Concept

The option chosen in the initiation phase is fleshed out. The outcomes are drawn up in such detail that those involved in the project can plan, offer and realize the product or the IT system based on reliable foundations.
  1. The requirements are fleshed out and completed. The concept is designed on the basis of the chosen option. Feasibility is tested with prototypes, for example.
  2. The deployment concept is designed in preparation for deployment.
  3. Depending on the scenario, a test concept and migration concept are designed.
  4. In IT projects, the business organization concept, the system concept and the operating concept are designed. The system architecture decision is made.
  5. If a product or IT system is procured, procurement is carried out in this phase. The integration concept is then designed.
  6. The implementation release decision is made. The resources for the next phase are released based on the fleshed out project management plan and the offers available. The project and operational risks must be identified, analyzed and evaluated. Feasibility must be demonstrated.
At the end of the concept phase, a check is carried out to see whether it is wise to implement the project. Possible reasons for termination include economic inefficiency, excessive risks, infeasibility, lack of alignment with the objectives and strategies of the organization.
