How can you make sure that you have all of the activities and tasks of a new project accounted for in your project schedule before you send the final approved schedule to your project stakeholders?

As a project manager, you'll be responsible for developing and/or managing the project schedule. It's important to identify all of the project activities up front before you finalize the schedule. It can be difficult to add missed activities to your project schedule after you have the project schedule completed. Adding additional activities will most likely change the end date of your project or you'll have to shorten the time for some activities to make room for the new activities.
