Management Information Systems is a general name for the academic discipline covering the application of people, technologies, and procedures—collectively, the information system—to business problems.
As an area of study it is also referred to as information technology management. The study of information systems is usually a commerce and business administration discipline, and frequently involves software engineering, but also distinguishes itself by concentrating on the integration of computer systems with the aims of the organization. The area of study should not be confused with computer science which is more theoretical in nature and deals mainly with software creation, and not with computer engineering, which focuses more on the design of computer hardware. IT service management is a practitioner-focused discipline centering on the same general domain.
In business, information systems support business processes and operations, decision-making, and competitive strategies.
Investing in information systems can pay off for a company in many ways.
an investment can support a core competency. Great companies invariably have one or two core competencies, something they can do better than anyone else. This could be anything from new product development to customer service. It is the heart of the business and no matter what it is, information technology can support that core competency. An IT investment in a company's core competency can create a significant barrier to entry for other companies, defending the organization's pnt system can be a major barrier to entry.
It can enhance distribution channel management. As with supplier networks, investment in distribution channel management systems can ensure quicker delivery times, problem free delivery, and preferential treatments. When the distribution channel management system is exclusive, it can mean some control over access to retailers, and, once more, a barrier to entry.
Such an IT investment can help build brand equity. To build a brand, firms often invest huge sums in advertising. A huge brand name is a formidable barrier to enter and sustaining it can be facilitated by investment in marketing information systems and customer relationship management system.
Information systems can mean better production processes (1). Such systems have become essential in managing large production runs. Automated systems are the most cost efficient way to organize large scale production. These can produce economies of scale in promotion, purchasing, and production; economies of scope in distribution and promotion; reduced overhead allocation per unit; and shorter break-even times more easily. This absolute cost advantage can mean greater profits and revenue.
IT investment can boost production processes (2). Information systems allow a company flexibility in its output level. Michael Porter claims that economies of scale are a barrier to entry, aside from the absolute cost advantages they provide. This is because, a company producing at a point on the long-run average cost curve where economies of scale exist has the potential to obtain cost savings in the future, and this potential is a barrier to entry.
Implementing IT experience can leverage learning curve advantages. As a company gains experience using IT systems, it becomes familiar with a set of best practices that are more or less known to other firms in the industry. Firms outside the industry are generally not familiar with the industry specific aspects of using these systems. New entrants will be at a disadvantage unless they can redefine the industries best practices and leap-frog existing firms.
IT investment can impact mass customization production processes. IT controlled production technology can facilitate collaborative, adaptive, transparent, or cosmetic customization. This flexibility can increase margins and increase customer satisfaction.
Leverage IT investment in computer aided design (1). CAD systems facilitate the speedy development and introduction of new products. This can create proprietary product differences. Product differentiation can be a barrier to entry. Proprietary product differences can be used to create incompatibilities between competing products. These incompatibilities increase consumers’ switching costs. High customer switching costs is a very valuable barrier to entry.
It means expanded E-commerce. Company web sites can be personalized to each customers interests, expectations, and commercial needs. They can also be used to create a sense of community. Both of these tend to increase customer loyalty. Customer loyalty is an important barrier to entry.
Information systems leverage stability. Technologically sophisticated firms with multiple electronic points of contact with customers, suppliers, and others enjoy greater stability. This monumental appearance of stability can be a barrier to entry, especially in financial services.
The simple fact that IT investment takes a significant amount of money makes it a barrier to entry. Anything that increases capital requirements is a barrier to entry.
The role of business information systems has changed and expanded over the last four decades.
In the incipient decade (1950s and '60s), “elecsystems” could be afforded by only the largest organizations. They were used to record and store bookkeeping data such as journal entries, specialized journals, and ledems” were used to generate a limited range of predefined reports, including income statements (they were called P & L’s back then), balance sheets and sales reports. They were trying to perform a decision making support role, but they were not up to the task.
By the 1970s “decision support systems” were introduced. They were interactive in the sense that they allowed the user to choose between numerous options and configurations. Not only was the user allowed to customize outputs, they also could configure the programs to their specific needs. There was a cost though. As part of your mainframe leasing agreement, you typically had to pay to have an IBM system developer permanently on site.
The main development in the 1980s was the introduction of decentralized computing. Instead of having one large mainframe computer for the entire enterprise, numerous PCs were spread around the organization. This meant that instead of submitting a job to the computer department for batch processing and waiting for the experts to perform the procedure, each user had their own computer that they could customize for their own purposes. Many poor souls fought with the vagaries of DOS protocols, BIOS functions, and DOS batch programming.
As people became comfortable with their new skills, they discovered all the things their system was capable of. Computers, instead of creating a paperless society, as was expected, produced mountains of paper, most of it valueless. Mounds of reports were generated just because it was possible to do so. This information overload was mitigated somewhat in the 1980s with the introduction of “executive information systems”. They streamlined the process, giving the executive exactly what they wanted, and only what they wanted.
The 1980s also saw the first commercial application of artificial intelligence techniques in the form of “expert systems”. These programs could give advice within a very limited subject area. The promise of decision making support, first attempted in management information systems back in the 1960s, had step-by-step, come to fruition.
The 1990s saw the introduction of the Strategic information system. These systems used information technology to enable the concepts of business strategy developed by scholars like M. Porter, T Peters, J. Reise, C. Markides, and J. Barney in the 1980s. The sustainability of these applications has since been called into question by N. Carr, which Piccoli and Ives, among others, have countered.
The role of business information systems had now expanded to include strategic support. The latest step was the commercialization of the Internet, and the growth of intranets and extranets at the turn of the century.
