Quality at Sigma Technology



The Sigma Technology management system is ISO 9001:2015 (Quality), ISO 14001:2015 (Environment), and ISO 27001:2013 (Information Security) certified. These certificates prove our focus on processes and our commitment to delivering services of the highest quality. The management system is an integral part of all our projects and services. The ISO certifications require us to demonstrate that we measure our performance through our management system’s goals and key performance indicators.

All our projects and systems are audited internally, and our processes are audited both internally and externally. These audits are an essential part of our work towards continuous improvement. The customer satisfaction survey is another vital part of our continuous improvement.
Our operations in Sweden and Hungary are ISO 9001:2015, ISO 14001:2015, and ISO 27001:2013 certified, and our operations in China are ISO 9001:2008 and ISO 27001:2013 certified. We are constantly striving for success and aim to achieve the same quality standards for all of our operations globally.
