what is the detailed list of works should be done by person working in process quality stage in quality management system

Broadly classifying first and foremost activity is to determine where we are in terms of the quality frame work/standard we are planning to implement and come out with Gap analysis. Next step is to adress these gaps. Generally gaps falls under required process defination and implementation in the organization. Once process is defined and published at organization repository, It needs to be checked for compliance or adherence which is done by carrying out process audits. Apart from this process capability needs to be tracked often by carrying out process capability baselining and ensure process is under control and helping to acheive the required results.

As said by Mr.Jairaj Shyam Prasad, it starts from studying Control Plan and following "Check the cheker" and in my view you need to fix the "Limit Samples" at each stages of the process.

I would classify into following stages

1.Quality Assurance work procedures & Quality inspection plans.

2.Display product specification sheet & single point lesson at all manufacturing stages or workcenters & educate people on quality importanceby forming quality circles

3.Establishing mistake proofing activities like Visual controls at critical manufacturing stages to identify process deveations & eliminate rejections thereby improving Quality.

4.Cariying out Process capability studies & sigma value

It will be anything between: PDLC(Project development life cycle), Risk Management Plan, Process and Product Quality Assurance.
