Updating the schedule model requires knowing the actual performance to date.

Any change to the schedule baseline can only be approved through the Perform Integrated Change Control process.

Control Schedule, as a component of the Perform Integrated Change Control process, is concerned with:  

  • * Determining the current status of the project schedule, Influencing the factors that create schedule changes,  

  • * Reconsidering necessary schedule reserves,  

  • * Determining if the project schedule has changed, and  

  • * Managing the actual changes as they occur.  

  • When work is being contracted, regular and milestone status updates from contractors and suppliers are
  • a means of ensuring the work is progressing as agreed upon to ensure the schedule is under control.
  • Scheduled status reviews and walkthroughs should be done to ensure the contractor reports are accurate and complete.
