Work instructions vs SOPs: which one does your team need?

Key takeaways

An SOP (standard operating procedure) describes a whole process: what happens, in what order, who does it and why. A work instruction describes how to do one task, click by click or step by step. An outsourced team needs both: one SOP per process and short work instructions for the tasks that cause most questions or errors.

• SOP: the whole process, who does what and in what order.
• Work instruction: how to do one task, step by step.
• One SOP per process; instructions for tricky tasks.
• Keep each instruction to one page or one short video.

What is the difference between an SOP and a work instruction?

An SOP is a process-level document. It lists the steps from start to finish, the roles involved, the decisions and the standards, and it explains why. A work instruction is task-level. It shows exactly how to perform one step, such as raising a credit note in your accounting system, often with screenshots. The SOP says what; the instruction says how.

When do you need each?

You need an SOP whenever more than one person or team is involved in a process, so everyone shares the same map. You need a work instruction when a task is fiddly, done rarely, error-prone or done in a system with many steps. Not every task needs one. Write instructions where questions and errors actually happen.

• SOP: any process shared across people or teams.
• Instruction: tasks with many clicks or system steps.
• Instruction: tasks done rarely, such as year-end jobs.
• Instruction: tasks with a history of errors.

• Video SOPs: train an outsourced team with screen recordings
• A social media SOP that keeps posting consistent

How much detail should you include?

Include enough detail that a trained newcomer can complete the task without asking. For an SOP that usually means one to three pages. For a work instruction, one page or a short screen recording. More detail is not better: long documents go unread. Put the exceptions and the reason for each rule where people will see them.

• Checklists that reduce errors in routine business work
• Internal knowledge base: answers your team can find fast

What does a good pair look like?

In an illustrative example, the SOP for customer refunds covers when refunds are allowed, who approves above £100, the steps from request to payment and the target turnaround. Two work instructions sit beside it: how to issue a refund in the payment system and how to record it in the accounts. Example structure only.

• Acceptance criteria: define done for outsourced work
• Escalation paths for outsourced teams: fast, not chaotic

How do you keep them up to date?

Give each document an owner and a review date, and update it whenever a question reveals a gap. Keep them in one place, such as a shared knowledge base, with the date of the last change visible. An outsourced team will often flag gaps first, so make it easy for them to suggest edits.

• The process owner: who keeps an outsourced process healthy
• Single source of truth: one place for each business fact

When is writing them a waste of time?

Writing them is a waste of time for tasks that are about to change, such as a system being replaced next month, or for one-off work. In those cases a short brief is enough. Write the documents once the process is stable.

• Should you fix a process before you outsource it?

What does this look like in practice?

A pattern we see: a business writes a 20-page manual for a handover and the team still asks basic questions. The manual describes the process but never shows the system steps. Adding three one-page work instructions for the tasks people actually ask about stops most questions.
