The 100 Day Plan Is a Lie. Here's What Actually Works for new CEOs

A new CEO's hundred day plan sounds smart. The research says it's mostly fiction.

In this solo episode, Jason Baumgarten traces the hundred day myth back to its real origin (FDR's 1933 Congress, not leadership research) and explains why boards keep asking a question that sets new leaders up to fail. Drawing on research into CEO transitions, he lays out five separate "clocks" (strategic, socialization, team, cultural, and performance) that all move at different speeds, and why compressing them into one sprint produces theatrical reorgs, rushed strategy, and boards misjudging leaders in both directions.

Key takeaways:

The hundred day plan comes from politics, not leadership researchShareholders reported it takes 19 months for a CEO's decisions to show up in share priceA leader's first year of results is often driven by their predecessor's work, not their ownFive clocks run at different speeds: strategic, socialization, team, cultural, and performanceOnboarding language wrongly frames a CEO as someone who should assimilate into the systemBoards should separate diagnostic milestones from impact milestonesLeaders should replace urgency with sequencing, and negotiate time horizons explicitly with the boardReal transitions take closer to two to three years, not 100 daysConnect with Jason: https://www.linkedin.com/in/jasonbaumgarten/
