What's the difference between QMS, Quality Manual, Quality Procedures and Quality Management Plan? When do all these need to be developed? Does an ISO certified, IMS implemented organization, working as a design, construction supervision, O&M and facility management company requires to develop QMP when it already has all IMS documents?
A QMS, as ISO 9000:2015 defines, is part of a management system related to quality. While implementing a QMS an organization may develop non-mandatory documents like a Quality Manual, a kind of the QMS’s identity card, Quality procedures, documents that set rules about how organizations should act in certain circumstances. Concerning what is a Quality Management Plan, that terminology is not very common with ISO 9001:2015. So, different people may mean different things. For example, a QMP may mean how the QMS is applied in a particular project.
Companies that work on a project basis, like construction companies, normally have to develop a QMP for each project. Many times it is a client request.
