What is a mistake?
A mistake is a decision or judgement that led to a negative
outcome, which could have been prevented with the
knowledge and resources available at the time.
Mistakes are a
learning opportunity
But a mistake is just like

a lump of ore
Post mortem
• Bring together people
from all affected
departments

• Collect a timeline of
events

• Find the root cause

• Define actions
Requirements for effective learning
• Transparency

• Finding the root cause

• Trust

• Respect
Anti-patterns
• Hiding mistakes

• Blame game

• The Arc of Escalation

• Cowardice
Anti-Pattern:

Hiding mistakes
• CEO Disease

• Wasted learning opportunity

• Sets the wrong example

• Financial bonus often leads to hiding mistakes
Pattern:
Proactive communication
• Be open about the
failure

• Now have a post-
mortem

• Talk about what was
learned
Anti-Pattern:

Blaming
• People get defensive

• Aggression and fear
disable learning

• Root cause gets
hidden
Pattern:

Accepting
• A post mortem is NOT
a performance review

• Focus on events, not
on (groups of) people

• Prime directive
The Prime Directive
Regardless of what we discover, we understand and truly
believe that everyone did the best job they could, given
what they knew at the time, their skills and abilities, the
resources available, and the situation at hand.

--Norm Kerth, Project Retrospectives: A Handbook for Team
Reviews
Anti-Pattern:

Arc of Escalation
• You play Chinese
Whispers

• You force a blame
game

• You destroy trust
Interlude: An Experiment
2 — 4 — 8
What’s my rule?
a1 < a2 < a3
Pattern:

Talk to your peers
• Be aware of
confirmation bias

• They are nice guys,
really!

• Try to switch
perspectives
Anti-Pattern:

Cowardice
• Time wasted on
formalities

• No one wants to be
responsible

• Cause: punishing or
firing people who
screw up
Pattern:
Embrace Failure
• You are a ninja!

• You are a scientist!

• You are an adventurer!
Predicting Failure

aka Pre mortem
• Gather groups of
people from different
departments

• Start with a
catastrophic outcome

• Have fun

• Rinse. Repeat.
