3. Clean as per the procedure
4. Sample for product residue, cleaning-agent residues, and others
5. Repeat twice more, giving three (3) consecutive runs
6. Develop on post-cleaning monitoring strategies

WQ-7.   Describe the primary process principals of a typical pharmaceutical tabletting operation. List three (3) critical parameters that must be controlled.
