'''Systems Application Architecture''' ('''SAA''') is a set of standards for [[computer software]] developed by [[IBM]]. The SAA initiative was started in the early 1970s <ref> Refer to [[IBM 3767]] and [[IBM 3790]]. </ref> and further enhanced in 1987 under the leadership of [[Earl Wheeler]], the "Father of SAA".<ref>{{cite news|last1=Bride|first1=Ed|last2=Desmond|first2=John|title=Wheeler: father of SAA - IBM VP and General manager of programming Systems Division Earl Wheeler; Systems Application Architecture - interview|url=http://findarticles.com/p/articles/mi_m0SMG/is_n15_v9/ai_8048960/|accessdate=June 20, 2012|newspaper=Software Magazine|date=Dec 1989}}</ref> The intent was to implement SAA in IBM [[operating system]]s including [[MVS]], [[OS/400]] and [[OS/2]]. [[IBM AIX|AIX]], IBM's version of the [[UNIX]] operating system, was not a target of SAA, but does have interoperability with the SAA family.

SAA did not define new standards, but selected from among IBM's existing guidelines and software. IBM also purchased some third party software from developers such as [[Bachman Information Systems]], Index Technology, Inc., and [[KnowledgeWare|KnowledgeWare, Inc.]]<ref>{{cite news|title=IBM kauft sich für SAA Software-Know-how ein|url=http://www.computerwoche.de/heftarchiv/1989/35/1151816/|accessdate=June 21, 2012|newspaper=Computerwoche|date=1989-08-25}}</ref> These were intended to be implemented uniformly across all SAA compliant environments.
