AS 3876-1991

This International Standard establishes guidelines for the documentation of computer-based application systems. It also contains checklists with the aim of supporting effective activities throughout the system life cycle.The guidelines given in this International Standard have been developed with the aim ofa) obtaining the necessary commitment of the parties involved with the development of the computer-based application system;b) contributing to the production of a well-planned, standardised system documentation;c) enabling the successive production of system documentation in parallel with system development.Wellûdefined rules for documentation during the process of system development will facilitatea) the preparation of the documentation itself;b) estimation of the time and resources required for the achievement of a project;c) exchange of information between the parties concerned, resulting in û selection of attainable objectives for a system; û a more complete and well-considered functional design;d) making decisions and briefing of personnel during work on system development.The system documentation produced in accordance with these guidelinesa) enables the management to exercise control over the development process;b) enables users of the system to use it efficiently and correctly;c) enables computer operators to schedule and run the system;d) aids diagnosis and correction of errors or faults;e) provides information about the system as support for system maintenance.
