Testing Levels (Test Process Maturity)
Understanding test process maturity levels from Level 0 to Level 4
Testing Levels (Test Process Maturity)
Test process maturity levels describe the evolution of an organization's testing capabilities. These levels, based on models like the Capability Maturity Model (CMM) and Test Process Improvement (TPI), help organizations assess and improve their testing practices.
Level 0: Ad-Hoc (No Formal Process)
What
Level 0 represents the absence of a formal testing process. Testing is performed in an unstructured, chaotic manner with no defined procedures, standards, or documentation. There is no systematic approach to quality assurance.
Who
- Individual developers or testers work independently
- No dedicated testing team or roles
- Testing is done by whoever is available, often as an afterthought
When
- Testing occurs sporadically, typically just before release
- No planned testing schedule or milestones
- Testing happens only when problems are discovered or when time permits
Characteristics
- No defined testing strategy or plan
- No documented test cases or procedures
- Testing is reactive rather than proactive
- No test environment management
- No configuration management for tests
- No measurement or tracking of testing activities
- High dependency on individual skills and knowledge
- Inconsistent testing practices across projects
Risks
- High defect rate in production
- Unpredictable quality outcomes
- No ability to estimate testing effort
- High cost of fixing defects late in development
- No learning or improvement from past projects
Deliverables
- None (no formal testing artifacts)
