Describes a project focusing on the experiences of implementing a third‐party certified quality system in small (maximum 50 employees) Swedish organisation. The project consisted of a questionnaire to CEOs, and then a more comprehensive case study of selected organisations. Results show that the more the CEO and employees have been involved in the implementation process, the more the system is used, that the CEO is more satisfied with the results; and quality improvements have continued after certification. Furthermore, the higher the level of education within the company, the less help has been required from external consultants. Indicates that important factors for a successful implementation are the attitude of the organisation when the implementation starts, that fairly detailed plans for the implementation are performed and that the documentation is adapted to the business and not necessarily to the ISO standard.
