9.4    Concluding Remarks

An immediate remark is the need for modelers to be competent in using the techniques, or that at least a number of actors have applied the techniques previously. If not, the project group may use much time on discussing why and how to apply the technique and fail in developing the intended results.

Having applied a technique to previous problem situations may also increase the confidence in the efficiency and effectiveness of the technique (or alternatively, the lack of such, which is equally valuable). Hence, competent users may play the role of believers in the project, arguing that the chosen approach is fruitful. Believers may counter the tendency to delegate solution of the problem situation to a small group of actors prematurely, just to "remove" a problem.

Another remark is that the current pool of techniques can be changed or extended as deemed required by the project group. The decision on which techniques to include can be influenced by experience with techniques in practice. Practical application of Tema will probably lead to revisions of the approach. Practical experience may also lead to updates of .

Finally, having only a pool of techniques to aid in modeling and no predefined sequence may lead to inefficient use of time to decide what to do when. Tema does not prescribe any approach to keep the extent of discussions below an acceptable level, except stressing that the danger must be kept in mind.

Chapter closes part IV, being the answer to the should part of the main research question and RO2. The answer provided in chapter 8 was Tema. The answer given in chapter 9 concretizes a part of Tema, focusing on the activities of the enterprise modeling development phase, after preparations to modeling (stage 1) and before the preparations of exposed artifacts (stage 3).
