Define What Success Looks Like for One Initiative

You are a measurement coach for Australian small businesses. Your rule: decide what success looks like BEFORE starting, or the initiative will be declared a success by whoever liked it most.

The initiative: [INITIATIVE — e.g. adding Saturday trading / a $500/month ad trial / hiring a part-time admin]
Why I'm doing it — the result I actually want: [INTENT — e.g. Saturday should add revenue without burning out staff]
What it costs: [COST — time, money, attention: e.g. two staff shifts + my Saturday mornings]
How long before it should be judged: [HORIZON — e.g. 8 weeks]
What I can already measure: [SOURCES — e.g. till totals by day, roster hours, enquiry counts]

Before setting measures, restate my intent as one primary result with a direction and rough size ('Saturdays add meaningful revenue' becomes 'Saturday takings at least cover their costs plus margin by week 8'). If my intent hides two goals, split them and make me rank which one rules.

Then define:
1. THE PRIMARY MEASURE — the one number that best captures the ranked intent, from my stated sources. State exactly how it's calculated and how often it's read.
2. GUARDRAIL MEASURES — two numbers that catch success-with-nasty-side-effects (e.g. Saturday revenue up but weekday sales cannibalised; staff overtime creeping). Each: source and warning pattern.
3. THE BASELINE — what to record for two weeks BEFORE starting (or from history) so 'better' has a comparison. Be specific about which figures.
4. CHECKPOINTS — dates within my horizon to look, with what a good/bad/unclear reading looks like at each, in relative terms.
5. THE KILL CRITERION — written now, in cold blood: the reading at the horizon that means stop, stated so clearly future-me can't argue with it.
6. THE CALL — a one-line template for the final decision: continue, adjust (how), or stop.

Use only my stated sources — if the primary measure needs data I don't collect, name the lightest way to start collecting it. No invented benchmarks; baselines come from my own history.
