3 Part 3: V-Modell Reference Tailoring

3.1 Introduction

3.1.4 Notes on the Presentation in the V-Modell Reference

In the following paragraphs, the basic V-Modell concepts relevant for the V-Modell Reference Tailoring will be explained in detail.

The chapter »Project Types modifies the pictorial diagrams showing all process modules and decision gates of the V-Modell section »Fundamentals of the V-Modell in such a way that only the model elements applicable to the respective project type are depicted.

The chapter »Process Modules introduces the individual process modules of the V-Modell. The pictorial diagrams for the individual process modules follow the pattern shown in Figure 1. This figure is subdivided into two columns. The left column includes the »Roles, the right column comprises the »Discipline and »Work Product, and the right column includes the activity groups and activities relevant for the respective »Process Module. Activities are always assigned to the discipline of the work product, which is completed by the respective activity.

Elements defined in another process module are marked by a dashed edging. Initial products - i.e. products which must always be created once and only once - are marked by an "I" at the left edge of the product symbol. External products - i.e. products which are not generated within the scope of the »V-Modell Project - are marked by an "E". In addition, each product is assigned to one and only one responsible role by a connecting line. Roles which are not connected to a product contribute to the processing of one or more products of the respective process module without being responsible for it. The activity completing a certain product is also connected to the product by a connecting line.

The illustrations of the »Project Type Variant in chapter »Project Type Variants visualize the project flow through the individual »Decision Gates by means of arrows. Figure Figure 2 shows the semantics of the individual arrows.
