- The Control Schedule Process is concerned with ensuring that the project schedule is monitored and changes to baseline happen in a controlled manner.
- The Control Schedule Process is also concerned with what has been accomplished so far and what is yet to be accomplished, ensuring that actuals collected in the schedule model are correct, ensuring critical path and buffers are under control.
- Incorporating changes approved by the CCB, consistent with the new baseline.
- In agile project methodology, control schedule is concerned with -

- Project Management Plan: Planning is iterative. Also, impacts due to other baselines or constraints are easier to track using the PM Plan.
- Project Schedule: An important input to check if the schedule is under control or the PM needs to influence factors leading to integrated change control.
- Schedule Data: While project schedule is the actual artefact, the schedule data makes possible to look at best and worst case scenarios. The data is needed mainly in case when schedule has to be controlled and to see the available options.
- Work Performance Data: As on date, how is work happening comes out of this metric while project schedule gives a holistic picture.
- Project calendars: In case if schedule is not under control , then there might be a need to plan for corrective action in which case, project calendars involving different work periods might be used.
- Organizational Process Assets: Lessons learnt, processes, policies and formats related to schedule control.

Tools & Techniques

- Performance reviews: How is the schedule performing and will perform - forecasts. Here are some of the review techniques:
-> Trend Analysis: Based on current performance, what will be the future and if everything will be under control at a later point.
-> Critical Path Method: What mileage has been covered in the critical path will give a better idea of the project health and corrective / preventive actions needed.
-> Critical Chain Method: What amount of buffer was allocated and what is used will give an idea of a need for corrective actions.
-> Earned Value Management: Schedule Variance (planned v/s actual), schedule performance indicator to check the health of the project and decide on corrective actions.
- Project Management Software: Softwares like Microsoft Project Plan are useful in looking and understanding the schedule data and finding variance / trends and then useful in finding if there will be a need for corrective action.
- Resource Optimization Techniques: How effectively resources can be used to get the schedule under control.
- Modeling Techniques: They are used to simulate what-if scenarios affecting the project objectives and seeing the impacts to the schedule.
- Leads and Lags: Leads and lags can facilitate paralleling of activities and thus help in gaining time-saving or schedule time gain or schedule catch-up.
- Schedule Compression: Adding more resources if schedule is lagging behind, in order to get schedule back on track.
- Scheduling Tool: Usually part of the project management software, the scheduling tool is used to build the network diagrams and do some base work that can be looked up and corrected if needed manually.


- Work Performance Information: The data is made concise good for reporting or to be fed in the change requests and then to be presented before the change control board.
- Change Requests: The document holding the changes and their impacts to different project objectives like cost and schedule impact. This becomes the input to the integrated change control process.
- Schedule Forecasts: These become inputs to the integrated change control process.
- Project management plan updates: Changes to Schedule baseline, once changes are approved by the change control board.
- Project Document Updates: Any updates to other documents like risk register or other relevant documents based on the change.
- Organizational Process Assets Update: Any new lessons learnt or process tailoring guidelines become part of the organizational process assets.
