1 2-1 Define Process The Quality Improvement Model Use SPC to Maintain Current Process Collect & Interpret Data Select Measures Define Process Is Process Capable ? Improve Process Capability Is Process Stable ? Investigate & Fix Special Causes No Yes No Yes Define Process Purpose: Communicate to an individual or team a clear understanding of the process under study. Establish improved and consistent process operations.

2 2-2 Define Process Process Components Suppliers Inputs Processes Outputs Customers l A process is any activity that converts l All processes involve Suppliers, Inputs, Outputs, and Customers

3 2-3 Define Process Defining Processes l Communicate to an individual or a team a clear understanding of the process under study. l Standardize process operations. l Identify and list Suppliers, Inputs, Outputs, and Customers. l Develop flow chart of the process steps. l Assure a common understanding of related procedures. l Verify practice vs. procedure. Why How

4 2-4 Define Process Process Standardization STANDARDIZATION is everyone following the procedures the same way. “It is neither possible nor necessary to standardize all the operations. However, crucial elements...should be measurable and standardized.” —Misaaki Imai KAIZEN l Are not the optimum perfection. l Are not necessarily the current best known methods. l Are the agreed-upon methods. These Procedures:

7 2-7 Define Process l What is the tool?  Graphical illustration of the process l What will the tool identify?  All value-added and non-value- added process steps  Input variables (X’s)  Output variables (Y’s)  Data collection points l When do you apply process mapping?  Always Detailed Process Maps

8 2-8 Define Process 1. Identify the process, its external inputs and customer outputs 2. Identify all steps in the process graphically 3. List output variables at each step 4. List input variables and classify process inputs as controlled or uncontrolled 5. Add process specifications for input variables Process Mapping Steps

9 2-9 Define Process Step 1: Identify the Process and Inputs/Outputs l We need to get a 50,000 ft. view of the process first  First identify the process in simple terms  Secondly we identify external inputs oIncoming information oRaw materials oPersonnel oEnergy requirements  Finally we identify the customer requirements (outputs) oIdentify the attributes of a correctly functioning product or service

29 2-29 Define Process The Catapult Process The Catapult process involves using a Catapult to hurl an object to a desired location. Some natural questions about the process are: l Who is the customer? l What does the customer want? l How should the Catapult be operated? l How do I know if I’m meeting customer needs?

30 2-30 Define Process Catapult 1.)Your Catapult Team should complete pages 1 through 4 of the blue “Catapult Process” handout. Limit yourselves to 30 minutes for this exercise. 2) Be ready to present your work. Note: Do Measure module first. Then do catapult for Define and Measure.
