Why would an organization want to engage in process reengineering? How can business processes be reengineered?

Organizations engage in process engineering in order to: centre control for the core processes with an identifiable group of people; focus the entire system on meeting customer needs and expectations; eliminate duplication of work and systems bottlenecks; reduce costs; and streamline operations efficiency. The reengineering of core business processes follows a six-step procedure. This procedure is:
Identify the core processes.
Map the core processes with respect to workflows.
Evaluate all tasks for the core processes.
Search for ways to eliminate unnecessary tasks or work.
Search for ways to eliminate delays, errors, and misunderstandings.
Search for efficiencies in how work is shared and transferred among people and departments.
