Component-Based Architecture (CBA) is a lifecycle approach to architecting software solutions from components. It produces applications that are very flexible because of their component "plug and play" nature. By modeling the business from a services perspective, we produce a target architecture consisting of highly reusable components. This approach is key to implementing applications (and modernizing legacy applications) that are able to support, rather than inhibit, business change. Reference/URL Context Definition 1    (2V1D)

Component Based Architecture. Under development by the FEA-PMO. By defining and publishing these building blocks and groups of building blocks in the Federal Enterprise Architecture (FEA), OMB has, as a primary goal, the reuse of components to increase efficiency and effectiveness and reduce costs. A key information-sharing item to facilitate adoption of the CBA will the Component Registry / Repository. See Component Registry / Repository.    (2V1G)
