In general, what is the purpose of the various activities that may be performed in BPR (e.g., outcome analysis, technology analysis, activity elimination)?
The analysis technique of BPA, BPI, or BPR is selected on the basis of several characteristics of the project. What are these characteristics and how do they influence the choice of analysis technique?
Explain the six criteria that distinguish the computing architecture options.
