Acceptance Test Engineering Guide

Microsoft have released a draft version of a guide on Acceptance Testing. As well as covering the testing aspects of the acceptance process it covers the collection of data in order to making a decision during the acceptance activities. It also covers preparation for acceptance testing and the approaches to acceptance testing: specifically whether you do it in a separate stage (an acecptance testing phase) or throughout the full Software Development Lifecycle (SDLC). The latter they call Incremental Acceptance Testing.

You can download a copy of the Acceptance Test Engineering Guide and provide feedback on the same website in the discussion forum.
