In order to achieve a productive level of institutionalization of software reuse technology and the adoption of systematic reuse within NASA, the SORT Program is structured to operate over a multiphased period. Each phase is geared toward the accomplishment of specific goals which will ultimately lead to institutionalization and adoption of software reuse process and practices. It facilitates opportunites for these technologies and methodologies to be proven on NASA-specific projects.
Product lines highlight the commonality and variability inherent in a family of systems.
