STAG Software presented a webinar on Mar 14, 2013 on the topic - Agile Sutra "Do more by doing less, Prevent rather than detect". The webinar was hosted by T Ashok, Founder & CEO, STAG Software and Architect of HBT. The webinar outlines how HBT (Hypothesis Based Testing) can enable you to "do more by doing less" via enhanced defect prevention ability rather than find more.

2. Sutra
An user story is like a "sutra" - an
aphorism, that needs to be delved into
detail to understand its entirety.
And this is needed if you want to test well.

3. The Details of “How-To” ... the act of breaking the "big" into "small" (user stories) makes
one forget about who the end user is and what they value.
BIG Picture & Goal Setting
Hence it is necessary to think from the end user's perspective as
what they do and how the user story fits in the end user flow
and how non-functional attributes of the larger flow matter to
the user story.
