摘要:

Software provides the means to both approximate reality in functional models and alter these models as reality or our perceptions of it change. Unfortunately, three of our software engineering concepts have limited software's representation and adaptability. Consequently, many of us who are using these concepts are developing not software but brittleware, systems that are rigid and difficult to modify.

摘要:

Efforts to reduce the application backlog have run amok. Productivity tools and end-user computing, which were supposed to solve the problem, have only fueled the fire by encouraging end users to overconsume computing resources. Consequently, many MIS departments are turning to automated, PC-based application development. This article discusses the benefits of application development on workstations and lists steps and tips for product selection and implementation.

摘要:

Excessive maintenance costs can under-mine the success of any system. Benchmarking systems in development and maintenance can correct potential problems in new systems and monitor the maintenance effort expended for operational ones. This article suggests guidelines for establishing a benchmarking system.

摘要:

Diagramming is used in every stage of systems development and can be executed in various levels of complexity to accommodate both nontechnical users and MIS professionals. This article describes diagramming symbols, reviews each diagramming method individually, and discusses which techniques are best suited to each stage of systems development.

摘要:

Planning the use of computer technology is difficult for MIS managers who are unsure of how best to support business goals. And senior executives who feel that they must become experts in a technology to manage it are often reluctant to give these managers direction. A systems planning methodology such as IBM's Business Systems Planning (BSP) can bring the two together. It offers senior executives the opportunity to learn just enough to make good decisions regarding the use of expensive technology and helps the MIS manager ensure that the information systems developed further corporate objectives.

摘要:

The MIS department has coordinated the acquisition and distribution of PCs and software for many business purposes but has often overlooked word processing, a major office application. MIS may prefer to leave it where it is — on rapidly aging dedicated word processors. Consolidating word processing with other applications, however, not only results in cost savings but can also increase the flexibility of the organization's PC investment and enhance the productivity of both WP and non-WP users. This article presents a case for transferring word processing to PCs and highlights its advantages.

摘要:

Thanks to the proliferation of end-user computing, information processing is no longer limited to the MIS department. Because computer-processed and stored information is now available to staff and management throughout a corporation, the person responsible for planning, coordinating, and controlling the use of this vital resource must have organizationwide perspective and visibility. For an increasing number of companies, that person is the chief information officer.

摘要:

Millions of years ago, the dinosaur, a doomed species, roamed the earth. Today, three doomed MIS practices hold sway in MIS departments across the country: EBCDIC coding, nine-track tape storage, and excessive backup. It may be time for their extinction — or at least, planned retirement.

摘要:

Shifting trends in computer industry growth are a source of concern for MIS managers, who must understand the reasons behind the changes and adjust their purchasing plans accordingly. Increasing pressure from corporate management to justify acquisition decisions should force a healthy reexamination of your own assumptions.

摘要:

To answer the question, “What do CEOs think about information systems? ” first step back and ask, “What do CEOs normally think about? ”Effective CEOs spend almost all of their time thinking about problems and opportunities, and the information systems department that presents either is sure to get the CEO's attention.
