QUALITY PROMISE

Quality has been a central strategic priority since our founding in 1998.

A relentless focus on improving our software development and systems engineering processes has brought us to internationally recognised levels of organisational and process maturity.

Quality shapes our attitudes, our ways of working, and the processes and methodologies we apply across every engagement.

Embedded deep within our values and culture, quality provides the framework through which we operate with consistency, confidence and efficiency.

Our Integrated Management System is certified to CMMI-DEV Maturity Level 5, ISO 27001, ISO 9001, EN 9100, and NATO AQAP 2210 & 2310 — among the most rigorous standards in the industry.

The European Space Agency selected us as pilot pioneers for SPiCE 4 Space (S4S), grounded in ISO 15504 Process Assessment. We also serve as a review committee member for ESA-ECSS standards, including IV&V.
