QUESTION: 41

In general, why is it NOT a good idea to estimate the testing effort based only on a percentage of development effort? Identify THREE valid reasons.

The quality of the development estimate may be poor.
In general bottom-up estimation is always better than top-down estimation.
The percentage based technique only applies to the V life cycle model.
Using the same percentage every time does not address the level of risk of the application to be tested.
The maturity of the organization, e.g. the quality of the test basis, quality of development testing, configuration management, availability of test tools, also influence the effort needed for testing.
It builds on large set of historical data
The result is almost always a too low estimate for the required test effort

QUESTION: 45

Comparing TMMi and TPI, which is not a valid reason for choosing either TPI or TMMi?

If the scope of test performance improvement covers all test levels, TMMi is preferred since TPI focusses mainly on black-box testing.
If the organization is already applying CMMI, TMMi may be preferred since it has the same structure and uses the same terminology. TMMi addresses management commitment very strongly and is therefore more suitable to support a top-down improvement process.
TPI is much more a bottom-up model that is suitable for addressing test topics for a specific (test) project.
TMMi can only be used with the traditional V model,whereas TPI can be used with all types of software life cycles.
