Scrum Master Toolbox Podcast: Agile Storytelling from the Trenches

Episode: BONUS: Never Stop Experimenting—Building a Culture of Continuous Discovery | Guest: Stavros Stavru
Release Date: June 21, 2025

Introduction to the Episode

In this special bonus episode of the Scrum Master Toolbox Podcast, host Vasco Duarte, a seasoned Agile Coach and Certified Scrum Master, welcomes Stavros Stavru, an esteemed expert in organizational transformations and agile coaching. Stavros shares insights from his book, Never Stop Experimenting, delving into the importance of fostering a culture of continuous discovery within Agile teams and organizations.

Stavros Stavru's Background and Book Overview

[01:11] Vasco Duarte:
"Stavros Stavru is a PhD in organizational transformations and a leading voice in agile coaching, leadership, and soft skills. He's the founder of EdTech Ventures, Aha Play, and the Carringers, has delivered over 800 trainings, and authored Never Stop Experimenting, a toolkit for continuous improvement."

[01:29] Stavros Stavru:
"Thank you, Vasco. I'm excited to discuss the importance of never ceasing to experiment within Agile frameworks."

Overview of Never Stop Experimenting: Stavros introduces his book as a response to the pervasive shift from exploration to exploitation within Agile environments. The book provides practical tools and mindsets to ensure that teams continue to discover and innovate, rather than solely focusing on delivery.

The Exploration vs. Exploitation Dilemma

[02:22] Stavros Stavru:
"I started the book with the Exploration-Exploitation dilemma: choosing between leveraging what we know (exploitation) and seeking new, potentially more valuable solutions (exploration)."

Stavros observes that many Agile teams initially embrace an exploratory mindset but gradually shift towards exploitation, prioritizing delivery over discovery. This shift often leads to a stagnation in innovation and experimentation.

Challenges in Maintaining a Culture of Experimentation

[04:50] Stavros Stavru:
"Before COVID, I noticed a trend where organizations emphasized experimentation and exploration in theory but rarely practiced it consistently. Teams would show initial sparks of discovery, only for it to fade over time."

[07:13] Host:
"Was it a lack of techniques or missing perspectives that hindered experimentation?"

[07:44] Stavros Stavru:
"The misalignment wasn’t just within teams but across the entire ecosystem, including management and stakeholders. Even motivated teams struggled to advocate for experimentation when the broader environment prioritized immediate delivery and tangible results."

Tools Introduced in the Book

Fatware Matrix

[12:56] Stavros Stavru:
"One key tool from my book is the Fatware Matrix. We visualized product features based on their value and maintenance cost. Plotting features on this matrix facilitated transparent discussions with product and business teams about which features to prioritize or eliminate."

[15:31] Host:
"The Fatware Matrix helps stakeholders understand both the value and the cost of maintaining features, similar to the KANO model for customer satisfaction."

[17:15] Stavros Stavru:
"This visualization led to actionable decisions, such as removing low-value features to streamline the product and allocate resources more effectively."

Never Stop Experimenting (NSE) Ratio

[19:13] Stavros Stavru:
"The NSE Ratio is a simple concept to determine when to introduce changes after a set number of repetitions. For instance, after every 10 estimates using poker planning, the 10th could employ a new estimating technique."

[20:10] Host:
"Like switching prioritization methods after a certain period to keep the process fresh and effective."

[21:37] Stavros Stavru:
"This ratio helps balance experimentation with consistency, preventing teams from deviating too frequently and maintaining direction."

Case Study: Implementing the Fatware Matrix

[12:56] Stavros Stavru:
"In one of the teams I worked with, the Fatware Matrix was utilized to plot features based on value and maintenance cost. This visual tool sparked meaningful discussions with the business development team, leading to the removal of non-essential features and a leaner, more maintainable product."

[15:35] Stavros Stavru:
"Accountability was established as the Fatware Matrix became integral to decision-making. Teams could clearly see the impact of their choices on lead times and resource allocation."

Building an Experimentation Culture

[23:10] Stavros Stavru:
"Start with yourself. Leaders must model experimentation by initiating and sharing their own experiments, demonstrating a commitment to learning and growth."

[25:56] Host:
"Leaders should openly discuss their failures to create a safe environment for experimentation."

[26:25] Stavros Stavru:
"The NSE Ratio aids in maintaining a structured approach to experimentation, ensuring that it remains purposeful and aligned with team goals."

Leadership's Role in Encouraging Experimentation

[23:10] Stavros Stavru:
"Leaders must set the stage for experimentation by embodying the mindset and encouraging their teams. It's crucial to align the entire ecosystem, including management and stakeholders, to support and sustain exploratory efforts."

[25:56] Stavros Stavru:
"At my startup, Haplay, we've run over 100 experiments. While most didn't yield the desired outcomes, the few that did were transformative. This experience has made it easier to advocate for continuous experimentation within the team."

Conclusion and Where to Learn More

[27:26] Host:
"Thank you, Stavros, for sharing these invaluable insights and stories. For those interested in Never Stop Experimenting, it's available on Amazon and other digital libraries. Stavros can also be reached at neverstopexperimenting.com and on LinkedIn for further discussions."

Key Takeaways

• Continuous Experimentation: Maintaining a balance between exploration (discovering new solutions) and exploitation (leveraging existing solutions) is crucial for sustained innovation in Agile teams.

• Tools for Implementation:

  • Fatware Matrix: A visual tool to assess and communicate the value versus maintenance cost of product features, aiding in decision-making.
  • NSE Ratio: A structured approach to introduce new techniques or changes after a defined number of repetitions, ensuring ongoing experimentation without losing focus.

• Leadership's Role: Leaders must embody and advocate for a culture of experimentation, aligning the entire organizational ecosystem to support and sustain exploratory initiatives.

• Safe-to-Fail Environment: Building a culture where failures from experiments are seen as learning opportunities fosters innovation and continuous improvement.

Notable Quotes

• Stavros Stavru [02:22]:
  "We often start with an exploration mindset, aiming to discover solutions, but over time, exploitation takes over, and we forget to experiment."

• Stavros Stavru [12:56]:
  "The Fatware Matrix became part of our decision-making process, providing clarity and accountability in feature management."

• Stavros Stavru [19:13]:
  "The NSE Ratio helps ground experimentation, ensuring it remains structured and aligned with our objectives."
