COTS-Based Systems (CBS)


Reference SEI - Software Engineering Institute
The COTS-Based Systems (CBS) Initiative is focused on improving the technologies and practices used for assembling previously existing components (COTS and other non-developmental items) into large software systems, and migrating existing systems toward CBS approaches. The CBS approach changes the focus of software engineering from one of traditional system specification and construction to one requiring simultaneous consideration of the system context (system characteristics such as requirements, cost, schedule, operating and support environments), capabilities of products in the marketplace, and viable architectures and designs. The impact of this fundamental change is profound. Not only must engineering activities such as requirements specification change to support simultaneous consideration of system context, architecture and design, and the marketplace, but so must acquisition processes and contracting strategies. For example, integration contractors and commercial product vendors must be treated as partners and rewarded for identifying the best value to be achieved through the use of COTS products.
