Exam PMP topic 1 question 652 discussion

The question is not about estimations but scheduling. Iterative scheduling is best for unknown factors.

In an agile software development project with various unknowns, an iterative scheduling approach is often suitable. This method allows the project team to work in short iterations, commonly referred to as sprints in agile, where they can adapt to changing requirements and address uncertainties as they arise. The iterative approach is flexible and allows for continuous improvement based on feedback received during each iteration.

When facing a software development project with various unknowns and using an agile approach, it can be challenging to create a detailed project schedule in advance. Agile projects often prioritize flexibility and adaptability over detailed upfront planning. Therefore, the project manager should use a scheduling approach that aligns with agile principles. The most appropriate method in this context is: C. Iterative scheduling. Iterative scheduling is well-suited for agile projects because it allows for flexibility and adaptation as the project progresses. In an iterative approach, the project is divided into smaller iterations or time-boxed cycles, where the team works on a subset of requirements or features. After each iteration, the team reviews the progress, gathers feedback, and adjusts the project plan accordingly.

C. Iterative scheduling

Iterative scheduling is also very powerful. When incorporated appropriately in an adaptive environment, the project manager and team will be more likely to: be more flexible with timelines, save time within the project timeline, save resources for only necessary work, improve project team and stakeholder communications, and boost team productivity. https://projectmanagementacademy.net/resources/blog/iterative-vs-on-demand-scheduling/#:~:text=of%20each%20iteration.-,What%20is%20Iterative%20Scheduling%3F,there%20are%20last%2Dminute%20changes.

Should be C. Iterative scheduling is a fundamental part of the Agile methodolog.

Analogous, Three-point and Parametric is for estimations

For Iterative, only approach is "Iterative". Rest all options belong to Predictive

For Agile project, iterative scheduling is better. Also the question is about scheduling as a whole and not estimation.

PMBOK 6.2.2.3 ROLLING WAVE PLANNING Rolling wave planning is an iterative planning technique in which the work to be accomplished in the near term is planned in detail, while work further in the future is planned at a higher level. It is a form of progressive elaboration applicable to work packages, planning packages, and release planning when using an agile or waterfall approach. Therefore, work can exist at various levels of detail depending on where it is in the project life cycle. During early strategic planning when information is less defined, work packages may be decomposed to the known level of detail. As more is known about the upcoming events in the near term, work packages can be decomposed into activities.

When the requirements are not clear or unknown and it is a software project, agile is advised. check this PMI for reference on atopic tilted 'when requirements are unclear'

Iterative scheduling is driven by project management methods in which tasks are divided into a series of mini-projects called iterations. Three-point estimating is a management technique to determine the probable outcomes of future events based on available information. The term refers to the three-points it measures: the best-case estimate, the most likely estimate, and the worst-case estimate.

Three-point scheduling is a method that uses optimistic, pessimistic, and most likely estimates to determine a range of possible durations for each activity. This method is particularly useful when there are unknowns in the project that make it difficult to estimate the time required for each task. By using a range of estimates, the project manager can better account for uncertainties in the schedule and develop a more realistic plan.

PERT for unknowns

A Three-Point Estimating Technique: PERT -The Program Evaluation and Review Technique (PERT) is used to find the estimated time for activities to be completed when there are many unknown factors.
