Software standards & process definition

These form the foundations that the technical solution will be built upon, Our early definition of these will ensure maintainability, certification and reduce the impact and cost due to future modifications.

Full-lifecycle development & verification

Our full-lifecycle ownership allows you to focus on the system and product, allowing us to do what we do best and provide a complete verified compliant software solution.

Requirements definition


Decomposing your System requirements into a set of Software requirements or performing a requirement capture activity, will give you the confidence that we can describe and agree on the success criteria of the software’s performance.




Our Software architecture will ensure all stakeholders understand the software structure allowing the engineers to work in parallel in confidence and reducing the impact to cost due to any future increases in size and complexity.

Design and Implementation


With extensive experience in a broad range of tools, languages and design methodologies, Our software team can design and implement from board support packages and low level drivers to application control and monitoring functionality.

Independent verification & validation

Our dedicated independent verification team has over 30 years of experience, of all types of software V&V, using a broad range of commercial and bespoke tools to implement functional and robustness testing, from unit to integration test.

Legacy system updates

With complex electronics in service for decades, modification, upgrades and obsolescence are common place, We have extensive experience of taking ownership of old systems and toolchains and migrating/updating to ensure functional and standards compliance.

Graphical HMIs


Our experience in developing dynamic interactive real-time graphical HMIs for complex solutions like avionic displays, allows rapid ‘look and feel’ prototyping to allow your front-end system to be refined as the project progresses.

Full Certifiable solution

Our 30 + years of high integrity development and verification experience, up to DAL A/SIL 4 gives you the confidence that our processes will ensure a certifiable software solution.
