The Integrated Software Development SystemHigher Order Software ISDSHOS 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 ISDSHOS is based upon a formal system theory, Higher Order Software HOS. The principles of ISDSHOS encompass all phases of system development and all disciplines including design, verification, documentation, management, and maintenance. The automated tools of ISDSHOS serve to eliminate many possible sources of human error in the transition of system development from concept to deployment. The component tools of ISDSHOS 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 ISDSHOS 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 ISDSHOS concept so that managers, systems engineers, and computer scientists can appreciate the various aspects of the basic principles on which ISDSHOS is based, the basic tools that ISDSHOS will have available, and the basic techniques that ISDSHOS users can use.
