The Engagement Manager should collect evidence, such as work products, performance measures, results and improvement information derived from the Quality Management stream and document the material in the summary in order to support the future use and improvement of the Quality Management process and associated assets. The information will be consolidated in the overall Service Close-Down Report, and will be made available to those who are (or who will be) planning and performing similar Service Engagements, as well as those who are locally responsible for continuous process improvement.
