Briefly discuss the value (quality) of information (MIS)

The study of information systems, originated as a sub-discipline of computer science, in an attempt to understand and rationalize the management of technology within organizations. It has matured into a major field of management, that is increasingly being emphasized as an important area of research in management studies, and is taught at all major universities and business schools in the world.
Information systems deal with the development, use and management of an organization's IT infrastructure.
In the post-industrial, information age, the focus of companies has shifted from being product oriented, to knowledge oriented, in a sense that market operators today, compete on process and innovation, rather than product : the emphasis has shifted from the quality and quantity of production, to the production process itself, and the services that accompany the production process.
The biggest asset of companies today, is their information, represented in people, experience, know-how, innovations (patents, copyrights, trade secrets), and for a market operator to be able to compete, he/she must have a strong information infrastructure, at the heart of which, lies the information technology infrastructure. Thus, the study of information systems, focuses on why and how technology can be put into best use to serve the information flow within an organization.

(Introductory note by Detlev Fischer:) John Lindsay wrote his book over the late eighties and early nineties, and although technology has moved on a lot over the last fifteen years, the fundamentals and many of the issues discussed here are all valid.
