Enterprise Engineering: A Comprehensive View, Planning, Governance, and Systems of Systems

Introduction

Have you considered whether your work must support an international community, interoperate with other federal agencies, or be affected by performance characteristics beyond your control? MITRE systems engineers (SEs) aim to bring an enterprise perspective to activities of any scale—from subsystems to whole enterprises—by taking a holistic view of technical and non‑technical aspects, asking exploratory questions, and tracing the implications of potential answers.

Background

MITRE defines an "enterprise" as a network of interdependent people, processes, and supporting technologies that is not fully controlled by a single entity. This includes companies, government agencies, large information‑centric organizations, and any entity network that collaborates to achieve explicit or implicit goals, often integrating previously independent units and exhibiting emergent behavior.

MITRE supports sponsor‑specific needs and must understand the enterprise environment surrounding those activities. Through projects such as the Semi‑Automatic Ground Environment (SAGE), MITRE has long addressed national‑defense enterprise requirements and developed radar solutions for protection.

Enterprise engineering assumes that an enterprise is a collection of entities that seek success and adapt to it. The process shapes the environment, incentives, and success rules for organizations that innovate and operate for both local missions and enterprise benefit, coordinating efforts through evolution‑inspired processes rather than direct control.

The main themes for MITRE SE engineering enterprise solutions are: 1) taking a comprehensive view, 2) enterprise planning and management, 3) enterprise technology, information, and infrastructure, 4) solving complex problems in information‑intensive environments, 5) engineering systems for mission assurance, 6) transformation planning and organizational change, 7) understanding enterprise governance, operations, assumptions, and constraints, and 8) independent engineering assessment.

Comprehensive View

A comprehensive view helps MITRE SEs create solutions that consider many factors across the enterprise, including favorable paths and operating environments. Tools such as systems thinking, uncertainty analysis, and complexity‑aware system‑engineering strategies support this perspective.

Enterprise Planning and Management

From a strategic angle, federal organizations must plan and manage how they achieve their missions, often without detailed legislative guidance. Sponsors may request MITRE SE assistance in developing and executing these strategic plans, covering IT governance, portfolio management, and measurement capability development.

Enterprise Technology, Information, and Infrastructure

This domain refers to shared IT resources and data across the enterprise, encompassing infrastructure engineering, IT service performance monitoring, IT service management, information management, and spectrum management.

Engineering Information‑Intensive Enterprises

MITRE’s role in federally funded research and development centers places it in environments where solutions primarily support information‑intensive functions. Work may involve hardware or platform considerations, but the focus remains on meeting sponsors' information needs through architecture integration, design patterns, agile techniques, on‑demand composition, open‑source software, privacy engineering, and testing.

Systems of Systems

Recognizing the importance of end‑to‑end performance, sponsors increasingly require integration across multiple systems. System‑of‑systems (SoS) engineering addresses capability gaps by coordinating across individual systems, and MITRE SE articles cover topics such as engineering in SoS contexts and lifecycle processes.

Mission Assurance Systems Engineering

Designing systems that survive purposeful or accidental failures and environmental changes is a long‑standing discipline. Modern mission‑assurance engineering expands to include information assurance and cybersecurity, emphasizing options, alternatives, risk assessment, and hybrid technical‑operational solutions.

Transformation Planning and Organizational Change

Transformation planning coordinates change activities so users can adopt new visions, missions, or systems. MITRE SE assists in strategic planning, stakeholder assessment, effective communication, and user adoption programs.

Enterprise Governance

Governance involves interactions and decision‑making among actors addressing collective problems, creating or reinforcing social norms and institutions. IT governance links business focus with IT management to ensure investment value and reduce project risk. MITRE SE must navigate and sometimes bypass governance structures to achieve enterprise goals.

MITRE FFRDC Independent Assessment

MITRE SE conducts various independent assessments—reviews, red‑team exercises, audits, and compliance evaluations—to identify project risks, provide objective expertise, and avoid conflicts of interest.
