Food for Agile Thought #511: AI Bubble, Perfect Product Roadmap, Inversion as Mental Model, Scaling Culture?

TL; DR: AI Bubble — Food for Agile Thought #511

Welcome to the 511th edition of the Food for Agile Thought newsletter, shared with 40,483 peers. This week, Cedric Chin outlines the Vaughn Tan Rule: keep human judgment central while using AI for synthesis, retrieval, transformation, and speed across grading, feedback, research, coding, scheduling, and discovery. Janna Bastow reframes roadmaps as living prototypes tied to strategy and impact. Itamar Gilad urges AI-enabled, evidence-guided discovery over artifact output. Azeem Azhar, with Nathan Warren, proposes five gauges for assessing the AI bubble risk, while Alex Heath interviews Bret Taylor on agentic apps, voice, and outcome-based models.

Next, Teresa Torres and Petra Wille show how real AI products emerge from prompt decomposition, orchestration, observability, and rigorous evals with cross-functional tradeoffs. Jing Hu highlights MIT’s AI Risk Repository and urges post-deployment focus and concrete failure modes. Mike Fisher explains scaling culture through codified values and rituals, and Kent Beck frames programming deflation and the scarcity of judgment. Also, Gergely Orosz and Laura Tacho share how 18 firms measure AI’s engineering impact.

Lastly, Maarten Dalmijn urges context over dogma by adapting or breaking Scrum rules when outcomes suffer. Paul Boag promotes functional, task-driven personas via lightweight AI workflows, and Emma Webster argues AI accelerates speed but not craft, calling for curiosity, intuition, taste, and intention. Also, Shane Hastie interviews Thanos Diacakis on attacking one bottleneck, limiting WIP, and investing 20 to 30 percent in improvement. Finally, Aaron Chatterji and coauthors chart ChatGPT’s global, rising nonwork adoption and decision-support value.

🏆 The Tip of the Week

Cedric Chin (via Commonplace): How to Use AI Without Becoming Stupid

Cedric Chin introduces the Vaughn Tan Rule: Do not outsource subjective value judgments to AI unless you clearly state and accept the tradeoff. Preserve human meaning-making while using AI for synthesis, retrieval, transformation, and speed. Practical examples span grading, feedback workflows, research comparisons, coding, scheduling, and product discovery.

🎯 Product

Janna Bastow (via ProdPad): The Problem with the Perfect Roadmap

Janna Bastow says polished roadmaps waste time, hide uncertainty, and block adaptation. She suggests treating them as living prototypes that show bets, gaps, and desired outcomes, invite debate, and tie initiatives to strategy and measurable impact.

Teresa Torres and Petra Wille: 🎙 Building AI Products

Teresa Torres and Petra Wille explain how product teams build real AI products, emphasizing prompt decomposition, orchestration, observability, rigorous evals, and cross-functional collaboration while weighing risk, maintenance costs, and when AI truly solves customer problems rather than casual ChatGPT use.

Itamar Gilad: AI and Product Management: Becoming More Evidence-Guided

Itamar Gilad argues AI’s real value for PMs is enabling evidence-guided discovery, augmenting analysis, modeling, and goal setting. At the same time, humans lead communication and context, so culture shifts from output and artifacts to outcomes and validated learning.

Paul Boag (via Smashing Magazine): Functional Personas With AI: A Lean, Practical Workflow

Paul Boag advocates functional, task-driven personas over demographics, using lightweight AI workflows to synthesize messy inputs, segment by needs, validate lightly, and keep personas living tools that guide design, content, and conversion decisions.

🧠 Artificial Intelligence

Azeem Azhar: Is AI a bubble? A Practical Framework to Answer the Biggest Question in Tech

Azeem Azhar and Nathan Warren argue that AI is a boom, not a bubble yet. They offer five gauges to monitor economic strain, industry strain, revenue growth, valuation heat, and funding quality, which can help identify the AI bubble risk.

