Making systems that work
Independent consultant and hands-on practitioner on complex systems projects and major infrastructure programmes, from the first requirement to handover into service.

Four decades of systems that have to work first time
I'm Simon Wills, an independent systems engineer. For more than 40 years I've worked on systems that have to work first time: submarine sonar, air traffic management, critical space software, and, for most of the last 25 years, railways.
Through Xabrio, I bring that experience to the contractors and clients delivering some of the UK's largest rail and station projects, including the Bank Station Capacity Upgrade and HS2 at Euston. I've worked on both sides of the contract, embedded in delivery teams and alongside client teams.
I've worked as both consultant and practitioner. When I advise on how a project should be run, it's because I've done the job myself: written the requirements, managed the integration, assembled the evidence, and got the works accepted.
Four disciplines, one aim
Systems engineering
A systems-based approach to delivery, from stakeholder requirements through to verification and validation.
Technical assurance
Assurance regimes that show designs and completed works meet the client's requirements and standards, and get them accepted.
System integration
Integration strategies, interface management, and staged migration, so new and existing systems come together safely and with minimum operational risk.
Engineering management systems
Process frameworks and the individual processes beneath them, with the information systems that make them work, including IBM DOORS environments and DOORS extensions I've built myself.
Recent and current work
If your project needs a systems approach, or needs to show that what it delivers will be accepted, I'd be glad to talk.
