Why can’t I buy an SCM tool?

Abstract

An organization that is evolving its software engineering environment needs an SCM tool that can evolve with the environment. SCM tools are available that can meet the tong term needs of such organizati0ns, but those tools are generally packaged in a way that, because of financial and managerial risks, makes them unacceptable for department level computing. SCM vendors are consequently excluded from a significant part of the SCM market, and users are forced to build custom SCM systems. The build-versus-buy dilemma could be resolved by a vendor-supplied SCM tool that is designed for incremental sale0 delivery, and operation, where later increments are differentiated by functionality beyond that of earlier increments. Such a toot might be composed of separate, interoperabte tool-sets.
