Client-centric CASE

Since the early 1980s, AT&T ISTEL has been operating a business and software process re-engineering programme. The paper presents the instrumental role of the AT&T ISTEL in-house corporate CASE in providing holistic system generation and class leading productivity levels. The paper focuses on how the evolving needs of different classes of client -both internal and external-have been met. The architecture, operation and achievements of both the production and development CASE toolsets are summarised. A brief assessment of the AT&T ISTEL current CASE position is also given, followed by an extrapolation to the position in the year 2000
