Business Process • a collection of activities that takes one or more kinds of inputs and creates an output that is of value to the customer. (Hammer&Champy, 1993) • Examples • procurement to shipment • concept to prototype • order to payment-
Sales Shipping Finance Production Warehouse Order Received Order Integration and Packing Credit Check Scheduling Assembly Order Delivery Order Fulfillment Process
Importance of Processes • Focus of reengineering is Processes • “It is not products but the processes that create products that brings companies long-term success. Good products don’t make winners; winners make good products(Hammer and Champy, “Reengineering the Corporation, HarperBusiness, 1993)

Process 1 • Batch size: 5 boats Step 1 Steps 5 & 6 Steps 3 & 4 Step 2
Process 2 • Batch size: 4 boats Step 1 Steps 5 & 6 Step 2 Steps 3 & 4
Team Activity • Summarize three changes you made and what they accomplished? • How does the design of the process affects customer’s purchase decision?
Competitive Priorities Cost Quality Time Flexibility
More Questions • How long was the average flow time (time from start to finish in the process)? • How does it compare with the time it would take to make one boat in an empty shop? • What is the importance of flow time? • How will you reduce the average flow time?
Flow Strategies • Flexible Flow- low volume, high variety • Line Flow- high volume, low variety

The way I see it process is the issue. But then the way I see it process is always the issue.
