Why do we need it?
IT ever more complex
Growthin CMM/CMMi & other models to
improve processes
Test Discipline maturing; what is there to assess
test & test-related quality processes in depth?
How do you assess the quality of the testingprocess that supposedly demonstrates quality?

Motivators
What are the testing capabilities internally & of external
suppliers? Ensure Regulatory & other Governance?Need objective robust assessment method, clearly
understood by all
Need to develop a structured test process improvement
framework
Want to identify improvement opportunities in an action
plan withrealistic timescales
Extend institutionalisation of good practices
Need to integrate seamlessly with project lifecycle…
often geographically challenged!

OtherContenders
Test Process Improvement (TPI) - continuous
model and flexible to organisation
Test Improvement Model (TIM) – Based on
CMM but not as extensive in KPAs nor as
detailed
CMM/CMMI –improving but still no depth in test
areas
SPICE – Doesn’t address in sufficient detail
TOM – good but protected

Why TMM?
We decided on TMM because:
We can useexperience and structure of CMM/CMMi
assessments and qualified CMM Assessors
TMM can be developed as a staged or continuous
assessment model
TMM can be used in isolation (of overall assessment
models)…In reality supports CMMi & other process maturity models, but
concentrates on testing!
Is robust and readily understood by all – results & certification
Robust, structured, common Process...
