Reengineering is the fundamental rethinking and radical redesign of business processes to achieve dramatic… — Michael Hammer

A business process is a collection of activities that takes one or more kinds of input and creates an output that is of value to the customer. A business process has a goal and is affected by events occurring in the external world or in other processes.

Sadly, we must report that despite the success stories described in previous chapters, many companies that begin reengineering don’t succeed at it... Our unscientific estimate is that as many as 50 to 70 percent of the organizations that undertake a reengineering effort do not achieve the dramatic results they intended.

Observing and performing the process is the best way to develop insight into it. However, the team must be vigilant about avoiding the temptation to overstudy. The goal must be to move quickly to redesign. Before concluding we should comment on another tool that is available to reengineering teams, namely benchmarking. Essentially, benchmarking means looking for the companies that are doing something best and learning how they do it in order to emulate them... Used this way, benchmarking is just a tool for catching up, not for jumping way ahead. Benchmarking can, however, spark ideas in the team—especially if teams use as their benchmarks companies from outside their own industries.
