Quality Attribute Workshop Experiences and Reflections

Abstract

This presentation describes experiences and reflections we have made from performing Quality Attribute Workshops (QAWs) at three different business units within ABB. All three systems are industrial software-intensive systems. The cases we report on include both evolutionary development of a product and revolutionary development.

The findings are mainly related to the voting process, in which scenarios are prioritized, but can also relate to the scenario-generation process. Moreover, we have made observations concerning maturity of the organization in which the QAW is performed, the dynamics in the group of participants and management’s perception and acceptance of the outcome from the QAW. Our conclusion is that the different objectives and different set-ups of the QAW participants and their relation to each other have a direct relation to the outcome of the QAW voting procedure and to the management’s acceptance of the outcome.
