Two functions necessary for managing a computer center (organizing and controlling) are discussed with a focus on a nomenclature that was found to be useful for identifying parts of a system and was compatible with the definitions of most operational systems. For example, it is necessary to identify files, reports, and programs used in daily activities within the data center. A job reference number with eight positions is described that specifies all the parts of items within a system. Nine items that are standard for system design, and that will reduce interface problems, are also covered. It is suggested that programmers use the same standards in coding and developing programs. Documentation is addressed with attention to the various sections within the computer center, particularly the three main areas of support: the systems and programming sections, the operational section, and the user's department. An outline of documentation by each section is included. Attention is also directed to (1) the benefits of using job reference numbers for job accounting, including cost reporting to control resources, and (2) the control function for the production areas of data management, production, resource management, and security. Specifically, consideration is given to the objectives and benefits of a good job accounting system, disk and tape data management, hardware reliability, error recovery, and security packages. (SW)
