Writing Your First Standard Operating Procedures
A standard operating procedure is a one-page record of how a recurring task gets done well in your business, and research on checklists and management practices suggests that a few short pages for the tasks that repeat most do much of the work.
At a glance
- A standard operating procedure (SOP) is a short written page that says when a task happens, what done looks like and the steps that get it there, so the task comes out the same whoever does it.
- Knowledge that lives only in people's heads walks out with them, and in 2025 U.S. private employers lost the equivalent of about 43% of their workforce over the year to quits, layoffs and other separations, according to the Bureau of Labor Statistics.
- In a study of 7,688 surgical patients in eight hospitals, a 19-item checklist cut inpatient complications from 11.0% to 7.0% and deaths from 1.5% to 0.8%.
- Start with the five tasks that happen most often and go wrong most expensively, write each on one page from a recording of someone doing it, then have someone else test it.
Part 1 | The business already has procedures; they just live in one head
Every service business that has stayed open for a year runs on procedures, because the opening routine, the way a new client is greeted, the order a technician works through a furnace check and the steps for closing out the day all happen in roughly the same sequence most days. The difference between a business with SOPs and one without is only where that sequence is stored, and in most owner-run businesses it is stored in the owner, which is why the same questions arrive at the owner's phone every week and why a good employee's last day takes a piece of the business with them.
The instinct that keeps procedures unwritten usually sounds like this: It's faster if I just do it myself. For any single occurrence that is true, since explaining a task takes longer than doing it, but the arithmetic changes once the task repeats every week and the explanation repeats with every new hire. Federal turnover data shows how often that happens; across all private employers, separations averaged 3.6% of the workforce each month in 2025, and service industries ran higher.
Research on management practices points the same way for small firms. A National Bureau of Economic Research study that surveyed microenterprises in seven countries found that firms with better record-keeping, stock-keeping, marketing and financial-planning practices had higher survival rates and faster sales growth, and a randomized experiment with large Indian textile firms, also published by NBER, found that adopting basic management practices raised average productivity by 11% through better quality and efficiency. Neither study looked at U.S. salons or plumbing companies, so the figures are a direction rather than a promise, and the direction is that written routines are one of the measurable differences between firms that grow and firms that stall.
Part 2 | What belongs on one page
The most cited evidence for short written procedures comes from medicine, where a team tested a 19-item surgical safety checklist in eight hospitals in eight cities, from Seattle and London to New Delhi and Ifakara, Tanzania, and published the results in the New England Journal of Medicine. The checklist did not teach surgeons anything new; it made sure a handful of steps everyone already knew, such as confirming the patient's identity and planned procedure, happened every time, and the results were large.
The lesson for a service business is about length as much as content. A useful SOP fits on one page and holds six parts: the name of the task; the trigger, meaning when it happens; what done looks like, written as something a customer or the owner could check; the steps, five to ten of them, each starting with a verb; the one or two tricky points where the task usually goes wrong, with the reason behind them; and who owns the page and when it was last checked. A front desk opening routine might run eight steps and fit on an index card, while a new-patient intake or a furnace tune-up might need a photo or two, but neither needs a binder.
Part 3 | Which five to write first, and how
The first SOPs should cover the tasks that repeat most and cost most when they go wrong, which an owner can rank by scoring each recurring task from 1 to 5 on how often it happens and 1 to 5 on what a mistake costs, then multiplying. In most service businesses the top five land in the same places: opening and closing, booking and confirming, the first visit or first job, taking payment and asking for the rebook or review, and the one technical task that brings the most comebacks or redos.
Writing each page goes faster from a recording than from memory. Have the person who does the task best do it while someone records on a phone, write the steps from the recording in plain words, hand the page to someone who has never done the task and watch them follow it without help, then fix every step where they hesitated and date the page. The test matters because an expert writing from memory skips the steps that have become automatic, and those are exactly the steps a new person misses.
| "How do we do this?" questions to the owner per week (Assumption) | 10 |
|---|---|
| Minutes per question (Assumption) | 6 |
| Weeks open per year (Assumption) | 50 |
| Owner hours spent answering per year (Calculated (10 × 6 × 50 ÷ 60)) | 50 |
| Value of an owner hour (Assumption) | $90 |
| Cost of owner time (Calculated (50 × $90)) | $4,500 |
| Redos or comebacks per month from a missed step (Assumption) | 3 |
| Cost per redo (time, product, discount) (Assumption) | $120 |
| Cost of redos per year (Calculated (3 × $120 × 12)) | $4,320 |
| Total yearly cost (Calculated ($4,500 + $4,320)) | $8,820 |
| One-time cost to write five SOPs (two hours each) (Calculated (10 hours × $90)) | $900 |
| Saving if the pages halve both costs (Calculated ($8,820 × 50%, Assumption)) | $4,410 a year |
Illustrative example; replace every assumption with your own numbers.
A page that nobody opens saves nothing, so each SOP should live where the task happens, such as a laminated card at the front desk, a shared folder on the tablet in the truck or a pinned note in the booking system, and each one should be reread whenever a mistake points to a missing step.
How you compare
- Turnover: if your industry replaces 40% to 70% of its workforce in a year, as the federal data above shows, a business of five people can expect to train two or three new people a year, each of whom will learn either from a page or from the owner's memory.
- Practices: the NBER survey found that small firms with better everyday business practices tended to survive longer and grow faster, so a business whose routines exist only in the owner's head has room to move up.
- Your own baseline: keep a tally for two weeks of every time someone asks you how to do something, which tells you both how many SOPs you need and which to write first.
Questions to ask this week
Which question do I answer most often? The task behind it is the first SOP to write.
Which task causes the most redos or complaints? Score it for frequency and cost, then put it second.
Who does that task best? Record that person doing it, even if it is you.
Could someone hired next month follow the page alone? Hand it to the newest person and watch, without helping.
Where will the page live? Put it where the task happens, not in an office drawer.
The first step is a two-week tally of the questions you answer and the tasks that go wrong, which gives you a ranked list of the five pages to write first.
About this research: This article draws on the Bureau of Labor Statistics' Job Openings and Labor Turnover Survey, a surgical checklist study of 7,688 patients published in the New England Journal of Medicine, and two National Bureau of Economic Research studies of management practices, one a survey of microenterprises in seven countries and one a randomized experiment in Indian textile firms. The hospital and manufacturing studies come from settings very different from a small service business, so their exact figures will not carry over; they show the pattern that short written routines change results. The worked example is illustrative.
