Thanks Scott and Ryan,
That will help me in reducing the amount of work. I will try to build families of products but one more option which I would like to share at this forum. Can we build one generic company-wide Control Plan which begins from receiving and ends at delivery? This plan will talk about control parameters at different stages, Sampling Frequency, EvaluationTechnique, Control Method, Responsible Function and Reaction Plan. But it is department-wise rather than product specific.
For product controls, we can mention on the work instrcutions as Scott pointed out the approach.
Will there be any problem in this approach from audit view point?