Bret Taylor (via The Verge): Sierra CEO Bret Taylor on why the AI bubble feels like the dotcom boom

Alex Heath captures Bret Taylor’s view that today’s AI surge mirrors the dotcom era: exuberant investment, inevitable failures, yet durable winners as agentic applications mature, voice grows, and outcome-based business models align real value.

Jing Hu: All You Need For AI Risks

Jing Hu spotlights MIT’s living AI Risk Repository cataloging 1,600 failures, urging teams to ignore hype, focus on post-deployment risks, pick one killer domain, shortlist concrete failure modes, and tell actionable stories to drive accountability.

(via Figma): How to Harness Skills That AI Can’t Automate

Emma Webster argues AI boosts speed but not craft, urging teams to cultivate curiosity, intuition, taste, and intention, use design systems as guardrails, and steer AI toward emotionally resonant, high-quality outcomes instead of merely functional prototypes.

Customer Voice: “The AI for Agilists course is an absolute essential for anyone working in the field! If you want to keep up with the organizations and teams you support, this course will equip you with not only knowledge of how to leverage AI for your work as an Agilist but will also give you endless tips & tricks to get better results and outcomes. I thoroughly enjoyed the course content, structure, and activities. Working in teams to apply what we learned was the best part, as it led to great insights for how I could apply what I was learning. After the first day on the course, I already walked away with many things I could apply at work. I highly recommend this course to anyone looking to better understand AI in general, but more specifically, how to leverage AI for Agility.” (Lauren Tuffs, Change Leader | Business Agility.)

➿ Agile & Leadership

Maarten Dalmijn: On Inversion, Rules and Purpose

Maarten Dalmijn argues rules serve a purpose, not obedience. Challenge dogma, apply inversion, and adapt Scrum pragmatically. When a rule hinders outcomes, consider amending or breaking it to favor context, experimentation, and understanding instead.

Mike Fisher: How Culture Scales (or Doesn’t)

Mike Fisher argues that growth stresses culture and proximity-based norms break as teams scale. Leaders must codify values, design durable rituals, use stories, and build decision frameworks so culture strengthens with size and remains adaptive.

Kent Beck: Programming Deflation: When Code Gets Cheaper Every Day

Kent Beck argues programming is in deflation: AI makes code cheap, amplifying both substitution and Jevons effects. Use commodity tools, but invest in judgment, taste, systems thinking, and integration—the new scarcity that wins regardless of headcount outcomes.

📯 Join the AI for Agile Practitioners Survey — Why We Need Your Insights

After analyzing dozens of “AI will transform agile” articles, I’ve found a troubling pattern: They’re written by AI enthusiasts who’ve never run a Sprint, not by practitioners dealing with the messy reality of AI integration.

The result? A dangerous gap between AI hype and Agile’s reality on the ground, leading to misguided implementations across our industry.

As someone who has documented Agile anti-patterns for years, I recognize this pattern. When we let others define our practices without practitioner input, we get cargo cult implementations that miss the essence of what makes Agile work.

👉 The AI for Agile Practitioners Survey is our opportunity to establish the definitive, practitioner-driven understanding of AI’s actual impact on our field—before the consultants and tool vendors do it for us.

🛠 Concepts, Practices, Tools & Measuring

Shane Hastie (via InfoQ): 🎙 Why Software Development Sucks And 7 Mental Models To Help Fix It

Shane Hastie interviews Thanos Diacakis, who argues teams should tackle one bottleneck at a time, limit work in process, balance features with quality and debt, automate feedback to ship faster, and invest 20 to 30 percent in improvement.

Gergely Orosz and Laura Tacho: How tech companies measure the impact of AI on software development

Gergely Orosz and Laura Tacho detail how 18 companies measure AI’s impact on engineering using core delivery, quality, and DevEx metrics plus AI usage, costs, and cohorts to balance speed, reliability, maintainability, and real outcomes.

(via NBER): 📈 How People Use ChatGPT

Aaron Chatterji et al. analyze ChatGPT adoption through July 2025, finding usage by about 10 percent of the world’s adult population, with nonwork use rising, work led by writing, and decision support driving value.
