    • IDT MAGAZINE – Second Issue ‫ر‬ IDT Page 2 “Dear my friend, I hope you are in excellent health and you are doing best in your daily life. I am writing my letter telling you a surprise I found In the Faculty of Engineering, Ain Shams University. Do you remember the last time we spoke about our dreams in powerful and competitive Egyptian industry? I never forget this day. We thought what if the industry here in Egypt is developed and how this development can change the face of life in Egypt. Do you remember? Our dream in more jobs for Egyptian citizens Do you remember? Our dream in strong economy leads Egypt to higher position between nations. The surprise, my friend, is that I found a group of engineering students who started this dream. I found the hope and the first steps towards tomorrow’s dream. I found youth’s enthusiasm, youths who are called “Industrial Development Team- IDT”.” This was a letter from an Egyptian citizen love his country and wants it to be the top.

    • IDT MAGAZINE – Second Issue ‫عا د‬ Page 21 What Is Production Control? The production control organization was established established in the early 1970s to provide a QA function for the legacy environment. These were its functions: second- • Provide second-level production support • Participate in the disaster recovery process/drills • Reject new applications or major revisions to production applications in production prior to thorough testing and documentation • Breed technical resources • Maintain scheduling requirements • Provide centralized ownership/accountability for key processes such as change management, storage management, etc. • Maintain system management toolstools • Assist senior systems programmers in installation, support, and documentation • Provide training to other groups within IT on newly installed system management tools Production Control versus Applications Development functions In the 1970s, one of the primary functions of the production control group was to accept or decline new systems/applications from applications development into what the infrastructure support staff considered the mission- sacred mission-critical production environment.
    • IDT MAGAZINE – Second Issue Page 22 Their job was to ensure RAS. On the other hand, the application development charter was to design, develop, and deploy a system into production as quickly as possible. Two Worlds Clash Nothing would enter the holy temple (data center) until the proper the documentation was provided, the appropriate staff was trained, and the application went through a very thorough QA process. The production control staff had as much power to decline a new system being deployed into production, as did the applications development staff for bypassing the normal process to expedite a system into production. There was no bargaining; it was production controls way or the system would end up in the departments broom closet, not supported by the production control group. caused. You can imagine the friction this caused. This dictatorial type of behavior by the production control staff lasted throughout the 70s and midway through the 80s. The one- mainframe process was one-sided in favor of the production control group. In the late 80s and throughout the 90s, as most companies companies transitioned to client/server computing in a decentralized environment, they did away with the production control function, and with it went the production QA function. Along with production QA went RAS. RAS was an afterthought. Some companies tried to keep this organization intact by changing the function dramatically. The perception was that production control was bureaucratic. As technology was evolving at a torrid pace in the late 80s and through the 90s, this perception became a
