This section identifies tools which may be used in the
Problem stage of the process
improvement framework for the
following activities:
- Mapping out the process or problem to understand it in detail and identify potential problem areas.
- Measuring the process to identify and verify problems.
- Prioritization and selection of specific problems that are to be addressed.
- Revising plans to reflect new knowledge.
- Mapping out the process or problem to understand it in detail and identify potential problem areas.
Map the process detail with IDEF0 or
Flowchart.
Use the Flow Process Chart for manual processes and the
String Diagram for processes that involve significant movement.
Break down products or problems with Value
Analysis.
Use a Matrix Diagram to investigate how requirements are met.
- Measuring the process to identify and verify problems.
Plot measurements in a Control Chart,
Line Graph or Bar
Chart. Investigate process distributions with a
Histogram or
Scatter Diagram and by measuring
Process Capability. Use
Design of Experiments (DOE) or a
Matrix Diagram for deeper investigation.
Find more information about the process with a
Survey,
Brainstorming or the
Nominal Group Technique. Collect data in a
Check Sheet or
Tables. Organize the information with the
Tree Diagram,
Affinity Diagram or Relationship
Diagram.
Use the Process Decision Program Chart (PDPC),
Failure Mode and Effects Analysis (FMEA) or
Fault Tree Analysis to identify potential problem areas.
- Prioritization and selection of specific problems that are to be addressed.
Organize measurements into priority order using the
Pareto Chart.
Agree on priorities in a group using the
Prioritization Matrix or
Voting.
Use the
Force-Field Diagram to resolve for-and-against decisions.
- Revising plans to reflect new knowledge.
Update plans using the same tools as in the
previous stage.
