The »V-Modell is designed as guidance for planning and executing development projects, taking into account the entire system life cycle. It defines the results to be achieved in a project and describes the actual approaches for developing these results. In addition the V-Modell specifies the responsibilities of each participant. Thus, the V-Modell describes in detail, "who" has to do "what" and "when" within a project. Other guidelines, e.g. ISO standards, are presently in use, but they are less concrete than the V-Modell because they, e.g., do not specify product templates.
These standardized, methodical guidelines permit a systematic execution even of complex and extensive projects. Thus, projects get more planable, traceable and lead to high-quality results with greater reliability, which is advantageous for acquirer and supplier.
The cooperation between acquirer and supplier is an essential factor of success. Thus, it is regulated by the V-Modell. The responsibilities of both sides are specified. Thus, the V-Modell standards are an important basis for contracts between acquirer and supplier. In addition, the V-Modell improves the comparability of »Offers.
Also small business enterprises profit from the V-Modell. The V-Modell provides them with standardized and well-tried templates for development and management processes. Thus, small business enterprises can systematize their processes with reasonable effort and thereby reliably achieve high-quality development results, as well.
Thus, the V-Modell can be used as basis for contracting, as process guidance and as basis of communication.
