12. Quality and Standards

13. Computer-Aided Software Engineering (CASE) Tools Automate many of the tasks required in a systems development effort and enforce adherence to the SDLC, thus instilling a high degree of rigor and standardization to the entire systems development process Upper-CASE tools - CASE packages that focus on activities associated with the early stages of systems development. Lower-CASE tools - focus on the later stages of systems development and are capable of automatically generating structured program code. Integrated-CASE tools - provide links between upper- and lower-CASE packages.
