In this Mob Mentality Show episode, we dive into the journey of Jeff “Cheezy” Morgan, a coach in Continuous Delivery (CD) and lean thinking. Known for his role in advocating for CD within companies, Jeff shares how his experiences with software development and his recent shift into the café business have shaped his philosophy on people and just-in-time. This discussion explores how Jeff’s approach to Agile and CD evolved, his journey into Extreme Programming (XP), and how mob programming impacted his perspective on teamwork and Continuous Integration (CI).  **Jeff’s Agile and CD Journey** We start with Jeff’s introduction to Agile, discussing the early days of his career when dev practices didn’t include CD and the impact of adopting CD in high-stakes projects like Y2K. Jeff describes how learning from Thoughtworks influenced his views on XP and CD, and how he became an advocate, eventually taking CD to different organizations. He also shares what it was like discussing with Woody Zuill and Llewellyn Falco and reflects on the transformative role mob programming has played in his career. **From Pairing to Mobbing**   For Jeff, mob programming was not initially appealing, but over time it became his preferred approach for helping teams. We explore how mobbing enhances CI, tightens communication, and fosters collective learning. Jeff explains how mobbing enables "just-in-time" discussions that align teams on what to build and how it allows real-time feedback on other team members’ learning. Jeff also examines the transition from pairing to mobbing, the challenges of mob programming with CI/CD, and why mobbing helps him “get the whole system in the room” for tackling complex problems. **Quality Without QA?**   We dive into the controversial idea of achieving high quality without traditional Quality Assurance (QA). Jeff opens up about years spent wrestling with the role of QA in Agile/CD environments and shares experiments with “test-infected” developers—who took full ownership of quality. He reflects on the pitfalls of relying on “heavyweight” traditional QA processes and automated tests, which often create lean waste, add handoffs, and introduce brittle, flakey tests. Jeff and hosts Austin and Chris discuss whether “shift left” is merely a shift away from QA, the Deming Red Bead experiment’s relevance, and whether there’s a happy journey for QA professionals on CD teams. **Applying Lean to Cafés**   Outside the tech world, Jeff has found a second passion—running cafés. We discuss how owning two cafés influenced Jeff’s perspective on Lean thinking and Agile principles. From supply chain issues during COVID to needing backup suppliers, Jeff discusses if “just-in-time” challenges in the café world mirror software development. He shares valuable insights about hiring, managing consistent delivery, and applying Lean principles to run a resilient business. Additionally, Jeff and Chris exchange stories on chip shortages and if Lean can help address real-world supply chain issues. **More from Jeff**   Finally, we tackle some big questions: What does DevOps mean in today’s Agile world? Should “DevOps” be responsible for shielding organizations from developers? How does Test-Driven Development (TDD) factor into DevOps scripts, and can mobbing help break down silos that traditionally separated devs, ops, and QA? Join us for this wide-ranging conversation with Jeff “Cheezy” Morgan to uncover actionable insights for anyone involved in Agile, CD, DevOps, or Lean. Whether you're in software, QA, or running a small business, this episode is packed with valuable takeaways on quality, learning, and resilience.  Video and Show Notes: https://youtu.be/OJ5d6qLIQRY   

In this episode of the Mob Mentality Show, join us as we delve into "The Discovery of Ignorance in Product Development: Time for a Smarter Way to Deliver Customer Value" with our special guest, Gary Cohen. Drawing on his rich experience across diverse sectors—from government agencies to startups—Gary brings a wealth of insight into optimizing product discovery and delivery for true customer impact.  ### **Key Topics Explored: The Product Discovery and Delivery Intersection** Even if a team is familiar with the 80/20 rule (e.g., where 80% of features go unused), how does it determine the right 20% to deliver? Gary shares strategies to tackle this challenge, advocating for a shift from traditional roadmap fixation to embracing dynamic, continuous discovery that keeps customer value at the forefront. Together, we examine the effectiveness of "strict" roadmap discipline (the practice of adhering to set timelines and objectives) and if it becomes a barrier to true innovation and customer value. We also briefly touch on the FAST framework and its relevance to product discovery, emphasizing how collective discovery through mobbing allows teams to stay closer to evolving customer needs.  ### **The Role of GenAI in Modern Product Development** Is AI is reshaping product discovery? We explore how GenAI can be a collaborative asset for mobs, not only for code development but also for bringing value by uncovering insights into customer behavior and streamlining feature prioritization. We compare "introverted" AI and "extroverted" AI in mob environments and discusses how developing refined AI inquiry skills is key to leveraging AI’s full potential. From training mobs in nuanced prompt engineering to using AI to help drive a more lean delivery, we share ways to maximize AI's impact while maintaining expert human oversight.  ### **Bootstrapping Pair and Mob Programming in Individualist Cultures** Transitioning to collaborative programming environments such as pair or mob programming can be challenging, especially in workplaces with a culture of individuality. We offer quick tips on how to bootstrap these methods, from creating a safe space for experimentation to aligning incentives via a peer promotion process. By using context sensitive analogies, how can we influence others in the org to consider jumping into the highly effective world of mob programming? ### **Unpacking Behavioral Expectations: A Smarter Approach to Product Decisions** Beyond the technical, we look at the behavioral side of product monitoring, asking, “What responses do we expect from our users?” Gary emphasizes the importance of behavioral prediction in discovery, cautioning against information bias and providing ways to gauge responses to feature experiments in real-time. We highlight the importance of monitoring usage data and what it reveals about customer engagement—whether a feature elicits a “wow” or a mere “meh.” ### **Takeaways for Product Managers, Engineers, and Innovators** From continuous discovery to leveraging the art of AI prompting, Gary Cohen’s insights provide actionable advice for product managers, developers, and cross-functional teams who are ready to rethink their approach to product development and delivery. Whether you're looking to reduce waste, increase customer value, or integrate mob programming and GenAI into your workflow, this episode offers some experiments to try in your journey to achieve product success.

In this exciting episode of the Mob Mentality Show, we are joined by Kyle Griffin Aretae to dive deep into the nuances of Test-Driven Development (TDD) and the crucial concept of "Goal-Centricity" in Agile practices. Kyle breaks down why TDD is so much more than just "test first" and challenges common misconceptions about this widely used development practice. If you're a software developer, Agile enthusiast, or just someone looking to refine your team's development processes, this episode is packed with insights you won't want to miss. We explore why treating TDD as merely writing tests first misses the larger picture and how adopting a broader, more progressive approach can help your team build better, more maintainable software. Kyle shares his thoughts on the primary value proposition of TDD, focusing on **fast feedback loops** and the **refactor step** at least every 5 minutes. He explains how smaller, healthier TDD cycles allow developers to stay nimble and avoid the trap of feedback loops that last 30 minutes or more. Thus, when fast feedback loops with constant refactoring are in place as the foundation, then the "test first" aspect of TDD really shines.  Kyle also sheds light on common pitfalls, such as the misunderstanding of what it means to "do TDD" when developers claim they have 8 unit tests on 50,000 lines of code. We discusses the difference between **Cargo Cult XP (Extreme Programming)** and the real deal, as well as the critical role of **decoupling code** so tests can run in 5 seconds or less.  A key takeaway from this episode is the impact of **social programming**, TDD, and **CI/CD (Continuous Integration/Continuous Delivery) pipelines**. We explain the importance of the "Pipeline First" principle when writing new code. We then dive into Kyle's most controversial take on TDD: the idea that creating a **mini-plan** (a rough roadmap of what to do next) before writing tests might actually be more beneficial than strictly adhering to "test first." This, Kyle argues, leads to more robust code when integrated into strong social programming practices. We also touch on the application of **Maslow's Hierarchy of Needs** to TDD and the importance of satisfying basic development needs (like fast feedback and clean code) before tackling more complex issues. The episode continues with a discussion on the intersection of **Goal-Centricity** and Agile. Kyle questions whether Agile methods are effective without first agreeing on a clear goal. We explore scenarios where goals are unclear or where methods are imposed without understanding the desired outcomes. Kyle shares a fascinating example of a code freeze during "Black Friday" and the unintended consequences of such decisions. We also reference a powerful quote by **Deming**, "A goal without method is cruel," explaining how the opposite can be just as problematic. Throughout the conversation, we dive into the importance of aligning goals between management and development teams, avoiding the common trap of blindly delivering fixed requirements for bonuses, and how real Agile success comes from alignment on solving customer problems, not just ticking off tasks. Kyle emphasizes the need to start with a clear understanding of what you're trying to achieve before applying any method, whether it's Scrum or TDD. Don't miss out on this thought-provoking episode filled with actionable insights on TDD, Agile, and effective software development.
