A planning cycle sets a small number of goals, measures against them, and adjusts.
Fewer goals than feels right
Three or four for a year. A list of twelve is a list of intentions, and in a business where the owner is also working, most of them will not happen.
The test of a goal is whether it is measurable and whether somebody owns it.
Tied to numbers the business already has
Goals expressed as figures already tracked can be checked without extra work — margin, average job value, recurring revenue, days to get paid. See key performance indicator (KPI).
A goal requiring a new measurement to be invented usually stops being measured by March.
The review is the point
Monthly against the budget, quarterly against the goals.
A plan written in January and next opened in December did nothing. The purpose is noticing early that something is not working, while there is still time.
Scenarios rather than a single forecast
What the year looks like if revenue is materially below plan, and what would be done about it. That is the useful part of contingency planning, and it is cheap to think through in advance.
The specific trigger matters more than the plan: at what cash balance, or what monthly revenue, does the business act rather than wait.
Long horizons
A five-year plan for a small service business is mostly a direction rather than a forecast, and it is worth treating as one. The useful long-range questions are about structure — owner dependence, recurring revenue, what the business is being built toward — see exit planning.
Benchmarks
Useful as a sense-check, unreliable as a target, because definitions vary between sources and trades. The business's own trend is the more reliable comparison — see service business benchmarks.
