Appendix F. Evolving in the 1970s and 1980s

Appendix F. Evolving in the 1970s and 1980s

The new IT products offered in the 1960s radically changed the way business was conducted. Closely linked to this phenomenon was the IBM System/360 (S/360), which was arguably the single most significant event in the advancement of IT in business and society. This new hardware and software architecture produced a truly general-purpose computing system and revolutionized the industry to a degree that is not likely to be seen again.

The popularity of general-purpose computers in the 1960s demonstrated the need for the systems management functions regarding batch performance and system availability. During the 1970s and 1980s these functions continued to evolve in both scope and sophistication. As online transaction processing—with its large supporting databases—became more prevalent, functions such as online transaction tuning, database management, and asset security were added to the responsibilities of systems management. The continued refinement and sophistication of the microchip, combined with its plummeting cost, also opened up new hardware architectures that expanded the use of digital computers. This appendix will discuss the evolution of these functions.
