>> 1) Test during the development phase (this is classic usability testing,
>>     testing prototypes at paper model, HTML model and working system
>>    stages)
>> 2) Test as a pilot before rollout. Test different versions

the

Every time you want to change something, including testing against the
current solution (known in DM speak as the banker)

Yup - test when you add a new tab.

It's an iterative, continuous cycle - Kaizan.
