The option selected in the initiation phase is executed iteratively and incrementally. The project organization, including the development team, is established. The solution requirements are further divided, refined, and fleshed out. The requirements are updated, prioritized, and processed (developed, realized, and put into operation) in descending order of priority; priorities are updated continuously and adjusted according to project findings.

1. Based on the selected option and the initial status report from the study, situation analyses are carried out.
2. With the findings from the situation analyses, the requirements from the study are fleshed out, completed, and defined as prioritized initial solution requirements.
3. If the envisaged solution affects business processes or structures, the organizational requirements must be drawn up in every case.
4. If a solution is to be procured, the call for tenders is issued, the offers are evaluated, and the selected product or system is procured.
5. With each iteration, a further part of the solution - the increment - is created, which can be seamlessly connected to the already created scope of execution results.

Iterative and incremental execution :

1. Each individual solution requirement is continuously fleshed out, refined, completed, and divided and prioritized to such an extent that they can be processed in descending order of priority.
2. 1. The organization concept is drawn up and the successively emerging organization is realized and documented.
   2. The project, operational, and deployment risks are identified, analyzed, evaluated, and assessed. Feasibility is checked.
   3. The product is developed or adapted or the system is developed or parameterized.
   4. In parallel, the operating organization and all other outcomes of the remaining modules are successively developed, realized, and documented.
   5. For systems, the integration concept is designed and the decision on solution architecture is made.
   6. For systems, tests are designed and conducted, migration is prepared and carried out, and the system is integrated into the operating infrastructure.
   7. The deployment concept is designed and the preliminary acceptance, deployment measures such as user training etc., and the launch of operation are carried out.
   8. The organization, the relevant part of the solution (one or more increments), and the operation are activated.
3. During the initial period of operation until the acceptance of the part of the solution, the project supports problem analysis and resolution (after which the warranty begins, and with it regular operation).
4. If so defined in the project management plan, the decision on approval of the next release is made (decide on release).
5. The decision on closure phase release is made. The resources for the closure phase are released based on the updated project management plan.

After the completed launch of operation including the acceptance of the last release, the agile part of the project and the execution phase are completed; the development team is dissolved into the project organization.
