There are dangers, however, of focusing too much on the technological part of a process. Information systems developers have a tendency to focus on what they call the logical aspects of processes. The logical aspects of a process are the essential characteristics of the process stripped of human idiosyncrasies and foibles. Humans are often seen to add unnecessary complexity and ambiguity. Inevitably, over concern with the logical aspects of processes results in processes that have little place for the human qua human .
Processes require robot like consistency and precision from their human components.
As a result these reengineered processes often do not exhibit the expected performance improvements and may even breakdown completely. We still have much to learn about reengineering business processes and the work that breathes life into these processes. What this section lacks in depth it makes up for both in the practicality of the advice it gives and the fact that it essentially hits all the high points. Benchmarking, in particular, has received relatively scant attention in the BPR literature. Managers have been exhorted to achieve quantum improvements in process performance but have been given little guidance as to what aspects of performance to focus on or even whether such improvements are possible to achieve.
