6 Part 6: V-Modell Reference Activities

6.2 Overview of the Activity Model of the V-Modell

In the V-Modell, activities will be hierarchically structured. The top level of the activity model will be formed by the »Disciplines. Disciplines will classify the activities by content aspects and will help to gain an overview of the activities of the V-Modell. In the V-Modell 13 disciplines will be defined. The disciplines may be subdivided into the three areas project (management), development and organisation. This classification is only used for the presentation within this chapter. The graphic notation for activities and disciplines used in the following figures will be explained in the part »Fundamentals of the V-Modell in the chapter »Process Modules.

In the V-Modell there will be a direct connection between activities and products, because each activity works on and finishes products. The grouping of products and activities, which is content-oriented, will be provided by disciplines, which include the products and the associated activities.


Figure 2: Project Disciplines

Figure 2 shows the disciplines from the area Project. The discipline »Planning and Control includes activities concerning the central project management functions. In this discipline, in particular the central project management control loop will be defined and described. Supporting activities for the generation of project reports and similar products will be combined in the discipline »Reporting. The functions belonging to the management disciplines configuration and change management and quality assurance will be described in the disciplines » Configuration and Change Management and » Evaluation. Activities concerning in particular the implementation of acquirer projects will be included in the discipline » Aquisition and Contracting. The same will be true for specific supplier activities in the discipline »Supply and Contracting.


Figure 3: Development Disciplines

Figure 3 shows the developement disciplines. Activities used to define requirements and to analyse various aspects of specific development disciplines will be brought together in the discipline » Requirements and Analyses. The discipline »System Specifications includes the procedure for the development of the technical requirements for and specifications of the system and its components. Activities that describe the implementation of the specifications to technical solutions and concepts, such as the preparation of the various architecture documents, will be brought together in the discipline »System Design. The activities for the integration and realisation of the system components will be included in the discipline » System Elements. Logistic support activities for the system will be listed in the disciplines »Logistic Conception on the concept side and »Logistic Elements for the realization and integration of logistic elements.


Figure 4: Organization Discipline

Figure 4 shows the organization discipline. The discipline »Process Improvement. The products of the various disciplines will be described in detail in chapter »Products . The following sections will provide a detailed summary of the activity structure of the V-Modell. In this context the activities will describe the methodical procedure for the generation of the products.
