Counting how many teams run Agile ceremonies is measuring activity, not improvement. Elisabeth Hendrickson and Joel Tosi call that “change theater,” and it’s one of the illusions their new book Signals & Levers is built to dismantle. In Episode 550 of Lean Blog Interviews, I talk with Elisabeth and Joel about Signals & Levers: Systems Thinking Tools to Unblock Software Delivery (IT Revolution, September 2026). The book applies systems thinking, Deming, Shewhart, Argyris, and Donella Meadows to software delivery, but most of the conversation applies to any organization trying to improve. In this conversation: 🔵 The three illusions that travel together: predictability, progress, and control 🔵 Why “running open loop” means changing things without ever checking whether the change worked 🔵 How organizations accidentally create latency by separating strategy from execution and skills from each other 🔵 Why Joel introduced process behavior charts (Shewhart charts) to software teams, and what he wanted to stop arguing about 🔵 Why story points are an opinion, cycle time is a fact, and doing math on an opinion still gives you an opinion 🔵 Why a Chris Argyris “Model One” organization scores itself high on psychological safety surveys while behaving otherwise 🔵 Why you can’t fix fear by telling people to be brave Chapters: 00:00 Meet Elisabeth Hendrickson and Joel Tosi 04:30 Origin stories and a Toyota supplier lesson 11:50 Systems thinking applied to software 14:07 Three illusions: predictability, progress, control 17:32 Every change is a hypothesis 20:16 Open loop vs closed loop 25:24 Change theater and measuring activity 28:15 Latency that organizations create by accident 36:21 Process behavior charts and variability 44:11 Why story points are opinions 47:17 Psychological safety surveys that mislead 55:31 You can't fix fear by telling people to be brave 58:40 Everyone has levers About the guests: Elisabeth Hendrickson is the founder of Curious Duck Digital Laboratory, where she advises and coaches technology leaders. She was previously VP of R&D at Pivotal, leading about 170 engineers, product managers, and designers, and she is the author of Explore It!

Change Theater and the Illusion of Progress | Elisabeth Hendrickson & Joel Tosi
Psychological safety doesn’t come from a tidy formula. Leaders build it through specific behaviors, repeated over time. They can practice those behaviors, watch what happens, and adjust. My new course, Leading with Psychological Safety, is now available from TKMG Academy. It’s for senior leaders, frontline managers, continuous improvement professionals, consultants, educators, and anyone who wants a culture where people speak up to improve how work gets done. The course covers: 🔵 What psychological safety is, and common misconceptions 🔵 The four stages of psychological safety (from Timothy R. Clark) 🔵 Two reasons people stay silent: fear and futility 🔵 Four leadership behaviors that build it: Model, Encourage, Enable, and Reward 🔵 How to assess progress 13 lessons, about an hour total. Also available in Spanish. Available now. Learn more and purchase here: https://tkmgacademy.com/courses/leading-with-psychological-safety/
Psychological Safety Isn’t a Formula. It’s Leadership Behavior.
Tyler McBroom asked to reschedule a 10:30 PM call about partnering with Tony Robbins, then spent three years trying to get it back. When the offer finally came, he understood why the wait may have protected his firm. What you’ll hear: 🔵 The rescheduling request that turned into three years of follow-up 🔵 What Tyler sent every month while he waited, and the silence that came back 🔵 How his firm grew from four people to 24 before the partnership arrived 🔵 Why landing it the first time might have caused the firm to implode 🔵 The math on doubling your price and losing half your clients 🔵 The “grin test” for any tax deduction you’d have to defend in an audit Tyler McBroom, CPA, MBA, is the CEO of TRM CPA and the author of Cash Flow and Grow.
