Abstract

The procedure of Information Systems (ISs) design aims to assist in the discovery of that solution which shall both cover in the best possible way the users' demands and also be feasible within the framework of the data processing environment of the corporation. In general, a good ISs design should possess the following characteristics: to be acceptable by all users, to be auditable, to be functional, to face problems "head on", to be satisfactory, not to be costly, to be easy in its development, maintenance and operation, to be will documented, and to be easily evaluated. It is believed that the above presuppositions are covered, to a great extent, by the proposed procedure. Keywords: information systems, procedures, development, maintenance, operationability. 1 General comments, purpose It is important for the ISs design to start with an itemization of all the necessary steps which will be taken for its implementation (initial outline design), because this will ensure a large probability for the design to be both correct and satisfactory. The itemization of these steps—i.e. the outline, or scenaric design—must be based upon: - the grouping of the new system's requirements, - the detection of the necessary presuppositions, - the classification of cases into categories:
