Standard operating procedures (SOPs): meaning and format
An SOP is a written, step-by-step instruction for doing a routine task the same safe way every time. It follows a fixed format, from title to records.
What an SOP is and why it matters
A standard operating procedure (SOP) is a written, step-by-step instruction that tells workers exactly how to do a routine task, such as receiving milk, cleaning a slicer or cooling rice, so that it is done the same safe way every time. SOPs give consistency, help train new staff, fix responsibility, reduce errors, provide evidence for FSSAI inspections and audits, and carry out the monitoring and corrective actions of the HACCP plan. Good SOPs use short, numbered steps, simple words, the workers' own language and pictures where useful, and they give exact limits (time, temperature, strength of sanitiser).

How to write an SOP
- 1Choose the task from the hazard analysis or prerequisite programme list.
- 2Watch a skilled worker do it and note each step.
- 3Draft short, numbered, action steps with exact limits.
- 4Add responsibility, frequency, monitoring, corrective action and records.
- 5Test it with the workers and revise unclear steps.
- 6Approve, number and issue it; train staff and display it near the workplace.
- 7Review it regularly and whenever the process, equipment or law changes.
SOP vs checklist
A diet kitchen keeps SOPs for tasks such as preparing tube feeds or portioning low-salt diets, so every cook on every shift gives patients the same safe result.
