How often do project managers need to update their project schedules?

Project managers need to update their project schedules regularly, depending on project demands, because the dynamic nature of projects often requires adjustments to timelines based on changes in scope, resource availability, risks, and stakeholder expectations. Frequent updates help ensure that the project stays on track and aligns with its goals.

In practice, this might mean revising the schedule after major milestones, when new deliverables are identified, or when unforeseen challenges arise. By keeping the schedule current, project managers can facilitate better communication with their teams and stakeholders, allowing for proactive problem solving and more effective resource management, ultimately leading to a higher likelihood of project success.

The other frequencies mentioned, such as weekly, monthly, or only at the start and end of the project, can be too rigid and may not adequately address the unique challenges that can arise at any point during the project lifecycle.
