Healthy baby at birth!

A large India Development Center (IDC) of a major consumer electronics& peripherals delivers 3-4 releases of their product every year. They had “birthing” problems – early stage defects were bogging them down. The root cause was identified as ineffective development testing. The team was mature, had good practices and were focused on “unit testing”. The big question that nobody wanted to ask was “what in the name of God is an Unit?”. This resulted in everyone in both early and late stage doing similar tests with poor results.

Applying STEM, we clearly identified the expectations of code from development and listed the types of defects that should not seep from development. Having setup clear cleanliness criteria, we had gotten around the “notion of unit”, and setup a goal focused development test practice. The test cases increased many-fold (this did not increase effort/time) and fault traceability made them purposeful.

The code coverage jumped from 65% to 90% with the remaining 10% identified as exception handling code that were hand-assessed. Now all early stage code were ‘completely assessed’. The RESULT – Defect escapes to QA team dropped by 30-40% and the specialist QA team could focus on their job and releases were made on time.

From premature babies needing incubators, we had transformed the organization to deliver bonny babies!
