project.

On the contrary, an Agile schedule is more flexible, promoting iterations, reviews and adaptations. The Work Breakdown Structure (WBS) supports the agility by dividing large tasks into smaller, more manageable ones. An Agile Sprint might look like this:

Changes in the Agile schedule are easier to implement as the project is built around adaptation and continuous improvement.

Role of a PMP in Modifying Schedules

As a PMP, your role in modifying schedules can vary greatly based on the methodology. In traditional models, it involves comprehensive planning, cautious execution, and strict control over changes. However, in Agile or Scrum, being a PMP means being an observer, a guide, and an enabler of the team’s self-governance. Simultaneously, you ensure that the team is able to respond effectively to required changes.

Examples of Schedule Changes

Consider a software development project run on Agile methodology. At the end of a 2-week sprint, the client requests changes in the functionality. Provided the team agrees to these changes after assessing the impact, the Project Manager can easily modify the schedule to accommodate this request in the next sprint. The schedule changes will likely affect prioritization and sequencing of tasks, but will not disrupt the project as a whole due to the Agile structure.

In contrast, imagine a construction project run on the Waterfall methodology. If changes are put forward late in the project, revising the schedule might require reverting back to the planning phase, delaying execution and consequently the project completion. This reiteration could have considerable impact on cost and resources.

In conclusion, the ability to modify the schedule as per methodology is not only valuable, but is crucial for Project Managers. Whether you’re adopting the iterative, adaptable Agile model or the linear, sequence-driven Waterfall model, the proficiency to tweak schedules during the project lifecycle can make a huge difference in project outcomes. As a PMP, becoming adept in scheduling and rescheduling based on your project’s methodology is undeniably a rewarding asset.
