The product or system is implemented and tested. The necessary preparatory work is done to minimize the deployment risks.

1. The product or system is developed or, if procured, parameterized or adapted.
2. The organization is implemented.
3. In IT projects, the IT system is integrated into the operating infrastructure.
4. Preliminary acceptance is carried out.
5. The operating organization is implemented and the documentation is prepared.
6. Deployment is prepared on the basis of the deployment concept.
7. Depending on the scenario, tests are carried out and migration is prepared.
8. The deployment release decision is made (decide on phase release). It is based on the preliminary acceptance decision. The resources for the next phase are released based on the fleshed out project management plan.

At the end of the implementation phase, the deployment risks must be assessed and be acceptable. Otherwise, deployment cannot take place.
