What best practice should be followed to ensure a realistic project schedule?

To ensure a realistic project schedule, it is essential to document resource changes and their reasons. This practice allows project managers to have a clear understanding of how changes impact the project’s timeline, resource allocation, and overall workflow. By maintaining records of any alterations made to the project resources, including personnel changes, equipment availability, or shifts in task assignments, project managers can effectively assess the implications these changes have on the schedule.

This practice also aids in communication with stakeholders, as it provides transparency regarding why certain decisions were made and how they influence the project's trajectory. Furthermore, by understanding the reasons behind resource changes, project managers can make more informed decisions in the future, leading to more accurate scheduling and planning.

In contrast, while regularly updating the project scope can be important, it does not directly contribute to the establishment of a realistic schedule without the context of resource management. Limiting stakeholder input on changes may hinder effective collaboration and reduce the quality of the project schedule, as stakeholders often provide valuable insights that can help identify potential scheduling issues. Maintaining a consistent work time for all resources may not be feasible in practice due to differences in availability and productivity between individuals or teams, which can lead to unrealistic scheduling. Thus, documenting resource changes is key to ensuring a realistic project
