Mission engineering (ME) is an interdisciplinary process encompassing the entire technical effort to analyze, design, and integrate current and emerging operational needs and capabilities to achieve desired mission outcomes.1 This style guide is intended to help mission architects apply Model-Based Systems Engineering (MBSE) approaches and the principles outlined in the Office of the Under Secretary of Defense for Research and Engineering (OUSD(R&E)) Mission Engineering Guide version 2.0 (MEG 2.0) to create mission architectures that inform Department of Defense (DoD) decision making. Mission architectures align mission outcomes, requirements, and capabilities in a systematic way through graphical representations that enhance stakeholders’ understanding of the mission space and associated problem areas. Artifacts are constructed to enable stakeholders to leverage completed studies, to run additional excursions, or extend the studies to address a greater scope. Mission architectures ensure both problems and potential solutions are systematically decomposed so that leadership and stakeholders can use them to make informed decisions.
Mission architecture modeling supports Mission Engineering Analysis through an iterative process of characterize, build, analyze and update. Digital modeling tools accelerate design cycles by providing a shared repository for information, allow reuse of model artifacts and enable the rapid reconfiguration of models to evaluate alternatives. Mission architectures help realize object-oriented systems engineering, enabling a digital life cycle representation. This guide provides examples for developing mission architectures to meet various stakeholders’ intent.
