These posts explore psychological safety through a Lean leadership lens—connecting daily behaviors, system design, mistake response, and respect for people. Drawing from healthcare, manufacturing, aviation, and executive leadership, this archive focuses on how leaders create (or destroy) the conditions for honest dialogue, problem solving, and sustainable improvement.

TL;DR: PDCA is meant to be a learning cycle, but in fear-based cultures it becomes PDCYA–Plan, Do, Cover Your A**. When leaders punish mistakes, people stop learning and start protecting themselves. Psychological safety turns PDCA back into real improvement. Lean…

A lot of companies “define” their values by gathering the leadership team in a room, tossing around words like “integrity” or “excellence,” and selecting the ones that sound good on a slide. Then they hope–maybe even expect–that the rest of…
