One study has determined that
85 percent of defects found in the Test phase were introduced in the Requirements
phase.
We admit, measurement programs can become onerous. The CMMI??™s response
to this criticism is that measurements should be tied to business objectives of the
organization. So, if you are highly driven by time-to-market, you would focus on
product defects and the scheduling effort. Decisions to release the product with an
???appropriate??? limit of defects would be made by senior management in order to
make the schedule date. That ???appropriate??? part should be determined based on
historical data (and analysis of that data and your measurement repository) for the
number of defects that can be released into the marketplace, and the types of defects
that can be released into the marketplace and still satisfy the customer and make
the product work.
