The 12-week execution glossary
Every term in the system, defined in plain language — from lead measures to the 13th week. Each entry links to the guide chapter where the concept lives.
12 Week Year
The 12 Week Year is a goal-execution methodology from the book by Brian P. Moran and Michael Lennington that replaces annual planning with 12-week cycles. Each cycle carries one to three measurable goals, weekly tactics, and a weekly execution score, so every week is accountable and deadlines stay close enough to drive action.
12-Week Goal
A 12-week goal is a specific, measurable outcome you commit to achieving within one 12-week cycle. Effective 12-week goals are few (one to three per cycle), stated as results rather than activities, and paired with a lag measure — a number that will be verifiably true or false on the final day.
Accountability Partner
An accountability partner is a person who sees your weekly execution score and expects you to explain it — a peer, coach, or colleague running their own 12-week plan. The arrangement works through visibility, not enforcement: knowing someone will look at Friday's number measurably changes what you do on Tuesday.
Breakout Block
A breakout block is at least three hours scheduled away from work entirely — no email, no tasks — used for rest and perspective. The 12 Week Year prescribes it because sustained 85% execution requires recovery; without deliberate time off, intensity decays into the low-grade busyness that blocks were meant to prevent.
Buffer Block
A buffer block is a scheduled 30–60 minute window, once or twice a day, for handling email, messages, and small administrative tasks in batches. By giving low-value-but-necessary work a contained home, buffer blocks stop it from leaking across the day and interrupting the strategic blocks where real progress happens.
Daily Execution Score
A daily execution score is the percentage of a day's planned tactics completed, scored at day's end rather than waiting for Friday. It tightens the feedback loop from a week to a day, useful for daily-cadence tactics and for catching a drifting week by Tuesday instead of discovering it in the weekly review.
Execution System
An execution system is the set of structures — goals, tactics, scoring, reviews, and accountability — that turns intentions into consistent weekly action. The 12 Week Year's central claim is that most people fail on execution, not ideas or knowledge, so a system that measures execution outperforms better plans without one.
Lag Measure
A lag measure is a number that tracks the result you ultimately want — revenue closed, pounds lost, a book finished. It confirms success but arrives too late to act on, which is why every lag measure needs supporting lead measures. In a 12-week plan, each goal is defined by one lag measure.
Lead Measure
A lead measure is a number that tracks the actions you control — calls made, workouts completed, words written — rather than the results those actions produce. Lead measures are predictive and influenceable: move them and the lag measure follows. In a 12-week plan, tactics are the lead measures you score every week.
Performance Time
Performance time is The 12 Week Year's time-blocking system: structuring the week around three recurring block types — strategic blocks for deep work on tactics, buffer blocks for email and admin, and breakout blocks for genuine time off. It ensures the plan gets calendar space instead of competing with whatever arrives each day.
Quarterly Sprint
A quarterly sprint is a focused 12-week execution cycle treated as a complete planning period rather than a quarter of a larger year. It has its own goals, weekly tactics, scoring, and end-of-cycle review. The short horizon creates urgency: there is no later half of the year to absorb procrastination.
Strategic Block
A strategic block is a recurring three-hour appointment with your most important work: uninterrupted, single-focus time reserved for the tactics that drive your 12-week goals. The 12 Week Year recommends at least one per week, protected like a client meeting — nothing else gets scheduled over it.
Tactic
A tactic is a specific, recurring action that drives a 12-week goal — the weekly to-do that produces the result. Good tactics pass a binary test: at week's end you can answer 'did I do it?' with yes or no. Tactics are what you score, so vague ones break the whole system.
The 13th Week
The 13th week is the transition week between 12-week cycles, used to close out the finished quarter: score the cycle, review what worked and what failed, celebrate the win, rest briefly, and plan the next 12 weeks. It prevents the momentum gap that otherwise opens between one cycle and the next.
The 85% Rule
The 85% rule is The 12 Week Year's execution benchmark: complete at least 85% of your planned weekly tactics and your goals become highly likely, even without perfection. It reframes success around consistency rather than intensity — a sustained 85% beats alternating weeks of 100% and 40%, and it builds in slack for real life.
Vision Statement
A vision statement is a written description of the life and work you want three-to-five years out, plus the longer-term aspiration behind it. In the 12 Week Year system it sits above every plan: 12-week goals are chosen because they visibly advance the vision, which supplies motivation when execution gets hard.
Weekly Accountability Meeting (WAM)
A Weekly Accountability Meeting (WAM) is a short, standing meeting — typically 15–30 minutes — where individuals report their weekly execution scores, what worked, and what they will do differently. The agenda is scores, not status. Peer visibility, not management pressure, is the mechanism: people execute better when someone will see the number.
Weekly Execution Score
The weekly execution score is the percentage of planned tactics you actually completed in a week: completed divided by planned, times 100. It measures execution, not results — you control it completely. The 12 Week Year's benchmark is 85%: sustain that most weeks and goal achievement becomes highly predictable.
Weekly Review
A weekly review is a 15–20 minute session, usually Friday or Monday, where you score the finished week, log what blocked any missed tactics, and commit to next week's tactic list. It is the solo equivalent of the accountability meeting and the single habit that keeps a 12-week plan alive.
Weekly Scorecard
A weekly scorecard is the list of a week's planned tactics with a checkbox for each, producing a weekly execution score: completed tactics divided by planned tactics. It converts a plan from a document into a measurement instrument, making execution visible week by week instead of discoverable only at quarter's end.
