Davenport (1990) conducted a research and found that Information Technology (IT) can also have a stronger role in business process redesign. IT and BPR have a recursive relationship, (1)thinking about information technology should be in terms of how it supports new or redesign business process, rather than business functions or other organizational entities and (2)thinking about business process and process improvements should be in terms of the capabilities information technology can provide. Davenport (1990) suggests the five steps in process design (See Figure 3).
