# What is a standard operating procedure (SOP)? > An SOP is a written, step-by-step way to do a recurring task the same way every time. How AI turns rough notes into SOPs your team will follow.

A good SOP says who does each step, in what order, and how to tell it was done right. ## Why it matters for a small business Small businesses run on what a few experienced people know. When they are out, or when you hire, that knowledge has to be written down or the work drifts. SOPs make training faster, cut repeat mistakes and let you hand off work without standing over someone's shoulder. The reason most businesses don't have them is that writing SOPs is slow and dull. AI is good at exactly this job: turning a manager's rough notes into numbered, consistent steps. The risk is filler. A generic AI SOP says "ensure quality standards are met," which nobody on a dock can act on. The fix is a strict format and a rule against guessing. ## In a real lesson: Build an AI SOP Writer with a Custom GPT In the [AI SOP Writer lesson](https://learn.ynteractive.com/content/ai-sop-writer-custom-gpt-operations), you first ask plain ChatGPT to "Write an SOP for receiving an inbound shipment at our warehouse." The result is full of words like stakeholders, with steps like "check for any issues," and no owners, no numbers and no way to tell when the job is done. Then you build a Custom GPT called **SOP Writer** for Ridgeline Supply Co., a made-up warehouse business with 22 people and 4 dock doors. The instructions set a format worth copying for any SOP: start with a code and title such as "SOP-REC-01: Receiving an Inbound Shipment," then owner, where it applies and how long it takes; numbered steps with one action each, starting with a verb; the role in brackets, like (Dock Associate); a "Check" line for the supervisor; an "If something goes wrong" line; and no more than 8 steps. Two content rules do the most work: "If the notes are missing a detail, write [CONFIRM] in its place. Never guess," and safety steps always come first. You attach **Ridgeline-Operations-Handbook.pdf** so the GPT uses real roles and areas instead of inventing them.

A checklist is the short version used on the floor to confirm nothing was skipped. The SOP Writer GPT does both: asked for a checklist, it uses check boxes and keeps each line under 10 words. ### SOP vs policy A policy says what the rule is ("every pallet is labeled"). An SOP says exactly how to follow it. You usually need both, and the SOP should point back to the policy. ## Tips - Write each step so a new hire could do it on day one. If a step needs judgment, say what to look for. - Have the person who does the job read the AI draft before anyone else. They will spot the missing step. - Search every AI-written SOP for [CONFIRM] placeholders before you publish it. ## Related terms [Custom GPT](https://learn.ynteractive.com/content/glossary/custom-gpt) · [GPT instructions](https://learn.ynteractive.com/content/glossary/gpt-instructions) · [Knowledge files](https://learn.ynteractive.com/content/glossary/gpt-knowledge-files) · [Output format](https://learn.ynteractive.com/content/glossary/output-format) · [Prompt constraints](https://learn.ynteractive.com/content/glossary/prompt-constraints) ## Where to learn more [AI for Operations](https://learn.ynteractive.com/content/industry/operations) ## Prompt templates that use it [Checklist from SOP prompt](https://learn.ynteractive.com/content/prompts/checklist-from-sop-prompt) · [First-week training plan prompt](https://learn.ynteractive.com/content/prompts/first-week-training-plan-prompt) · [Month-end close checklist prompt](https://learn.ynteractive.com/content/prompts/month-end-close-checklist-prompt) · [Safety toolbox talk prompt](https://learn.ynteractive.com/content/prompts/safety-toolbox-talk-prompt) ## Frequently asked questions **How long should an SOP be?** As short as the task allows. The lesson caps each SOP at 8 steps and under 200 words; longer processes are usually several SOPs. **Can AI write SOPs from scratch?** It can draft the shape, but the facts have to come from you: who does the job, where, and the numbers that matter. Give it rough notes, not just a title. [All AI glossary terms, A to Z](https://learn.ynteractive.com/content/glossary) · [Free prompt templates](https://learn.ynteractive.com/content/prompts)
