Although computer system families have historically been well served by unique operating systems and user interfaces, the growing tendency to install personal systems to operate as terminals to, and in networks with, work-group systems and enterpriselevel mainframes has led to fresh thinking on systems design and architecture. Interchanging people skills, programming, and data among systems requires bath working standards and common supporting software for programmers to use in interacting with the user as well as the operating system. For IBM the solution was seen as not only providing these common standards, formats, protocols, and architectures, but doing so in a manner that allowed for future growth and extensions, and that allowed applications to exploit the unique features of specific systems. IBM has chosen to call this solution Systems Application Architecture (SAA).
