SMART Goals
SMART (George Doran, 1981: Specific, Measurable, Assignable, Realistic, Time-related) is the most widely taught goal formula in business, and for good reason: it compresses the two most robust findings in goal-setting research, specificity and measurability-for-feedback, into five letters anyone can remember.
It is not a rival to OKRs. It is a component already running inside them.
What it teaches, and what we carry
Every well-written Key Result is a SMART sentence: specific, measurable, owned, time-bound. Teams fluent in SMART arrive at KR-writing with the hygiene pre-installed, and target setting is SMART's calibration instinct done with more instruments. Doran himself made a point modern usage forgot: he never intended all five criteria to apply to every goal at every level. That nuance matches how the machinery divides the labour: the Objective carries meaning and ambition, the KRs carry the SMART discipline. Doran's own footnote is the earliest version of that division.
The pattern across the shelf
SMART is a sentence-level tool, and it is excellent at the sentence level. What every system on the shelf then adds, each in its own vocabulary, is the layer above the sentence: which goals, why these, at what rhythm, with what feedback. Hoshin Kanri adds direction and dialogue, EOS adds the weekly heartbeat, V2MOM adds narrative and obstacles, OKRs add alignment, cadence, confidence and grading. Pairing SMART sentences with a system around them is not a compromise; it is how the pieces were always meant to stack.
One watch-point, shared honestly
"Achievable", read inside systems where goals face consequences, quietly teaches pre-negotiation. The research behind aspirational targets shows a complementary path: keep targets calibrated and honest, label deliberate stretch, and judge quarters on evidence, so calibration and ambition stop being enemies. We wrote up the laundering mechanism in full in That Worked #3.
One line to keep: SMART writes a good sentence; a goal system decides which sentences are worth writing.

Are SMART goals and OKRs compatible? +
Completely: every well-written Key Result is a SMART sentence. SMART is the sentence-level discipline; OKRs add the system above it, which goals, at what rhythm, with what feedback and grading.
What is wrong with "Achievable"? +
Inside systems where goals face consequences, it quietly teaches pre-negotiation. The fix is consequence design: calibrated targets, labelled stretch, and quarters graded on judgment so honesty costs nothing.
Your teams already write SMART sentences. We install the system that decides which sentences are worth writing, and the grading that keeps them honest.
