    The papers in this issue of the ISM Systems Journal deal with the subject of installation management, specifically capacity planning and communications network management. The discipline of a systematic approach to the process of installation management helps bring about successful plans and operations. Capacity planning techniques may range from simple rules and procedures to complex benchmarking... View full abstract»

    The concepts and ideas of capacity planning may best be summarized by discussing how the process might be initiated and what the final product of a capacity planning effort might resemble. These concepts were developed from experiences with large data processing installations over the last four years. View full abstract»

    USAGE is an orderly procedure that starts by measuring an existing system. Like any effective management process, this should be an ongoing process. Projections should be tracked and rewordked periodically. The results of a study are useful for planning purposes, and as in any good management procedure, projections should be checked against reality. In capacity planning with USAGE, the results sho...

    SCAPE has been used as an aid for capacity planning in about 50 installations in the United States. In most instances, it has been of significant value in determining the optimal configuration for future use, justifying the procurement of hardware, or pinpointing possible bottlenecks. In addition, during the calibration phase of SCAPE, many users have gained a better understanding of their systems... View full abstract»

    In summary, FIVE provides sufficient detail to permit capacityplanning decisions to be made quickly and accurately, and without disrupting an ongoing operation. New applications can be accommodated, volume growth of existing applications can be planned for, and the effects of system changes can be assessed. The latter include such diverse elements as conversion from BSC to SDLC, screen and control... View full abstract»

    This paper has highlighted some of the MVS tuning experience of the IBM Washington Systems Center. Two points can be concluded from that experience. First, the predominant reason an installation finds itself in the midst of a performance crisis is because its performance management system is inadequate. Many performance problems can be avoided if objectives are set and an effective monitoring syst... View full abstract»

    The complexity of teleprocessing networks and the wide geographic distribution of both function and users hams ade the management task a highly critical one. The approach taken with the Account Network Management Program and the Network Error Management Facility is to provide the basic management discipline to ensure that all user requirements can be achieved. The programs by themselves cannot acc... View full abstract»
