The purpose of this article is to illustrate a tool I have developed and used to select and prioritize BPR projects. It is my experience that often, in an effort to build momentum on large-scale BPR endeavours, management focuses too long on easily achievable goals and puts off the tough but necessary projects. The Project Cost/Project Priority Matrix described here is a simple, but effective tool used to facilitate management and drive them toward more strategically significant projects. Business Process Reengineering (BPR) can be defined as the fundamental rethinking of business processes to achieve dramatic improvements in critical areas of performance. BPR focuses on identifying vastly superior ways to perform business processes and has been used successfully in almost every industry and government to increase productivity and decrease costs. Nevertheless, despite the successes BPR achieves, it remains a challenging undertaking. And the climactic time in any BPR effort is the implementation phase. You've done the analysis and laid out the blueprint for the new model, but now comes the crucial question, ‘What do we do first?’ In this paper, I will discuss the process of selecting and implementing the new (sometimes called ‘To-Be’) process model and review a tool that I have used successfully to facilitate the decision-making process.
