In May the British Standards Institute completed their audit of our quality management systems to ensure that we are still maintaining the requirements to meet the ISO 9001:2015 certification standards that was achieved in 2017. As part of the audit, and in line with the business objectives for continual improvement, a review for the requirements recently implemented by the Quality Assurance manager and engineering department to meet BS ISO/IEC/IEEE 90003:2018 (Software engineering — Guidelines for the application of ISO 9001:2015 to computer software) was undertaken. A satisfactory outcome was achieved and we now move forward knowing that our software-based applications, in particular the Airfield lighting control systems, come with further improved safety monitoring.
