It may be an informal system carried largely in the heads of supervisors or it can be a completely documented systems.

A documented quality system is one in which all aspects relative to quality assurance are approved and recorded. It includes objectives, policies, procedures, responsibilities work instructions, specifications and tolerances.

A document or a group of documents will formally demonstrate  to all interested parties, the attitude of a  company  to the subject of quality assurance. If a company can show that its documented quality system has satisfied an independent     assessing authority, then it can be regarded as one of “assessed capability”.
