In this episode, I engage with Dr. Bill Bellows in a deep dive into the application of W. Edwards Deming’s systems thinking in software development and DevOps. Dr. Bellows, a veteran in quality management and an expert in Deming’s principles, shares insights on variation, Taguchi loss functions, and the synthesis of parts in a system to highlight gaps in current industry metrics like DORA.

Key Topics:

1. Misconceptions About Managing Parts vs. Systems:
   • Dr. Bellows references Russell Ackoff’s assertion that managing individual parts optimally doesn’t guarantee an effective system. He relates this to the tendency in software and manufacturing to assess components in isolation rather than as part of a larger system.
2. The Role of Variation in Quality:
   • Building on Shewhart’s work, Dr. Bellows explains how statistical process control examines stability and variation within components. Taguchi’s insights are introduced to show how variation in individual parts impacts the whole system's functionality.
3. Applying Taguchi to Modern Metrics:
   • The conversation examines how DORA metrics, such as deployment frequency and mean time to recovery, serve as output measures but fail to address the underlying inputs driving these metrics. Dr. Bellows highlights the importance of understanding "failure" through operational definitions and its nuanced variations.
4. Systems Thinking in Feedback Loops:
   • Emphasizing tighter feedback loops, Dr. Bellows ties traditional Deming concepts to the promise of continuous improvement in DevOps. He advocates for a systemic view, where the interplay of individual variances contributes to collective outcomes.

Key Insights:

• Systems must be analyzed holistically to manage complexity and leverage opportunities effectively.
• Outputs like DORA metrics should inform adjustments to input characteristics rather than serve as the sole focus.
• Precision in defining failure and understanding its economic implications is critical to refining processes and delivering value.

In this short episode, I reconnect with Dr. Bill Bellows, a frequent guest and advocate for W. Edwards Deming's principles. The conversation focuses on reviving the In2:In Thinking Network, a nonprofit Dr. Bellows co-founded to improve how individuals and organizations work, learn, and think together. Dr. Bellows discusses the origins of the network and its 16-year legacy of bringing together diverse voices inspired by Deming, Russell Ackoff, and others to explore innovative ways of collaboration.

We also reveal exciting plans for a 2025 In2:In Thinking Network Conference in Santa Clarita, California. This event aims to merge communities from software development, systems thinking, and various industries to foster cross-pollination of ideas. The goal? An "oasis of sanity in a sea of madness," where passionate learners share experiences and challenge conventional approaches to problem-solving.

In this second installment of my conversation with Dr. David Woods, we continue our exploration of resilience engineering and complexity science, focusing on practical applications and actionable strategies. Building on the foundational concepts from part one, Dr. Woods offers deeper insights into how organizations can thrive in unpredictable environments by embracing resilience as a core competency.

We dive into the nuts and bolts of designing systems that can adapt and recover, emphasizing the importance of fostering collaboration, continuous learning, and feedback loops. Dr. Woods connects these practices to W. Edwards Deming’s teachings, particularly the interplay between profound knowledge and operational flexibility. Our conversation also underscores the significance of learning from near misses and small failures, treating them as opportunities to strengthen systems rather than vulnerabilities to hide.

Key highlights include:

• The Adaptive Cycle: Dr. Woods introduces a powerful framework for understanding how systems evolve and adapt over time, offering lessons for IT, healthcare, and manufacturing.
• Learning from Disruption: Examples of organizations that turned crises into growth opportunities by leveraging resilience principles.
• Operationalizing Resilience: How leaders can embed resilience thinking into daily operations through deliberate design and cultural shifts, echoing Deming’s focus on systems thinking and constancy of purpose.

This episode serves as a practical guide for anyone seeking to bridge theoretical concepts with real-world applications. Dr. Woods leaves us with actionable takeaways on how to lead and thrive in an era of constant change, making this a must-listen for leaders and practitioners alike.
