9.3    Some Dependencies Between Techniques

A summary of the techniques is provided in in terms of appropriate input and outcome. In addition, a column indicating the role of the technique as a part of Tema is introduced, indicating whether the technique supports sense-making (S), representation (R), or manifestation (M) of enterprise models.

Table 9.1: Summary of proposed elements in the Tema pool of techniques

Recall that the pool of techniques is a part of the development phase of Tema. Hence, all techniques concern activities concerned with development of models, and the question of model distribution is not discussed. Another observation from is that the techniques mostly support the sense-making part of enterprise modeling and less representation or manifestation. This is consistent with the intention of Tema.

When to use each technique must be decided from the qualities of the technique and the perceived needs in a problem situation. Consequently, strict rules for usage of the techniques are not given, although a few guidelines are summarized in figure 9.9.

There are two symbols used in :

 
From , the output from brainstorming can be input to term characterization. An OPPO assessment can be applied to all the techniques by describing the objective, product, process and organization of the technique.

The assessments made in are intended as indications of some possible combinations of techniques, and are explicitly not meant as authoritative rules. Some prominent observations include: Otherwise, the techniques may be used freely depending on the competence and preferences of the modelers.
