HOW TO PREPARE DOCUMENTATION IN INDUSTRY

                              DOCUMENTATION

INTRODUCTION :-

Documentation is covered by the Drugs Cosmetic Act 1940/Rules 1945 and is explained in schedule U of the said act.

Any anomoly in the documentation, if not explained properly by the staff, is deemed to be violation and the company is liable for penal action. Hence documentation must be taken as an individual responsibility and must be given the importance, it deserves.

Documentation is relevant in every phase of production facility, be it stores department to receive and dispense the material or Production department to produce the formulation or Quality Control department to carry out raw material/in process/finished product testing or Quality Assurance department to release the final goods to the customer.

Proper documentation is a primary requirement of CGMP (Current Good Manufacturing Practices) and it is indeed imperative that each member of the staff must be careful about documents under his/her control. The emphasis must be on zero defect, so that the final document kept as a record, will be defect free.
