Join us for a complimentary one-hour consultation. During this session, we will provide personalized strategies to help realign your project, which began with great promise and is back on the path to success. We will explore your challenges and offer actionable insights to revitalize your project's momentum.

We provide mission-critical consulting across the full lifecycle of complex defence and cyber-physical systems. Our services are tailored to align with NATO, DoDAF, and national military standards, ensuring compliance, interoperability, and operational superiority from concept to deployment.
Each phase of the lifecycle is supported by expert guidance in modelling, verification, and digital engineering to enhance traceability, reduce risk, and accelerate readiness.
Your advantages
1. Stakeholder Needs, Problem Space & Early Concept Development
The first phase focuses on engaging stakeholders to capture mission needs, operational constraints, and high-level capability expectations. We support the definition of the problem domain, system scope, and early feasibility boundaries through structured workshops, stakeholder mapping, and mission scenario analysis. We document use cases, pain points, and boundary conditions while laying the foundation for a traceable requirements hierarchy. These efforts ensure alignment with operational objectives and serve as a launch point for architectural and systems thinking.
2. Concept Formulation & Enterprise Architecture
Once the problem space is understood, we define the conceptual and technological solution space. This includes identifying enabling technologies, use case candidates, and conceptual frameworks that support military doctrine and CONOPS. We leverage frameworks such as DoDAF 2.02, NAFv4, and UAF to develop layered enterprise architectures, capturing operational, systems, and technical views. This ensures that the future system is interoperable by design, compliant with NATO C3 taxonomy, and aligned with national defence strategies.
3. Functional Architecture & Analytical Prototyping
We then support the derivation of functional requirements and the development of logical solution architectures. Through MBSE practices and tools like SPARX EA, we decompose the system into its functional components, define information and control flows, and validate early hypotheses through simulation and analytical prototyping. This phase verifies that the system logic satisfies stakeholder intent and mission-critical performance thresholds under simulated operational conditions.
4. Physical Architecting & System Requirements
In this phase, logical functions are mapped to physical subsystems, and detailed system requirements are developed. We provide structured requirements engineering aligned with ISO/IEC/IEEE 29148. We model interfaces, assess constraints (e.g., power, weight, size, timing), and ensure verification criteria are embedded in each requirement. Trade studies are conducted to optimise the architecture across capability, cost, and risk dimensions. This phase culminates in a mature, traceable, and testable system specification.
5. Test Strategy, Verification & Validation Planning
The validated system architecture is transitioned into a fully designed and allocated system design. We facilitate detailed subsystem definition, integration planning, and create baseline reviews. This includes algorithm design, physical decomposition, and support for hardware-in-the-loop (HIL) and software-in-the-loop (SIL) prototyping. We ensure that the system is integration-ready, risk-managed, and aligned with safety, interoperability, and performance mandates.
6. Systems Design & Subsystem Integration Planning
We define a test strategy that encompasses the full verification and validation (V&V) lifecycle. This includes the development of test cases for functional, design, and system-level verification, aligned with standards such as MIL-STD-810, ARP4754A, and ISO/IEC/IEEE 29119. STPSE supports the definition of scenario-based tests, edge case simulations, and performance envelope validation. All test artifacts are model-based, traceable, and fully aligned with the requirements framework.
7. Deployment, Certification & Mission Readiness
With test evidence in place, the system is prepared for final deployment and certification. We assist in navigating certification requirements, whether for military accreditation, airworthiness, or NATO interoperability. We coordinate safety case development, cybersecurity validation (e.g., NIST 800-160, Zero Trust Architecture), and final operational assessments. Documentation and traceability are tightly managed to ensure full lifecycle evidence is available for auditors, customers, and certification authorities.
8. Technical File, Compliance & Sustainment Readiness
Finally, we provide structured support for generating the full Technical Data Package (TDP), ensuring compliance with defence documentation standards such as DEF STAN 00-55/56, MIL-HDBK-516C, and STANAG 4107. We compile safety cases, software and firmware documentation, configuration baselines, operational manuals, and post-deployment compliance artefacts. This ensures systems are not only ready for delivery but also prepared for long-term sustainment, updates, and secure lifecycle management.
Our Expertise
We specialise in Model-Based Systems Engineering (MBSE) for complex, mission- and safety-critical systems across the defence and aerospace sectors. Our core strengths lie in system architecture, requirements engineering, and model-driven verification, ensuring compliance with international standards such as ISO 15288, DoDAF, NAFv4, MIL-STD-882E, and NATO STANAGs. We integrate logical and physical design using tools like SPARX EA and support full lifecycle development, from stakeholder needs through to certification and sustainment. With deep expertise in safety engineering (FHA, FMRA, FTA), digital systems, and secure-by-design architectures, we ensure systems are robust, interoperable, and future-ready. Our approach is strategic, standards-driven, and focused on delivering operational advantage through precision systems engineering.

Our MBSE education equips professionals with the mindset and methodology to master complexity. Moving beyond traditional, domain-specific development, MBSE enables a holistic, function-driven approach to system design. It fosters collaboration across software, electronics, mechanics, and human factors, ensuring each component serves a mission-critical role within a cohesive system. Participants will gain hands-on insight into the lifecycle of intelligent systems, understanding how to architect, model, and manage multi-domain solutions that are powerful, practical, and ready for market deployment. This programme is tailored for engineers, managers, and innovators who aim to lead in a world where systems thinking is no longer optional, but essential.
