Information Systems in Management Science

Not all companies can afford, nor do they need sophisticated computer systems. The need for systems is dependent upon the nature of the business and the technical progress that the individual company and industry has made. It is important to point out that to a large extent the transaction business of most companies has been computerized. All large companies have computerized payroll. Billing is a universally accepted application. Many companies keep a perpetual inventory as part of their transaction files and update their chart of accounts as part of a payments system. Although these are not exotic applications, they represent a first step and a base load of work that computers do well.
