Episode Title: Over-Commitment and Silence—The Deadly Duo Destroying Your Teams
Guest: Felipe Engineer-Manriquez
Host: Vasco Duarte
Date: January 27, 2026

Episode Overview

This episode dives into the twin anti-patterns of over-commitment and silence within Agile teams, especially in the context of construction and Lean/Agile practices. Host Vasco Duarte and guest Felipe Engineer-Manriquez explore how these patterns devastate team performance, the deeper systemic issues that drive them, and actionable interventions that Scrum Masters and team leaders can apply.

Key Discussion Points & Insights

The Transformative Power of “The Goal” and Theory of Constraints

[01:25 – 05:07]

• Book That Changed Felipe’s Practice:
  Felipe credits The Goal by Eliyahu Goldratt as the most transformative book in his Lean/Agile journey. He emphasizes the importance of the Theory of Constraints (TOC) for understanding and optimizing systems, both in construction and general Agile work.

• Quote:

  “The most transformative, the most amazing book that even sounds like a radio production is Eliyahu Goldratt’s The Goal... What you learn in that book is that it’s the slowest, slowest part of a process that actually governs and dictates where the improvement should happen.”
  — Felipe Engineer-Manriquez [02:16]

• Underutilized Practice:
  Felipe notes that many Scrum training programs skip over TOC and value stream mapping due to time constraints, leaving many certified Scrum Masters unfamiliar with these crucial concepts.

  “A lot of Scrum Masters that get credentialed never actually learn this.” [03:44]

The ‘Herbie’ Metaphor and Systems Thinking

[03:57 – 05:07]

• Use in Real Teams:
  Felipe brings “Herbie” (the slow hiker from The Goal) as a powerful metaphor for bottlenecks in teams: addressing the bottleneck benefits the whole system.

• Practical Application:
  Value stream mapping and reverse phase pull planning (as in the Last Planner System) help make bottlenecks and dependencies visible.

  “Once you start doing this… that’s a whole rabbit hole you could go into value stream mapping that I think is very underutilized by so many Scrum Masters.” [02:56]

Patterns of Self-Destruction: Over-Commitment & Silence

[05:07 – 11:28]

• Root Cause: Bad Systems, Not Bad People
  Self-destructive teams usually aren’t filled with “bad actors,” but with people crushed by broken systems. Workarounds proliferate to make up for process dysfunctions.

  “They don’t self destruct because they’re bad or you have bad characters … what I do see is people getting crushed in terribly bad systems and these people are doing all these workarounds to try to survive broken systems.”
  — Felipe [05:58]

• Case Story: The Consequences of Silence
  In construction, over-commitment is common: teams promise impossible things (e.g., scheduling a concrete pour without necessary prep). Low psychological safety leads to no one speaking up about obvious problems.

• Quote:

  “The biggest pattern of self destruction I saw was over commitment coupled with silence where people can’t bring up problems. Psychological safety was so low that people could not even say that the emperor has no clothes.”
  — Felipe [06:33]

• Systemic Impact:
  This combo leads to unrealistic deadlines, hidden blockers, and inevitable failures. Concrete team members “forced” to commit to undeliverable work because the system demands it.

Surfacing Problems: Asking Tough Questions

[07:39 – 11:28]

• Breaking the Pattern with Curious Questions:
  Felipe makes it a point to voice “obvious” dependencies (“Don’t you need X in place for Y?”), which can seem annoying but is necessary to expose unspoken risks and foster safety.

• Quote:

  “I just have to apologize. I’m just a simple dumb general contractor and I don’t understand this and I really don’t, I don’t understand why people need to overcommit. I mean I do understand—it’s because of the low psychological safety.”
  — Felipe [08:10]

• Reimagining Accountability:
  Real accountability comes only when people are empowered to say ‘no’ without fear. If they can’t say no, commitments are meaningless.

  “For real accountability, if people are not allowed to say no, then they actually can’t make a real promise.”
  — Felipe [09:31]

• Making Work Visible:
  Using “verb down” scrum cards (action-oriented phrasing) and tasks as a way to explicitly break down complexities and dependencies.

Silence Is Not Alignment

[10:10 – 10:54]

• The Executive Trap:
  Leaders often interpret silence as agreement; in reality, it signals fear or disengagement.

• Quote:

  “Silence is not alignment. And that’s a risk, especially for executives that come and make proclamations... When the team can’t like react and say yes, I’ll often raise my hand, say, excuse me, I didn’t see actually anybody agree to that.”
  — Felipe [10:12]

• Changing the Conversation:
  Pivotal question Felipe uses:

  “What would need to be true so that we could agree?”
  — Felipe [10:45]
  This reframes accountability and unlocks constructive team participation.

“Decision Hallucination”

[10:54 – 11:28]

• Related Insight (from prior guest):
  “Decision hallucination” is the act of making decisions based on invalid or out-of-date assumptions, a natural consequence of suppressed truth-telling within teams.

  “You are making decisions based on assumptions that are no longer true or were never true. So it’s a hallucination, right?”
  — Vasco Duarte [10:56]

Notable Quotes and Takeaways

• “Don’t you need this so that you can do that?” – Calling out dependencies is the first step in restoring rational planning and trust. [08:58]
• “If people are not allowed to say no, then they actually can’t make a real promise.” – True accountability demands psychological safety. [09:31]
• “Silence is not alignment.” – Don’t mistake lack of feedback for consent. [10:10]
• “What would need to be true so that we could agree?” – A simple, non-blaming phrase to surface blockers and empower teams. [10:45]
