The author of the artide perceives a close relationship between an effective KMS (Knowledge Management System) in the SDO (Software Delivering Organization) and the guality of the software delivered by the organization as required by customers.

The above approach complies with the requirements and recommendations concerning die QMS as defined in international ISO standards.
