Overview > Lifecycle > Construction > Milestone

At the Initial Operational Capability Milestone, the product is ready to be handed over to the Transition Team. All functionality has been developed and all alpha testing (if any) has been completed. In addition to the software, a user manual has been developed, and there is a description of the current release.

Evaluation Criteria

The evaluation criteria for the construction phase involve the answers to these questions:

  • Is this product release stable and mature enough to be deployed in the user community?
  • Are all the stakeholders ready for the transition into the user community?
  • Are actual resource expenditures versus planned still acceptable?

Transition may have to be postponed by one release if the project fails to reach this milestone.
