Let's be clear on one thing.

Agile/Lean does not solve your problems!

It brings your problems to the surface and has mechanisms built in to encourage you to solve

them one by one.

Your problems are there by design

What you have now is the result of your actions and decisions up until now.

We are our habits!

All the brilliant people working on at least one thing each and passes it downstream when done with it's part

The feedback loop is our friend

Efficiency vs Effectiveness

Effectiveness (Complex) Reaching the best possible result with a given effort

Efficiency (Obvious/Complicated) Reaching a given result with the minimal effort.

Resource efficiency vs flow efficiency

Work Elapsed calendar time

A 10h 100 days

A 15h 10 days

No way from resource to flow efficiency

Economics of iterative delivery

• Guess 3 digits (000-999) • Guess costs 1 unit per digit • Correct guess of all 3 digits gives 3000 units

• Traditional Guess all commits to guess all 3 digits at once • Iterative Guess 1 digit at a time and decides if they want

to commit to guessing the next one based on the result
