Quality has been of central strategic importance since our formation in 1998.
The continuous improvement of software development and systems engineering processes has allowed us to reach outstanding, internationally-recognised standards in organisational and process maturity.
Quality is embedded in our attitudes, in the way we work, in our software development processes and in our methodologies.
Quality is embedded deep within our values and culture, providing a key framework for us to operate systematically, confidently and efficiently.
Our Integrated Management System (IMS) is certified according to CMMI-DEV Maturity Level 5, ISO 27001, ISO 9001, EN 9100 and NATO AQAP 2210 & 2110 standards.
We were selected by the European Space Agency to be pilot pioneers for SPiCE 4 Space (S4S) based on ISO 15504 – Process Assessment, and we're a review committee member of the ESA-ECSS standards (e.g. IV&V).
