A system development life cycle (SDLC) process is usually applied to a system with clear requirements definitions, well structured processing and reporting and a long, stable life expectancy, whereas a prototyping process is a better choice for a system with constantly changing requirements, ad hoc reporting and a transient life expectancy. A prototyping process may be used along with an SDLC process to shorten development time; the software testing process and test activities in a large system project following the SDLC approach are discussed. The three main stages of an SDLC are definition, development, and installation and operation: definition includes service request/project viability analysis, system requirements definition and system design alternatives; development includes system external specifications, system internal specifications, program development and testing; installation and operation include conversion, implementation and post-implementation review/maintenance.

United Services Automobile Association (USAA) has a long-range strategic systems plan that has become a corporate way of life since the beginning of the plan in 1980. Attention to emerging technology is part of the corporate organizational structure. A special advanced technology group was formed two years after the strategic systems plan was drafted at USAA. A research and development review committee monitors the activities of the technology group. One outcome of the endeavor is an image processing system implemented after six years of research and prototyping by the insurance company. Customer relations, productivity and management support have improved. The firm has eliminated 39,000 square feet of office space previously needed to support claims and correspondence. About 160 file managers and delivery clerks were fired as a result of the reorganization.
