The year in one word and one sentence
Write one word that describes the year. Then one sentence that explains it. 'Turbulent: we pivoted the product model in Q2, lost two key hires, and shipped the best feature we've ever built.' This forces a synthesis before the details. It also makes the board readable at a glance from the doorway.
Top three wins
The three things that most moved the company, team, or product forward this year. Not the three things that hit their metrics, the three things that actually mattered. These are the wins you'll reference in recruiting conversations, investor updates, and team history.
Top three misses
The three things that didn't work, and why. Be specific about the root cause: wrong bet, wrong execution, wrong timing, wrong people. Vague misses produce vague learnings. Specific misses produce specific improvements.
Learnings that will change how you operate
From the wins and misses: what will you do differently next year? Write two to four learnings that should actually change behavior, not platitudes, not things you already knew, not things you'll ignore. If a learning doesn't change anything, it's not a learning.
The one bet for next year
Write the single most important bet you're making for the coming year. Not the OKRs, the assumption the whole plan depends on. 'We bet that [X] is true, and we're going to spend the year proving it.' If this bet is wrong, what's the contingency?
