Plan Quality Management - Tools and Techniques
Cost - Benefit Analysis
Cost of Quality : all costs included over the life of the product. Failure costs are often categorized into internal (found by the project) and external (found by the customer). Failure costs are also called costs of poor quality.
Cost of Conformance Cost of Non-Conformance
--------------------------------------------------------------------------------
Prevention Costs Internal failure costs
Training Rework
Document Process Scrap
Equipment
Time to do it right
Appraisal Costs External failure costs
Testing Liabilities
Destructive Testing Loss Warranties
Inspections Lost business
Seven Basic Quality Tools: Cause and effect diagrams aka fishbone or Ishikawa diagrams, Flow charts, Check sheets, Pareto diagram, Histograms, Control charts, Scatter diagram
A process is considered out of control when (1) a data point exceeds a control limit (2) seven consecutive plot points are above the mean or (3) seven consecutive plot points are below the mean.
Control charts may be also used to monitor cost and schedule variances, volume and frequency of scope changes or other management results to help determine if the project management processes are in control.
Scattered diagrams, plot ordered pairs (X,Y) and aka correlation charts. The direction of correlation may be proportional (positive correlation), inverse (negative correlation) or a pattern of correlation may not exist (zero correlation)
Benchmarking
Design of Experiments
Statistical Sampling
Additional Quality planning tools : Brainstorming, Force field analysis, Nominal group technique, Quality management and control tools
