摘要：This article studies the proposition that firms of different sizes manage their computer operations differently, and it seeks to determine whether small firms face special circumstances in their uses of computers. The author presents several hypotheses which associate computer related variables with differences in firm size. These hypotheses are tested using data collected from seventy-four Los Angeles manufacturing firms of various sizes. The results indicate that selected computer-use charac...

摘要：Managers face a dilemma in assessing DSS proposals. The issue of qualitative benefits is central, but they must find some way of deciding if the cost is justified. A general weakness of the cost-benefit approach is that it requires knowledge, accuracy, and confidence. about issues which for innovations are unknown, ill-defined, and uncertain. The benefit of a DSS is the incentive for going ahead. The complex calculations of cost-benefit analysis ale replaced in value analysis by rather simple ...

摘要：Information Systems (IS) is facing a dilemma: software is absorbing an ever-increasing proportion of the total IS budget while maintenance is absorbing an ever-increasing proportion of the software budget. In the not too distant future, unless this trend is arrested, or reversed, nearly all software resources may be required for maintenance. There are certain projected developments which give hope for the future though not in the short term. In the meantime IS management must use other approac...

摘要：Any discussion of Decision Support Systems must of necessity include the MIS manager. It is crucial that the MIS manager understand the need for and the role of DSS in the full context of Information Resource Management, if a workable DSS environment is to be created. First, to facilitate this understanding, the need for DSS is established by examining the effectiveness of data processing in meeting organizational goals. Business Problems and opportunities are considered in the light of typica...

摘要：A new computer auditing technique, called Continuous and Intermittent Simulation (CIS), is introduced. It has been specifically designed as a compliance auditing technique for timesharing systems that can be used to audit internal controls. CIS is an auditing technique that simulates the instruction execution of the application at the time the application is processing a transaction. All data and input to the application is accessible by and shared with the simulation. This means that the simu...

摘要：The work reported in this article concerns the development and application of a radically new system architecture. This has been found, through controlled experimentation, to have substantial impact on managerial effectiveness and on the productivity of the firm's supporting white collar labor force. The article describes the motivation which first gave rise to these efforts and the solution developed to address the motivating problem. It describes a general model of the cost of information co...

摘要：Information systems planning is of growing interest to many MIS practitioners. This article postulates that one key element missing from most literature on systems planning is the transition from a strategic plan to an executable, operational plan. The article then describes the application of structured tools and methodology to assist in improving this transition task. The process and the examples explained in the article were taken from the author's experience in implementing them while at O...
