Money

...the root of all Evil.
I have

of banks.
Andrew Jackson
John, money and his father
John, money and his father
When John turned 25 his father gave him $30,000.
His Dad taught him that money makes money.
And...
“How much will I have in 40 years?”
Your money and your bank
Do banks have an answer?
Oh Yes.
You guessed!
“It depends!”

“Let’s do Scrum!”
And so we started our journey!
Round #1
Round #1
We were smartasses, hence need no help…
Translating… no time for learning! Too much to do 
After “deeply” study ...
Round #1
“Scrum is very simple!”
We ended up with…
Anarchic Scrum
Act… without thinking.
Sense… without data.
Respond… without awareness.
Anarchic Scrum

But someone else didn’t…
Round #2

“This is too much turbulent.”

  97. 97. Outcomes: Emergence on solutions. Boost team morale and confidence. Excellence on engineering practices. Dramatically improve client’s trust. #2 Working Software Mindset Lessons: Working Software is not always what user values the most. Value capitalization impacts tremendously on compound effect.
  98. 98. Outcomes: Increase client’s engagement. Amplify Learning & See the Whole. Improve all communication channels. Learn from the client, “fast & furious”. #3 Scrum On a Lean Client Lessons: Customer Collaboration has huge compound value. It is easy to slow down iteration pace, hence, a balance must be pursued.
  99. 99. Outcomes: Boost on team morale! Clarity on team capacity! Development steady pace regained. #4 Pulling The Sprint Lessons: Overflow blocks Iteration. Overflow blocks Interaction. Overflow blocks everything. Seeing the flow is amazing!

  108. 108. Compound Knowledge Does it make sense to you?
  109. 109. Going back to Lean and Scrum
  110. 110. Going back to Lean & Scrum D P C A S P R E R Lean (PDCA) Done by Quality Circles Focus on Efficiency Decrease Cost! ↑ Cycles ≫ ↓ Cost Scrum (PSR2 E) Done by Scrum Teams Focus on Effectiveness Deliver Value! ↑ Cycles ≫ ↑ Value
  111. 111. Going back to Lean & Scrum Lean Scrum Main Goal Reduce Cost Deliver Value Focus On Efficiency Effectiveness Teams: QC Circles Scrum Teams Cycle: PDCA Sprint (PSE2 E) Deliverables: Process Improvements Product Increments
  112. 112. Going back to Lean & Scrum Lean & Scrum are made by Thinkers! PDCAs and Sprints are empirical iteration processes! Learn by doing! And only by learning a lot… …your organizational knowledge is increased!
  113. 113. Going back to Lean & Scrum Both Lean & Scrum have deliverables! And only by delivering your process/product is improved! You can deliver with an high or low frequency! You can also deliver high our low value improvements! This is what we call the Improvement rate (per delivery).
  114. 114. Going back to Lean & Scrum The Improvement rate is, therefore, a function of: Team’s iteration (learning) cycle, the shorter the better. Team’s delivery (compounding) cycle, the shorter the better. Team’s interaction frequency & quality with the customer. Team’s (compounded) knowledge over time 
  115. 115. Compound interest is the 8th wonder of the world. Albert Einstein
  116. 116. A Simple Example
  117. 117. A Simple Example Your 2 ecommerce sites’ monthly sales are $30,000/site. You want to improve it  You assemble 2 Scrum Teams, 1 per site… … and gave them a KPI to improve over 40 weeks: Gross Transaction Value (GTV)
  118. 118. A Simple Example Team A decides: Iteration cycle = 2 weeks Delivery cycle = once every iteration
  119. 119. A Simple Example Team B decides: Iteration cycle = 1 week Delivery cycle = once every iteration
  120. 120. 403020100 211,200 30,000 Team Improvement rate Delivery cycle Multiplier A 5% / deliverable 1 every 2 weeks 2,7x B 5% / deliverable 1 every 1 week 7,0x 79,599
  121. 121. Summing up Our experiments on the field, highlighted these 2 properties of an Agile Ecosystem, hence, no matter what you do or how you do it, just: Iterate & Interact to unleash… The Power of I(n)teration
