Example Project 3


The Integrated Master Schedule (IMS) is a time-based schedule containing the networked, detailed tasks necessary to ensure successful program/contract execution. The IMS is traceable to the Integrated Master Plan (IMP), Work Breakdown Structure (WBS), Statement of Work (SOW), Contractor Performance Report (CPR) and Earn Value Management system (EVMS). The IMS is used to verify attainability contract objectives, to evaluate progress toward meeting program objectives, and to integrate the program schedule activities with all related components. The Program Manager (PM) develops an IMS on all cost or incentive contracts, subcontracts, Government Interagency Acquisition work agreements, and other agreements valued at or greater than $20 million. [1]


The IMS utilizes Critical Path network management techniques to optimize the relationship of critical activities. It uses the same (3) three; Events, Accomplishments, and Criteria to show network relationships; as IMP.

The four (4) steps to developing an IMS: [1]

  1. Develop the Integrated Master Plan (IMP)
  2. Develop the Work Breakdown Structure (WBS) based on the overall system’s Physical Architecture identifying all of the major systems and subsystems down to a configuration item level (CI)
  3. Defined configuration item level in terms of calendar time and resources to complete
  4. Place developed system time and resources into scheduling software (see Schedule Development)


Date Item Description (DID) DI-MGMT-81861 “Integrated Program Management Report (IPMR)” is used to obtain the IMS. The contracting officer and contractor should negotiate reporting provisions in the contract, including the level of detail, submission dates, and frequency of the schedule risk analysis. The IMS is not normally considered a contractual document. [1]
