The ACE Process was established to provide a structured approach to
developing estimates for teams that are striving to make Accurate and
Confident Estimates. It begins with preparation activities and
leveraging existing data prior to a planning session, describes specific
activities applied during the planning session, and defines key
finalization activities. It includes the introduction of some Agile
(Scrum) elements that have been proven to promote full participation at
all times using some enjoyable and effective techniques.
