Systems Application Architecture (SAA), introduced in 1987,[1] is a set of standards for computer software developed by IBM. The SAA initiative was started in 1987 under the leadership of Earl Wheeler, the "Father of SAA".[2] The intent was to implement SAA in IBM operating systems including MVS, OS/400 and OS/2. AIX, IBM's version of the UNIX operating system, was not a target of SAA, but does have interoperability with the SAA family.
