After CS-443’s class this week, I decided to further investigate CMMI, Capability Maturity Model Integration, process model. I found testbytes’ article, “What is CMMI? (Capability Maturity Model Integration),” to be illuminating. This article gives an overview of CMMI and why it is used in software development.
At the end of the article is a link to another article by testbytes that caught my attention, “What is TMMI (Test Maturity Model Integration) in Software Testing?” TMMI is essentially CMMI with a focus on testing. While the two are similar, the focus of TMMI makes the implementation of CMMI on software testing smoother. TMMI has the same 5 stages of CMMI with some differences.
Level 1: Initial
- No test processes in place
- Failing to meet deadlines
Level 2: Managed
- Tests are planned and monitored
- Set test designs
Level 3: Defined
- All projects are tested from early stages onward
- Test reviews
Level 4: Measured
- Properly defined test strategies set in place from beginning of development process
- Projects tested at every stage to ensure bugless code
Level 5: Optimization
- Testing practices are structured
- All processes and outcomes are measured
TMMI is an interesting model that optimizes the testing process and while it is similar to CMMI, I’d still recommend a quick read through this of this article to others.
