Mistakes happen. That’s just a fact. But what really matters is how organizations deal with them. Do they punish people for messing up, or do they see mistakes as learning opportunities? That’s where the Zero Blame culture comes in.

Why Zero Blame Works

Harvard professor Amy Edmondson found that the best teams weren’t the ones making fewer mistakes, they were the ones talking about them more. Why? Because they felt safe enough to admit when something went wrong. And when people feel safe, they work better, learn faster, and improve things instead of hiding problems.

The Zero Blame approach helps companies:
Encourage innovation: People take more chances and try new ideas.
Build better teamwork: Less finger-pointing, more problem-solving.
Fix problems faster: Because mistakes aren’t swept under the rug.

From Blame to Learning: The Blame Game

One way to start building a Zero Blame culture is with The Blame Game, a tool that helps teams talk about mistakes in a structured, non-judgmental way. It’s a card-based activity where participants look at real or hypothetical mistakes and place them on a spectrum of reasons for failure.

Amy Edmondson’s failure spectrum identifies nine levels of failure, from blameworthy to praiseworthy. Understanding where a mistake falls on this spectrum helps teams react appropriately instead of just blaming someone. Here’s how it works:

The Spectrum of Reasons for Failure

Blameworthy mistakes (to be avoided)

1. Deviance: Someone deliberately ignores rules or procedures.
2. Inattention: A mistake caused by carelessness or distraction.
3. Lack of ability:  The person did not have the right skills or knowledge.

Neutral failure (room for improvement)

4. Process inadequacy:  The system or process itself is flawed.
5. Task challenge:  The task was too difficult given the resources available.
6. Process complexity:  Mistakes happened because the system was too complicated.

Praiseworthy failure (learning opportunities!)

7. Uncertainty:  A failure caused by dealing with unknown factors.
8. Experimentation:  Trying something new that didn’t work out.
9. Exploration:  A bold attempt to push boundaries and discover something new.

Most organizations assume mistakes happen because of carelessness or incompetence. But The Blame Game helps teams see the bigger picture, many failures are actually caused by broken systems, unclear processes, or a lack of experimentation.

What Leaders Can Do

A Zero Blame culture starts at the top. Leaders need to:

  • Be honest about their own mistakes. Sharing vulnerabilities and how they handled it gives a method for others as well.
  • Create a safe space for employees to speak up, experiment and learn. Talk openly about mistakes in meetings.
  • Make it clear which mistakes are okay (like experimenting) and which need to be avoided or fixed. Reward smart risks, even if they don’t work out.

Companies That Get It Right

Big names like Google, Toyota, and Netflix use this mindset. Toyota even has a system where workers can stop production if they see a problem—without getting in trouble. That way, mistakes are caught early, and things keep improving. And when working with uncertainty, we have a local example, Tazz , which makes a case for experimentation to reduce ineffective, conventional solutions.

At the end of the day, every company makes mistakes.

The question is: Do you blame people, or do you learn together with them?

 The answer could decide whether your business grows or stays stuck.
