Device gain - a measure of system component simultaneous operation

As computer systems become more complex and costly, the day-to-day efficient utilization of their capacity becomes more critical. At the same time, the system complexity makes analysis more difficult, and in some cases nearly impossible. It appears that an almost “standard solution” to the analysis problem is the replacement of the current system with a larger, faster, more complex, and more costly computer configuration. The need for accurate analysis leading to more appropriate management decisions is then postponed. Unfortunately, the cycle repeats itself and the inability to accurately assess the operation and performance of the computer system is now passed on to the new system. The effects of this analysis deficiency will not be immediately realized due to the increased speed and capacity of the new system. This type of solution, however, is becoming so very costly that it is imperative to find an alternative. It is in this context that this analysis and management tool is introduced.
