Human Factors Integration & Design Assurance

Introduction

Technical excellence alone doesn’t ensure operational success. Defence systems must also be usable, safe, and effective in the environments and scenarios they’re deployed into. Our Human Factors Integration & Design Assurance service supports delivery teams, engineers, and safety leads in embedding human-centred thinking across the system lifecycle, ensuring your solutions work in practice, not just in theory.

Drawing on JSP 912 and Defence Standard 00-251, we combine Human Factors Engineering with user-centred design to support Human Factors Integration (HFI) across all domains, including personnel, training, safety, and organisational aspects. Whether you’re producing a safety case, evaluating usability, or preparing for design assurance reviews, we provide the evidence and guidance to de-risk your programme and deliver systems people can trust and use effectively

What We Deliver

Our service spans both technical artefacts and integrated collaboration with delivery teams to make HFI real, early, and relevant. We provide:

• Human Factors Integration Plans (HFIPs) – tailored to your programme, life-cycle phase, and risk profile, supporting assurance and compliance from day one.

• Safety case contributions – including HF-specific inputs, assumptions, and evidence aligned to Def Stan 00-056 and other regulated frameworks.

• Task and workload analysis – identifying where users may be overloaded or unsupported, especially in high-risk or high-tempo scenarios.

• Cognitive walkthroughs and usability reviews – assessing how intuitive, learnable, and error-resistant your systems are under operational stress.

• Hazard logs and mitigation strategies – focused on user interaction, system complexity, and human-system integration challenges.

• Traceable evidence for design assurance – aligned to HFSRs and HFPRs as outlined in JSP 912, supporting audit, review, and stakeholder confidence.

We work closely with engineers, safety specialists, and user representatives to ensure HF is integrated, not isolated. Our approach is collaborative, pragmatic, and adapted to your delivery model.

What You Gain

This service ensures your system doesn’t just pass technical tests; it works with, for, and around its users. From cockpit layouts and UIs to mission workflows and maintenance procedures, we help you understand how your design performs in context and avoid the cost and risk of issues emerging too late.

By aligning with mandated Defence policy and good practices, you also strengthen assurance, build stakeholder confidence, and reduce lifecycle costs.

REDUCED SAFETY AND OPERATIONAL RISK

By identifying and addressing human-system interaction issues early, you avoid latent hazards, design flaws, and unworkable procedures that can lead to harm or failure.

DEFENSIBLE ASSURANCE

You gain traceable, evidence-based outputs aligned with JSP 912 and Def Stan 00-251. This is essential for safety cases, formal reviews, and gated approval processes.

GREATER USABILITY AND TRUST

Systems that reflect real user needs and limitations lead to better adoption, lower error rates, and higher confidence in operational settings.

INTEGRATED, MULTI-DISCIPLINARY ALIGNMENT

We work with engineering, logistics, training, and safety colleagues to ensure Human Factors are embedded across Defence Lines of Development, not treated in isolation.

EFFICIENCY ACROSS THE LIFECYCLE

HFI reduces long-term costs by limiting rework, shortening training time, and improving maintainability, ensuring that people remain an asset, not a workaround.

Our work brings assurance, clarity, and real-world credibility to complex systems. Whether you’re building new capabilities, evolving existing platforms, or fielding emerging technologies, we ensure they are safe, usable, and operationally effective by design.
