During this phase, the program manager leads execution of contract award, vendor management, establishment of baselines, delivery of the business system, and risk management.  Meanwhile, the functional sponsor leads training and deployment.  The objective of this phase is to achieve organizational change through business process changes and delivery of the supporting business system, with minimal customization.


Phase Description:

Detailed fit-gap analysis follows solution selection based on the acquisition strategy.  Fit-gap analysis will be based on the known capabilities of the COTS/GOTS software in the selected business system solution.


Design specifications will reflect fit-gap analysis and prioritization of features to allow for cost and schedule trades within scope.


Development, delivery and support activities will be baselined and detailed in the implementation plan, expressed in terms of releases and deployments.

  • A limited deployment is any deployment before the Full Deployment ATP that provides a set of functionality to a set of users of the business system. The functional sponsor and program manager will recommend the functionality and number of users.  Limited deployments will be approved at a Limited Deployment ATP.
  • The MDA will require sufficient testing before Limited and Full Deployment ATPs. For business systems on the DOT&E Oversight List, DOT&E will approve all operational test plans, and an Initial Operational Test and Evaluation will be conducted before the Full Deployment ATP.
  • Full deployment is the delivery of full functionality planned to all planned users of the business system in accordance with the Full Deployment ATP.

The MDA will oversee establishment of cost, schedule and performance parameters for each release before development or delivery.
