Abstract : The Integrated Software Development System/Higher Order Software (ISDS/HOS) is a unified systems engineering methodology that includes a basic set of principles and a standard set of tools and techniques for developing computer-based systems. The foundation of ISDS/HOS is based upon a formal system theory, Higher Order Software (HOS). The principles of ISDS/HOS encompass all phases of system development and all disciplines including design, verification, documentation, management, and maintenance. The automated tools of ISDS/HOS serve to eliminate many possible sources of human error in the transition of system development from concept to deployment. The component tools of ISDS/HOS facilitate the specification of a system, automate interface analysis of the specification, and automate translation of the system specification directly into an optimized target-machine coded form. The ISDS/HOS support tools eliminate much of the manual effort required in the development of computer- based systems. The purpose of this report is to present the ISDS/HOS concept so that managers, systems engineers, and computer scientists can appreciate the various aspects of the basic principles on which ISDS/HOS is based, the basic tools that ISDS/HOS will have available, and the basic techniques that ISDS/HOS users can use.
