When Heinz Bons and Rudolf van Megen founded SQS in Cologne in 1982, they had little idea how rapidly their company would grow within the following years. From the very beginning they were convinced of the success of their idea, which was to sustainably optimise their customers’ business through high software quality.

Over the years, SQS has become the leading strategic quality partner for digital business. Building on its strength as the largest independent quality assurance specialist, SQS is now entirely focused on helping organisations manage their business and technology risk to achieve fit-for purpose business outcomes.

Many services and products have been introduced over time, including: automation platforms, AI platforms, agile and devops consultancy, quality governance frameworks, managed services, training and, most recently, business agility and management consultancy services. 

Clients choose us for our industry specific experience and technology IP, and regularly work with clients from across the globe on large transformation projects. 

However, our core purpose remains remarkably constant: to transform the world through quality assurance.
