Abstract

This document provides guidance on how to integrate the existing integrity processes within systems engineering, resulting in a more efficient and cohesive approach to engineering. In order to accomplish this, the Weapon System Integrity Guide (WSIG) contains three basic thrusts: <br>a. To integrate the efforts called out in the various integrity processes, namely: the Aircraft Structural Integrity Program (ASIP), the Engine Structural Integrity Program (ENSIP), the Mechanical Equipment and Subsystems Integrity Program (MECSIP), and the Avionics/Electronics Integrity Process (AVIP); <br>b. To synergistically integrate or coordinate specific integrity process efforts/tasks with related efforts in various other systems engineering disciplines; and <br>c. To place increased emphasis on the sustainment portion of the life cycle. <br>Applicability. Application of the WSIG to the design, production, and sustainment of systems is virtually unlimited. It applies to all elements of the weapon system (e.g., airframe, subsystems, avionics, engines, support, and training equipment) in all phases of life. Weapon system integrity applies to more than just new developments: it applies to system modifications (MODS), commercial off-the-shelf (COTS) equipment, use of form, fit, and functional interface (F³I) (interchangeable), changes in use, service life extension, and all of the corresponding changes in sustainment needed to maintain the integrity of performance. Each integrity process document referenced herein details specific activities to be accomplished during the various phases within a program. This guide integrates the integrity processes within systems engineering and provides a single contractual reference. <b><u>Intended Use:</u></b> This handbook provides guidance on how to integrate the existing integrity processes within systems engineering. This is accomplished through three basic thrusts: a. Integrating the efforts called out in the various integrity processes, namely: ASIP, ENSIP, MECSIP, and AVIP. b. Synergistically integrating or coordinating specific integrity process efforts/tasks with related efforts in various other systems engineering disciplines (see <a>table 1</a>). c. Placing increased emphasis on the sustainment portion of the life cycle. <br>
