Figure 6-23. Control Schedule: Data Flow Diagram

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 (Section 4.6). Control Schedule, as a 

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

u

u

Determining the current status of the project schedule,

u

u

Influencing the factors that create schedule changes,

u

u

Reconsidering necessary schedule reserves,

u

u

Determining if the project schedule has changed, and

u

u

Managing the actual changes as they occur.

Part 1 - Guide

When an agile approach is used, Control Schedule is concerned with:

u

u

Determining the current status of the project schedule by comparing the total amount of work delivered and 

accepted against the estimates of work completed for the elapsed time cycle;

u

u

Conducting retrospectives (scheduled reviews to record lessons learned) for correcting processes and improving, 

if required;

u

u

Reprioritizing the remaining work plan (backlog);

u

u

Determining the rate at which the deliverables are produced, validated, and accepted (velocity) in the given time 

per iteration (agreed-upon work cycle duration, typically 2 weeks or 1 month);

u

u

Determining that the project schedule has changed; and

u

u

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.
