Difference between Change control and Deviation please give the answer elaborately

Answer Posted / manusb07

Change control: It is a documented procedure wherein we can make changes in an approved procedure, process, equipment, method for better improvement without impacting the product quality and before implementing such changes, approval of Quality unit must be needed.All the changes made through change control procedures are PERMANENT, they are not TEMPORARY.

Deviation: There are two types of deviations Unplanned: It is the situation where we did not follow the written procedure which is against cGMP. in such cases a deviation is need to be filed and investigation must be done and accordingly CAPA must be taken. Planned: It is the situation where we can not follow the written procedure due to technical problem and we must deviate the procedure to process further. such planned deviation must be minor in nature and are for TEMPORARY only. Before making any planned deviation, Impact assessment shall be done. If we want to make such changes permanent then change control procedure must be used.

Anyone have any idea when to conduct Uniformity of Weight (UOW) and when need to conduct Uniformity of Dosage Units (UOD) or when need both? I read BP it only said if average weight < or = 0.04g then just conduct UOD, no need UOW. Under UOD section, it doesnt say when need to conduct UOD but just said UOD got two type, one is Mass Variation (MV), another is Content Uniformity (CU) and under what conditions to conduct them. For USP, no UOW section, only got UOD section.
