Mob Anti-Patterns Explained: Fly on the Wall, Runaway Driver, and More with James Herr

The Mob Mentality Show

Show Notes

In this episode of the Mob Mentality Show, we sit down with James Herr from Flexion to explore the dark side of mob programming — the anti-patterns that quietly erode collaboration, learning, and flow in your team.From the “Fly on the Wall” who silently observes but never joins in, to the “Runaway Driver” who takes control and goes rogue, and the “Knee-High Navigator” who dictates every keystroke, these relatable scenarios shine a light on what can go wrong during mob or ensemble programming sessions — and, we share some potential experiments ideas to address them.James shares real-world insights from years of ensemble experience, walking through the subtle behaviors and team dynamics that lead to these anti-patterns. The discussion moves beyond surface-level symptoms to uncover psychological safety, learning theft, and communication habits that make or break mobbing success.You’ll learn:- What causes common mob programming anti-patterns — and how to recognize them early- Practical techniques to help newcomers integrate smoothly without being overwhelmed- How to use “strong-style” collaboration and mini-retros to restore balance in a team- When to “let it cook” vs. when to intervene to prevent runaway drivers- How to cultivate high-level navigation and reduce micromanagement in coding sessions- Why “white-glove” onboarding for visitors and new mobbers accelerates learning and trust- How naming patterns improves team reflection, vocabulary, and psychological safetyThis episode dives deep into the human side of technical collaboration, blending agile principles, systems thinking, and lived experience from teams practicing mob and ensemble programming every day.Whether you’re a developer, product owner, engineering leader, or agile coach, you’ll walk away with practical strategies to identify and correct these patterns — before they derail your team’s effectiveness.Video and Show Notes: https://youtu.be/NxLor73Rgds

In this Mob Mentality Show episode, we sit down with Elizabeth Hendrickson and Joel Tossi for a fascinating deep dive into systems thinking, context, and variability. Drawing from the core ideas in their book, Signals and Levers, this conversation explores how mapping systems can transform organizational alignment, shift how leaders invest their resources, and expose the hidden dependencies across seemingly disconnected departments. Elizabeth and Joel share practical insights into how causal loop diagramming, managing side effects, and looking closely at structural constraints can help teams escape the traps of rigid delivery cadences. They discuss how a shared systemic perspective shifts conversations away from isolated department goals and toward true organizational adaptability and collaboration. We dig into: • How systems thinking and causal loop diagramming can map the hidden intersections between software, hardware, sales, and marketing. • The way analyzing system delays and constraints can dramatically shift executive investment strategy to focus where it’s needed most. • Why understanding systemic variability is more important for overall organizational health than merely forcing a predictable delivery cadence. • Moving beyond superficial agile practices to build true, data-driven alignment between cross-functional business leaders. • Real-world stories from the field of immersive learning, dojos, and designing organizations built to adapt organically. Whether you are a software crafter, a product leader, or an executive interested in systems design, this episode offers a practical guide to stepping back, seeing the bigger picture, and finding the true levers that drive high-performing organizations.

In this Mob Mentality Show episode, Chris Lucian sits down with Diana Larsen — co-author of Lead Without Blame, Five Rules for Accelerated Learning, and Agile Retrospectives — to explore what leadership looks like when your team is made of both humans and AI agents. Diana, who came into agile "through the XP door" in the late 90s, argues that a team of some number of humans plus some number of agents is still a complex adaptive system: it has a container, an identity, differences among its players, and exchanges that let it collaborate. The practices we built for human teams — retrospectives, chartering, liftoffs, checkpoints — still apply, if we're intentional about bringing them along. Diana shares her "your agent is your mirror" idea (inspired by the book Your Dog Is Your Mirror): LLMs reflect the behavior they were trained on, and the way we talk to them shapes us too. She types please and thank you to her agents — not for them, but to retain her own humanity. Chris connects this to Theory X vs. Theory Y prompting, his agents.md files with single and double loop learning built in, and his experiments using a frontier model to build a deterministic TDD state-machine MCP server that keeps a less capable model honest — like a senior developer building a process for a junior. The conversation then turns to mobbing with agents and the leadership challenges of this moment. Chris describes how his mobs use "weighing the ox" (wisdom of the crowd) prompting, collaborative prompting, and rotating across four machines, and why the 20-minute agent runtime is a key threshold for context switching. He argues mobbing is more valuable than ever because the typing was never the hard part. Together they discuss the diffusion of innovation, why "Agile is dead" gets declared at every chasm crossing, token maxing as Goodhart's Law taken to its extreme, the Red Queen hypothesis, why no one should have been laid off over AI, and a broken hiring pipeline where a "beautiful" new-grad resume from three years ago now gets 6 callbacks out of 700 applications.

In this Mob Mentality Show episode, Chris Lucian sits down with Woody Zuill and James Herr to explore one of the most pressing questions in software teaming today: when AI is writing the code and your team is barely touching the keyboard, where does mob programming fit in? Rather than pushing collaboration aside, James and Woody argue that AI is exposing long-standing bottlenecks more clearly than ever — and that the ensemble is more important now, not less. They share the "AIM Mobbing" perspective they are developing, showing how AI and software teaming unlock the full ensemble by finally removing code as a barrier to participation.

Chris Lucian and Austin Chadwick discuss all things #agile and product development from a #MobProgramming perspective. What if you could decompose every agile method down to its essential building blocks and recombine them for your own specific context? In this episode, Chris and Austin are joined by Aria Omidvar to explore the HEXI method — a framework-agnostic approach to understanding and applying agile, lean, and software craftsmanship practices through physical hexagon objects and collective sense-making. Aria shares his journey from software craftsmanship and clean code, through Scrum and XP, to discovering Dave Snowden's HEXI method and building his own independent "Hexiverse" — a modular knowledge map that spans Software Teaming, Extreme Programming, Kanban, Modern Synthesis, the Agile Manifesto, and more. He unpacks how breaking methods into reusable hexagonal pieces allows teams (and individuals) to see the connections between ideas, surface what is missing, and navigate the overwhelming landscape of agile methods without falling into method wars.

In this Mob Mentality Show episode, we join James Herr and Woody Zuill for a one-of-a-kind session James calls the "Hot Sauce Ensemble" — mob programming a video game from scratch in the Godot engine using AI, while eating escalating hot sauces every three-minute rotation. Fair warning to podcast listeners: this episode has a strong YouTube component. If things start sounding chaotic and spicy, that's because they are — jump over to YouTube to see what's happening on screen. James set up the session with Claude Code in VS Code (backed by Amazon Bedrock) and a blank Godot project containing only one asset: a hot sauce sprite generated by ChatGPT. From there, the mob navigated an AI coding agent through a real-time game build — adding player movement, landing explosions, and physics-based bell pepper enemies that scatter when stomped. The enemies were bell peppers specifically because Chris despises them. The hero is hot sauce. The logic is sound. Along the way, James introduced the "plate spinning" technique: opening multiple AI agents in parallel terminals so one prompt cooks while the mob drives another, keeping momentum even when AI responses run long.
