Evolutionary Development Model in the Initiation Phase

General
The life cycle approach to be adopted during the rest of the project should be considered in the Initiation phase. The phase-neutral themes (depiction of the life cycle approach with decision-making tools for supporting selection) contain an overview and a description of the models. A decision about the life cycle approach to be used during the further course of the project can be made as early as this phase if the preconditions are met.

Evolutionary development model

  • First initiation
    If a project is to be initiated for the first time, all activities and results must take the form set out here.
  • Further initiations
    If the decision to perform further initiations for individual versions is made on a project-specific basis or on the basis of the business process, certain deviations from the mandatory first initiation of the project may occur in the activities and mandatory results set out in the project or business process.

When does a new formal initiation need to be performed?
It can therefore be useful, before developing each version, to carry out a new formal initiation if there are long periods between successive versions or new impulses are generated from the business process, thereby enabling execution conditions, for example, to be checked again. However, every effort should be made to ensure the greatest possible continuity when developing a new version.
