Six Sigma Project Test Plan
This is a practical guide to building a test plan for a six sigma project project — the approach, scope and schedule for testing the deliverables, adapted to the realities of reducing defects and variation in a process.
What a Test Plan is
A test plan is the approach, scope and schedule for testing the deliverables. For the full concept and how it works in general, see Test Plan. On a six sigma project project it plays the same role, tuned to this kind of work.
Why it matters for a Six Sigma Project project
Six Sigma Project projects live or die on reducing defects and variation in a process. A well-built test plan gives the team a shared, explicit reference for exactly that — reducing ambiguity, aligning stakeholders, and making problems visible early enough to act. Skipping it, or doing it generically, is how six sigma project projects drift into avoidable delay and cost.
What to include
- Test scope and objectives
- Test cases/scenarios
- Environments
- Entry/exit criteria
- Defect management
Six Sigma Project-specific considerations
Tailor the test plan to the risks that most often derail six sigma project projects:
- Data availability
- Root-cause complexity
- Sustaining control
Example
On a real six sigma project project, the test plan would be shaped by reducing defects and variation in a process. In particular, it should explicitly account for the project’s biggest risks — data availability, root-cause complexity, sustaining control — rather than treating them as afterthoughts.
