Our ISO 9001 Quality Management System


We have operated a BSI certified ISO9001 Quality Management System (QMS) since 2003 with our scope of our registration being “Process control, software design, validation, consultancy and training “. We have a defined Quality Policy and our QMS is regularly audited by 3rd parties. In February 2018 our QMS was audited by BSi and considered compliant with ISO9001:2015.

The QMS was, and continues to be, influenced by our knowledge and regular use of GAMP 5 (Good Automated Manufacturing Practice). GAMP is a standard used by the pharmaceutical industry and acts as the definition of good practice for designing, testing and validating automated systems.

At the end of a project, we canvas our clients for their opinion on the level of service they have received from us. This is based on eight categories, each of which are marked between 1 (Poor) and 10 (Excellent). Some clients go further and provide testimonials which can be found on the home page of this site. All past audits and client feedback are available on request.
