Systems Architecture, Requirements & MBSE

Mission and use-case definition, requirements, interfaces, budgets, model-based systems engineering, configuration control and technical baselines.

Revision 1.9.1 · Phase 2 content and navigation review

Public-safe engineering gateway: this page explains responsibilities, interfaces, work products and review evidence without publishing application-specific dimensions, algorithms, allowables or unreleased performance data.

Engineering Role

Why This Gateway Exists

This gateway keeps a multidisciplinary machine coherent from need through retirement. It defines operational scenarios, system boundaries, requirements, interfaces, budgets, baselines and the digital thread connecting decisions to evidence.

Questions This Team Must Close

Whose needs and operating scenarios define the system purpose?
How are functions and requirements allocated across disciplines?
Which interfaces and performance budgets require formal control?
How are changes, configurations and verification evidence kept traceable?

Controlled Engineering Scope

Six Level-3 Topic Pages

Each daughter page defines a focused technical responsibility, the interfaces it must control and the evidence expected as the design matures.

Level 3.1 · Stakeholder needs and operational use casesTranslation of user, mission, maintenance and environmental needs into bounded mechatronic operating scenarios.Level 3.2 · System decomposition and interface controlAllocation of functions and ownership across mechanics, electronics, optics, software and verification interfaces.Level 3.3 · Requirements allocation and traceabilityFlowdown, verification methods and bidirectional traceability from system outcomes to hardware and software requirements.Level 3.4 · MBSE, digital thread and technical baselinesModel-based architecture and controlled lifecycle data linking requirements, design, analysis, configuration and evidence.Level 3.5 · Performance budgets, margins and tradesControlled allocation and trade studies for mass, power, accuracy, bandwidth, latency, thermal load and reliability.Level 3.6 · Configuration, change and lifecycle controlIdentification, review and release of hardware, software, calibration and documentation configurations across service life.

Cross-System Integration

Interface Discipline

Systems architecture is the shared contract among mechanical, electrical, optical, software, human factors, safety, manufacturing and verification teams.

Requirements and operating modes

Physical and energy interfaces

Signals, timing and data ownership

Safety, security and fault behavior

Configuration and lifecycle change

Verification and acceptance evidence
