5 Part 5: V-Modell Reference Work Products

5.2 Overview of the Product Model of the V-Modell

5.2.1 Disciplines

Products are structured hierarchically in the V-Modell. The disciplines are the highest level of the product model. They categorize products in accordance with their contents and are useful for providing a survey of the V-Modell products. The V-Modell defines various disciplines, which can be subdivided into three categories - project (management), development, and organization. This classification is only used for the presentation within this chapter.

Figure 3: Project Disciplines

Figure 3 shows the project disciplines. The discipline »Planning and Control includes the central »Project Management products, like »Project Manual, »QA Manual and »Project Plan. Project reports and similar products supporting the project management are summarized in the discipline »Reporting. The products of the management disciplines Configuration and Change Management and Quality Assurance are summarized in the disciplines »Configuration and Change Management and »Evaluation. Specific products for the execution of acquirer projects are included in the discipline » Acquisition and Contracting, specific products for the supplier in the discipline »Supply and Contracting. Frequently, acquirer products have counterparts on the side of the supplier, and vice versa. An acquirer/supplier interface, which is modeled explicitly in the V-Modell (see »Generative Product Dependencies), is based primarily on products of these two disciplines.

Figure 4: Development Disciplines

Figure 4 shows the development disciplines. Products describing the functional requirements and analyses for specific development disciplines are summarized in the discipline »Requirements and Analyses. The discipline »System Specifications includes the technical requirements and specifications for the system and its components. Products describing the implementation of specifications in technical solutions and concepts - like the different architecture documents - are summarized in the discipline »System Design. The realized system components and the system itself are included in the discipline »System Elements. Products for the logistic support of the developed system are listed in the discipline »Logistic Conception for the concept documents and in the discipline »Logistic Elements for the realized logistic elements.

Figure 5: Organization Disciplines

Figure 5 shows the organization disciplines. The discipline »Process Improvement includes products used for the introduction and maintenance of an organization-specific process model.

The products of the various disciplines and the disciplines themselves will be described in detail in the chapter »Products. The following paragraphs provide a survey of the different connections between the products. In the V-Modell, these connections are modeled explicitly as product dependencies.
