Thanks for the info, Hans-Georg. I am looking for Business/IT-Alignment concepts. How many business engineers does a middle-size, large company need? How should business engineers interact with the management? How to choose topics and problems to solve ? etc.

Hi Ivan, probably is needed a context and business assumptions like the ones defined by organizational strategy. In the other hand, the number of engineers depends of the work to be done, and I think that BPM could give some orientations. Assuming that the work being done is represented by the business processes, and that's needed an as-is capacity of the actual process vs the objectives defined by top management. This articulation could lead to a definition of what could be done and how should be done. After this clarification of what is needed and resources available (engineers) I think that could be defined a number.

Topics that I found here are: Enterprise Architectures; Human Resources; Business Process Modeling and Business Process Design. Although could also be considered if existed current KPI in actual organizational processes.

I suggest to use a "value-driven" approach, identifying exactly the issues to be addressed through the business engineering approach and present then how "value-driven" business engineering can help here. I have done quite a bit of research in that area. You may want to check out my last book on Value-driven Business Process Management or the previous one of High Performance through Process Excellence.
