The Scheduling Maturity Model was developed by a sub-group of the APM Planning, Monitoring and Control (PMC) SIG.

The Scheduling Maturity Model is intended to be applicable to schedules and scheduling processes for projects of all sizes in all industry sectors. It may be used in conjunction with the APM’s Earned Value Compass [1] on which it is based and with which it shares a common goal: the use of the model as a decision support tool. The model should be scaled and tailored to the project concerned. For example, small scale projects may not need large amounts of schedule detail or risk analysis, so high-level schedules (e.g. “level 1” or “level 2”) may be sufficient. Larger and more complex projects are likely to require lower-level scheduling (e.g. levels 3, 4 or 5).
