Why is having a project timeline so important? Effective project scheduling can play a critical role in whether or not a project is a success or failure. A project timeline should be used no matter the size of the move. This timeline will help you set realistic time frames for when certain parts of the process need to be excuted by or how delays, if any, will affect your timing. The schedule can show you in sequence what items that should be done, what is next, and steps that have already been completed. This project timeline can also allow for easy status reports for additional team members or decision makers who may not be present day to day.
