To maintain SOP effectiveness, which activity is included?

• A. Circulate the SOP draft
• B. Issue copies of the finalized SOP
• C. Conduct periodic reviews of adherence to established SOPs and retrain periodically when necessary
• D. Finalize the SOP

Answer: (C)

Maintaining SOP effectiveness means continuously checking that people actually follow the procedures and keeping training up to date as things change. The best practice is to conduct periodic reviews of how well the established SOPs are being followed and retrain staff when necessary. This keeps the SOP relevant, catches deviations, and closes knowledge gaps so the procedures work in practice. Circulating a draft happens during development, not ongoing maintenance. Issuing finalized copies ensures access, but without regular adherence checks and retraining, effectiveness can drift. Finalizing the SOP is a development step, not a maintenance activity.
