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
