Here are the techniques for planning quality.
- Cost Benefit Analysis – The benefit achieved by spending on quality.
- Cost Of Quality – The total cost incurred by not preventing failures. This include rework by project team, warranty, lost business etc.
- Control Charts – helps identify if process is within limits or has predictable issues. Specifications limits, Control Limits and mean is drawn. If point above or below control limits or if there are 7 consecutive points above or below mean, it is investigated further for prevention steps. Control limits are generally +/- 3σ.
- Benchmarking – looking at other projects for best practices.
- Design of Experiment – Statistical method of Finding optimized number and type of tests. Variables are systematically changed rather than one at a time.
- Statistical Sampling – Randomly choosing samples for testing.
- Flow-charting – A quality process chart showing when to perform test and what to do on outcomes etc.
- Quality Management Practices – such as CMMI, Six Sigma etc.
- Other techniques such as Brainstorming, Affinity Diagram, Force Field Analysis, Nominal Group techniques, matrix diagram, prioritization matrix.
