SMART goals — a wish you can check

Specific, Measurable, Achievable, Relevant, Timely: where the framework came from, what each test actually asks, and how do5's goal coach enforces it.

Where it comes from

The SMART acronym first appears in George T. Doran's 1981 article "There's a S.M.A.R.T. way to write management's goals and objectives," in Management Review.¹ Doran's original letters were Specific, Measurable, Assignable, Realistic and Time-related, aimed at managers writing objectives for teams. The version in common use today — Specific, Measurable, Achievable, Relevant, Timely — is the one Harvard Health sets out for personal goals,² and it is the version do5 uses.

The five criteria

Harvard Health's framing is the clearest, and it is worth quoting the shape of each test rather than just the word.²

Specific. Clear, detailed, and tied to a meaningful outcome. Not "be more active" but "exercise 30 minutes, five days a week, so I have the stamina to travel."
Measurable. A number, a percentage, or an unmistakable finish line. "Lose weight" is not measurable; "lose 15 pounds" is.
Achievable. Grounded in what you can realistically do now — not an idealized version of you. The article's advice is to scale the target down rather than set yourself up to fail.
Relevant. It must matter to your life right now and have a real purpose. A goal set only to have a goal is the kind people abandon.
Timely. A specific deadline, with enough time to be safe and realistic — not 20 pounds in three weeks.

The same article adds two practices that are not in the acronym but matter as much: break big goals into smaller ones so progress is visible and can be celebrated, and write the goal down — a goal that exists only as an intention has no finish line to check against.

Why the structure matters more than the words

SMART is often treated as a checklist to run once and forget. Its real value is that it turns a wish into something that can be checked. "Get fit" cannot be scored; "finish the Brooklyn Half under two hours by 16 May" can be scored every day until then. The two criteria a goal is genuinely useless without are Measurable and Timely: without a finish line there is nothing to approach, and without a date there is no way to know whether today's effort was enough. Every other criterion refines the goal; those two make it a goal at all.

How do5 applies it

Goals are set in conversation, not in a form. do5's goal coach asks what you want, then asks — one question at a time, never a list — until it has a measurable finish line, a reason it matters, and a timeframe. Only then does it propose a plan.

A plan is stored as separate fields: the target, why it matters, the measure, the deadline, and what do5 should put on an ordinary weekday and weekend to move it. They are never collapsed into one sentence; the separation is what makes the goal checkable. The app cites this Harvard Health article by name in the coach's own instructions.

A proposal without a measure or a deadline is rejected — the code sends the coach back to ask. Achievable outranks ambition: if a target is unrealistic in the time available, the coach says so and proposes the realistic version; if you insist, it keeps your target and extends the deadline rather than quietly shrinking what you asked for.

Your goal then becomes the source of your priorities. The daily action you agreed is what usually appears as the day's green task, and the goal's score is counted in days — a day counts as done only when every task the goal produced that day was checked off.

Limits worth knowing

A SMART goal tells you where the finish line is; it does not protect the time to run toward it. That is the job of the other two methods: scarcity keeps the goal's work from being one item among forty, and the Eisenhower Matrix keeps urgent noise from burying it.
