Standard operating procedure documentation is the task of generating, structuring, and refining written instructions that explain how to execute a specific business process consistently. You need this when you're documenting workflows, onboarding procedures, compliance steps, or repeatable operational tasks that teams must follow. Good models at this task produce clear sequential steps, identify decision points, flag exceptions, and write at the right technical level for your audience. Weak models create ambiguous instructions, skip critical details, or produce documents that require heavy revision. The main trade-off: speed models like GPT-4o complete SOPs in seconds but may miss edge cases, while slower reasoning models catch more gaps but add 30-60 seconds per document.

When to use: Use this when you need to create written instructions for how your team or customers should perform a specific task, process, or workflow, and you want an AI to help structure, draft, or refine those instructions quickly.
