Offshore provision of IS/IT related services has been growing rapidly in recent years and seems firmly set to continue. This trend is fueled by the many advantages of offshore service procurement; however, there are dangers in this practice. Furthermore, offshoring requires adaptation of the IS function and IS management. This, in turn suggests the need for… (More)
Using readily available data on CPU characteristics—main memory size, cache memory size, number of channels, and machine cycle time—it is possible to predict relative CPU performance for a wide range of machines. Statistical analyses indicate that these characteristics explain virtually all the variance in relative performance.
Does Grosch's law, which postulated that the costs of computer systems increase at a rate equivalent to the square root of their power, still hold? The age of mini-, micro-, and supercomputers seems to have complicated the situation. When computers are grouped according to their size and power, Grosch's law seems to hold within each group, but not between… (More)
OBJECTIVES Develop a problem-orientated and data-based decision support system (DSS) to improve empirical antibiotic treatment, and compare the performance of the system to that of the physician. DESIGN The DSS was tested in a prospective, noninterventional, comparative cohort study. SETTING University hospital in Israel. SUBJECTS Consecutive patients… (More)
A method is presented for evaluating computer system performance in terms of a cost/utilization factor and a measure of imbalance. These coefficients indicate the extent to which the total system cost is effectively utilized. The method includes a technique for the visual representation of system performance.
