III.            Six Sigma – Measure (30 Questions)

                              A.            Process analysis and documentation

                                                       1.            Process modeling
Develop and review process maps, written procedures, work instructions, flowcharts, etc. (Analyze)

                                                       2.            Process inputs and outputs
Identify process input variables and process output variables (SIPOC), and document their relationships through cause and effect diagrams, relational matrices, etc. (Analyze)

Process – a set of interrelated resources and activities, which transform inputs into outputs with the objective of adding value.

Process modeling – process maps, written procedures, work instructions, flow charts.

Process inputs and outputs

·          SIPOC – a high-level process map consisting of suppliers, inputs, process, outputs, customers.  As a high-level view, the process details should only contain 4-7 steps.

·          Relational matrices – a cause and effect matrix to aid in the prioritization of key process inputs. Shows the impact that process input variables have on process output variables.

·          Cause and Effect (Fishbone) diagrams – 4-M or Ishikawa diagram. Is divided into three parts: brainstorming, prioritization, and development of action plan. Is used to represent the relationship between some effect and all the possible causes influencing it.

·          4-M – manpower, material, method, machine

·          5-M - manpower, material, method, machine, measurement

·          5-M and E - manpower, material, method, machine, measurement, and environment
