Concept of Operations (ConOps) (glossary)
A comprehensive, integrated plan that identifies the acquisition approach and describes the business, technical, and support strategies that management will follow to manage program risks and meet program objectives. The Acquisition Strategy should define the relationship between the acquisition phases and work efforts, and key program events such as decision points, reviews, contract awards, test activities, production lot/delivery quantities, and operational deployment objectives.
