Lean principles 
Eliminate Waste 
Optimize The Whole 
Focus On Customers 
Energize Workers 
Learn First 
Deliver Fast 
Build Quality In 
Keep Getting Better 
(Mary and Tom Poppendiek)
Tip #1: Easy 
Identify waste
The Waste Snake
What you need 
Whiteboard/A3 Sheet 
Post-its 
Curious team
Tip #2: easy 
Ask “Why?”
Ask “Why?” 
Software is a liability 
Resolving problems with very little software is of 
great value
Let me tell you a story 
1965 - US Army: “We need a cost effective 
fighter jet that can reach speed of mach3” 
Many companies tried, one succeeded let me 
tell you a story
Thunderchief Vs Eagle
That means 
Refuse solutions to unknown problems 
understand what the real problem is (asking 
“why?”) and then resolve that (Gojko Adzic)
What you need 
Courage 
Trust 
Empathy 
Curious team
Tip #3: Medium 
See the whole
Have you ever seen this?
What’s the solution?
That means 
Focus on the full flow 
Remove barriers, collaborate, be cross 
functional, remove silo departments, whole 
team responsibility and accountability, fight 
suboptimization.
What you need 
Curious team 
Empathy 
No barriers 
No politics 
One goal, one direction
Tip #4: Difficult 
Have zero tolerance for 
defects
Bugs are waste 
The worst kind of waste! 
Don’t write them in the first place! 
Focus on prevention TDD/BDD 
Implement fast feedback loops
If a bug slips through 
Fix it immediately 
We don’t need to log categorize, sort, triage, 
asses, fight over BUGS 
We need to fix them so that our customers are 
happy 
A bug management tool is another backlog, 
ditch it, we’ve done it and we’re happy!
Collaborate and prevent
What you need 
Curious team 
Empathy 
No barriers 
No politics 
Passion for our craft
Tip #X: Easy 
Don’t ask for permission, 
beg for forgiveness!
What do these things have in 
common?
They were failures
What does this mean? 
The wrong answer is the right answer to a 
different question (Paul Sloane) 
Experiment, try new things, things you’ve never 
done before, accept failure and learn from it. 
Only people that don’t innovate never fail. 
You can only improve trying new things, you can 
only innovate trying new things, don’t be 
afraid of failure
So? 
Fail often 
Fail cheap 
How can I fail cheap? Prototyping, spiking, getting 
fast feedback, speaking to the customers, getting 
out of my building and speaking about my idea.
What you need 
Curious team 
Courage 
Desire to learn

predictable 
#NoEstimates

Editor's Notes

  1. We need a faster plane Why? We need to escape missiles from enemy migs Why? Because when we see them it is already too late Why do you see them too late? Because I can’t see down to my left and right and the missiles appear from there first Ah ok, maybe we might improve that giving you better visibility And if we are using any instrument the stabilizer kicks in and when it is in on it takes a second to reset to manual, too late to change direction Why do you need the stabilizer? So that for long trips piloting is easier Do you need it in combat? No Would you like to be able to disable it in combat? Yes!!! Speed was not the answer
