Planning and executing an integrated program > Defining a program work breakdown structure
Define an integrated master plan
The Integrated Master Plan (IMP) is an event-based plan consisting of a hierarchy of program events. The IPP&E process supports Events Only or Event, Accomplishment, Criteria schemes defined on the plan object.
An IMP can be defined for a plan (common WBS plan, program, project, subproject). The common WBS plan is created and attached to the common WBS root.
For an IMP with a milestone breakdown scheme of Event, Accomplishment, Criteria, each event is supported by specific accomplishments. Each accomplishment is associated with specific criteria that must be satisfied for its completion. An event is complete when its supporting accomplishments are complete and when this is evidenced by the satisfaction of the criteria supporting each of those accomplishments.
The IMP is part of the contract and becomes the baseline execution plan for the program or project.
Example
A portion of an IMP for the Engineering, Manufacturing, and Design (EMD) Phase is as follows:
| IMP Activity # | Event | Accomplishment | Criteria | WBS Work Package that fulfills the criteria |
|---|---|---|---|---|
| A | Post Award Conference | A01 Management Planning Reviewed | A01a Program Organization Established | 1.3 |
| A01b Manpower Plan Established | 1.3 | |||
| A01c Initial Configuration Management Plan Completed | 1.6.2 | |||
| A01d Risk Management Process In-Place | 1.3 | |||
| A01e Program Schedule Reviewed | 1.3 | |||
| A02 Proposed Design Reviewed | A02a Proposed Design 3D Models Reviewed | 1.1 | ||
| A02b Proposed Design Simulations Reviewed | 1.1, 1.2 | |||
| A02c Proposed Design Manufacturability Assessed | 1.1.9 | |||
| A02d Proposed Design Supportability Assessed | 1.2 | |||
| B | Integrated Baseline Review | B01 Integrated Baseline Review Preparation Completed | B01a Baseline Schedule Released | 1.3 |
| B01b Baseline Work Packages Updated Based On Contract | 1.3 | |||
| B01c Baseline Initial Wave of Work Packages Released | 1.3 | |||
| B02 Integrated Baseline Review Completed | B02a Integrated Baseline Review Conducted | 1.3 | ||
| B02b Integrated Baseline Review Minutes Published | 1.3 | |||
| B02c Integrated Baseline Review Action Items Completed | 1.3 |
You can build a program IMP by creating a hierarchy of individual Event, Accomplishment, and Criteria elements as follows:
Procedure
Open the plan (program, project, or subproject) and click the IMP tab. Then, click Add Event from the work area toolbar of the Events section.
The Add Event panel is displayed.
Select Event from the list of types. Use the Filter box to find this type if it is not shown by default.
Enter details of the event and then click Add.
A new event is created.
Repeat steps 1-3 to create additional events.
To create an accomplishment for an event, select the event and then click Add in the Accomplishment section.
The Add panel is displayed.
Enter the details of the accomplishment in the Add panel and then click Add.
The new accomplishment is created.
Repeat steps 5 and 6 to create additional accomplishments.
To create criteria for an accomplishment, select the accomplishment and then click Add in the Criteria section.
The Add panel is displayed.
Enter the details of the criteria in the Add panel and then click Add.
The new criteria is created.
Repeat steps 8 and 9 to create additional criteria.
Note: WBS work packages can be related to criteria or events, depending on the IMP scheme (Event, Accomplishment, Criteria or Event only).
