APM Project Fundamentals Qualification (PFQ) Practice Exam

An estimate's accuracy is expected to increase as a project progresses through its life cycle due to several factors. Early in a project, there is often less information available, leading to more uncertainty regarding costs, resources, or timelines. As the project continues, additional details are uncovered, and more accurate data can be collected, allowing for refined estimates. This means that as activities are completed and more information is understood, project managers are better equipped to make informed decisions, thus enhancing the precision of their forecasts.

The iterative nature of project management also facilitates this improvement in estimation accuracy. With regular monitoring and reviewing of progress, adjustments can be made in response to issues or changes, leading to more realistic estimates in subsequent phases.

In contrast, the other options suggest either a decrease in accuracy or stability of accuracy, which does not reflect the general understanding of project management principles, where ongoing refinement of estimates is expected. The final option implies that accuracy is unrelated to the project life cycle, which is inconsistent with best practices in project estimation. As such, the understanding that estimates should improve in accuracy over time is key to effective project management.
