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
That means
Refuse solutions to unknown problemsunderstand what the real problem is (asking
“why?”) and then resolve that (Gojko Adzic)
That means
Focus on the full flow Remove barriers, collaborate, be cross
functional, remove silo departments, whole team responsibility and accountability, fight
suboptimization.
Bugs are waste
The worst kind of waste!Don’t write them in the first place!
Focus on prevention TDD/BDDImplement 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!
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.
