Tip #1: Easy Identify waste

The Waste Snake

What you need Whiteboard/A3 Sheet Post-its Curious team

Tip #2: easy Ask “Why?”

Software is a liability Resolving problems with very little software is of great value

Let me tell you a story 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
