Overview

The Triptych Requirement Worksheet can be used to prioritize (or rank) Requirements by performing pair-wise comparisons of Items against each other in terms of relative importance. The theory behind this approach comes from the Analytical Hierarchy Process developed by Thomas Saaty in 1990.

Use in Product Development

The main advantage with Requirements worksheets is that it can be easily applied in a group setting and allows a team to come to a consensus on the relative priority of any set of Requirements.
