Rescheduling in Project Management – Definition and Meaning
Rescheduling refers to the process of revising and adjusting the existing project plan (e.g., schedule, cost plan, resource plan) due to changes that have occurred, identified deviations from the original plan, or new information during the project lifecycle. It is used to correct the course of the project, respond to unforeseen events, or adapt the plan to changed conditions. Rescheduling is a central component of project control and involves redefining schedules, adjusting resource assignments, modifying project scope, or updating budgets.
Example, best practice, and further information on the term
In a software development project, for example, rescheduling the release date may become necessary if unexpectedly complex technical issues arise during development or if the customer requests a significant change in functionality. A proven best practice is to carry out rescheduling not arbitrarily, but as part of a controlled change management process, assessing the impact of changes and formally approving and communicating the updated plans. This is in line with the “Integrated Change Control” process in PMBOK and the agile principles of adaptability. Controlled rescheduling ensures that the project stays on track despite changes, or is deliberately realigned, and that all stakeholders are informed about the adjustments.
