procedures that govern how resources are used to create products and services that meet the needs of particular customers or markets. As a structured ordering of work steps across time and place, a business process can be decomposed into specific activities, measured, modeled, and improved. It can also be completely redesigned or eliminated altogether. Re-engineering identifies, analyzes, and re-designs an organization's core business processes with the aim of achieving improvements in critical performance measures, such as cost, quality, service, and speed. Re-engineering recognizes that an organization's business processes are usually fragmented into sub-processes and tasks that are carried out by several specialized functional areas within the organization. Often, no one is responsible for the overall performance of the entire process. Re-engineering maintains that optimizing the performance of sub-processes can result in some benefits but cannot yield improvements if the process itself is fundamentally inefficient and outmoded. For that reason, re-engineering focuses on re-designing the process as a whole in order to achieve the greatest possible benefits to the organization and their customers. This drive for realizing improvements by fundamentally re-thinking how the organization's work should be done distinguishes the re-engineering from process improvement efforts that focus on functional or incremental improvement. History BPR began as a private sector technique to help organizations rethink how they do their work in order to improve customer service, cut operational costs, and become world-class competitors. A key stimulus for re-engineering has been the continuing development and deployment of information systems and networks. Organizations are becoming bolder in using this technology to support business processes, rather than refining current ways of doing work. Reengineering Work: Don't Automate, Obliterate, 1990 In 1990, Michael Hammer, a former professor of computer science at the Massachusetts Institute of Technology (MIT), published the article "Reengineering Work: Don't Automate, Obliterate" in the Harvard Business Review, in which he claimed that the major challenge for managers is to obliterate forms of work that do not add value, rather than using technology for automating it. This statement implicitly accused managers of having focused on the wrong issues, namely that technology in general, and more specifically information technology, has been used primarily for automating existing processes rather than using it as an enabler for making non-value adding work obsolete. Hammer's claim was simple: Most of the work being done does not add any value for customers, and this work should be removed, not accelerated
