Scrum Master Toolbox Podcast: Agile Storytelling from the Trenches Episode: Managing The Network of Promises in Lean Construction | Luca Cotta Ramusino
Host: Vasco Duarte
Release Date: June 19, 2025

Introduction

In this episode of the Scrum Master Toolbox Podcast, host Vasco Duarte engages in a profound conversation with Luca Cotta Ramusino, an expert in applying Lean and Agile methodologies within the construction industry. The discussion delves into the innovative integration of Agile retrospectives in construction projects, exploring how principles traditionally associated with software development can revolutionize construction management.

Agile Retrospectives in Construction Projects

Luca begins by addressing the unconventional application of Agile retrospectives in the construction sector. Drawing parallels from Scrum and the Toyota Production System (TPS), specifically the concept of Hansei (reflection or introspection), Luca emphasizes the necessity of regular reflection to foster continuous improvement.

Luca Cotta Ramusino [01:55]: "Basically, how can you improve what you're doing if you keep doing the same thing you've been doing?"

He highlights the challenges introduced by the COVID-19 pandemic, which necessitated remote collaboration and increased the importance of reflection without traditional face-to-face interactions. This led to the adoption of informal, daily reflections integrated into routine activities.

Reflect and Disinfect: An Innovative Retrospective Technique

One of the standout practices discussed is the Reflect and Disinfect method, coined by colleague Colin Milburgh. This technique seamlessly blends daily health protocols with reflective practice, ensuring that teams take a moment to introspect at the end of each working day.

Luca Cotta Ramusino [02:20]: "While you were disinfecting, you also had a chance to speak freely. And this was very, very, very informal."

The Reflect and Disinfect session is designed to be brief, lasting only about 15 minutes, and occurs naturally as workers conclude their day by putting away tools and sanitizing their hands. This informal setting encourages open communication without the pressure of formal meeting notes, enabling teams to discuss:

1. What to Continue: Celebrating successful practices.
2. What to Stop: Identifying ineffective methods detrimental to the project.
3. What to Start: Experimenting with new approaches to enhance productivity.

Daily Reflection: A Value-Rich Practice

Luca underscores the value of integrating daily reflections, a practice seldom emphasized in software circles where the pace often hinders the allocation of time for improvement.

Luca Cotta Ramusino [06:35]: "The ability of creating that daily reflection is really valuable."

He compares it to the software industry's tendency to postpone reflection, leading to inefficiencies that become ingrained until they require significant correction.

Key Metrics in Lean Construction: PPC and RNC

Transitioning to measurement, Luca introduces two pivotal metrics from the Last Planner Method, a collaborative planning approach in construction:

1. Percentage of Plan Complete (PPC):
   Measures the reliability of commitments by evaluating the percentage of planned tasks that are completed within the expected timeframe.

2. Reasons for Not Complete (RNC):
   Identifies the root causes behind incomplete tasks, allowing teams to address recurring issues systematically.

Luca Cotta Ramusino [08:17]: "It's on Tuesday. If you have completed that on Monday night. Okay. This is like a promise that two different teams make to one another."

He likens construction projects to a network of promises, where each commitment must be honored to ensure smooth progress. High PPC indicates reliable promises, while RNC provides insights into areas needing improvement.

Reliable Promises and Their Qualities

A central theme is the concept of reliable promises, foundational to effective collaboration in construction projects. Luca outlines the essential qualities that constitute a reliable promise:

1. Autonomy to Decline:
   Teams must have the ability to say no to unrealistic commitments.

2. Knowledgeable Parties:
   All involved parties should have a clear understanding of their responsibilities and the tasks at hand.

3. Capability to Deliver:
   Ensuring that teams have the necessary resources and means to fulfill their promises.

4. Shared Understanding of "Done":
   Establishing a mutual agreement on what constitutes task completion, preventing misunderstandings and ensuring quality.

Luca Cotta Ramusino [13:37]: "A reliable promise has a number of identifiable qualities... Both parties have to agree on what done means to the point that we have two different statuses for work. One is done and we also have done done."

This dual-status system differentiates between mere completion and a consensus that the task meets all required standards, akin to Scrum's "Definition of Done."

Definition of Done vs. Done Done

Luca elaborates on the importance of distinguishing between "done" and "done done":

• Done:
  Indicates that a task has been completed from the perspective of the team executing the work.

• Done Done:
  Represents a collective agreement that the task meets all criteria and standards required by the receiving party.

Luca Cotta Ramusino [14:55]: "It's not done until it's done done."

This approach ensures that quality is not compromised and that all stakeholders share a unified understanding of task completion.

Insights and Conclusions

The episode provides valuable insights into how Agile practices, particularly retrospectives, can be effectively adapted beyond their traditional domains. By implementing daily reflections and robust metrics like PPC and RNC, construction teams can enhance their reliability and continuous improvement efforts. The emphasis on reliable promises and a clear definition of done fosters a culture of accountability and quality, essential for the successful execution of complex construction projects.

Luca’s experiences underscore the universality of Agile principles and their adaptability to various industries, demonstrating that the core values of reflection, collaboration, and continuous improvement are instrumental in driving project success.
