Brian P. Moran and Michael Lennington
Scope: Author profile for Brian P. Moran and Michael Lennington, built only from the Kindle highlights of The 12 Week Year. The method itself lives in The 12 Week Year: Execution Cycle.

Co-authors of The 12 Week Year: Get More Done in 12 Weeks than Others Do in 12 Months. The source file contains only the highlights, no biographical material, so this profile is limited to what the book argues. Their stated quest: “to unlock the secret to helping individuals and organizations perform at their best and live the life they are truly capable of.”
The 12 Week Year
Thesis: the barrier to high performance is execution, not knowledge, and the calendar year is the wrong planning unit because it breeds complacency.
“The barrier standing between you and the life you are capable of living is a lack of consistent execution.”
Structure of the system:
- Three principles: Accountability, Commitment, Greatness in the Moment.
- Five disciplines: Vision, Planning, Process Control, Measurement, Time Use.
- Process control tools: a weekly plan, a weekly execution score, and a Weekly Accountability Meeting (WAM) with a peer group of two to four.
Concept articles:
- The 12 Week Year: Execution Cycle: the 12-week horizon, vision-to-week cascade, emotional cycle of change.
- Lag Indicators: the 85 percent benchmark and plan-versus-execution diagnosis.
- Time Blocking: strategic, buffer and breakout blocks.
- Accountability Above the Line: their ownership definition, “Accountability is not consequences; it’s ownership.”

Same family as the 4DX authors (Wildly Important Goals), John Doerr’s OKRs (OKRs) and Keller and Papasan’s focus argument. They also recommend Switch, The Power of Habit and Feel the Fear and Do It Anyway on barriers to change.
