FAQ

How do I determine the duration of a task?

Estimate the duration based on the actual work hours required, then add a percentage for potential revisions or unforeseen obstacles.

What should I do if a task falls behind schedule?

Reassess the project scope, reallocate resources from non-critical tasks, or adjust the end date of subsequent dependent tasks.

How often should this document be updated?

It is best practice to update the project schedule at least once per week or immediately following the completion of a major project milestone.
