Agile: The Power of I(n)teration, an introduction :-) The Power of i(n)teration in Scrum: Cultural Flow, Compound Interest, Knowledge and Value. – Agile Manifesto and Agile Origins: Lean and Systems Thinking. – A powerful concept: Cultural Flow. – The Gap between Culture and Patterns and how to address it? Theory of Constraints (TOC) and some real life examples from the trenches. – Agile Values and Interaction & Iteration. Compound Interest. Another powerful concept: Compound Knowledge. An example. – Retrospective :-)

4. Agile Manifesto
Culture and Values
“At the core, I believe Agile Methodologies are really
about mushy stuff of values and culture.”

W. Edwards Deming
o Kaizen greatest influencer.
“I can say that Dr. Deming’ teachings were great
revelations to Japanese management which built
many Kaizen practices in Japan based on his principles.”
Masaaki Imai, Founder of Kaizen Institute.
o Lean Manufacturing “father”.
“Deming is the core of our management.”
Shoichiro Toyoda, Honorary Chairman and Director of Toyota.

6. Back to Origins
W. Edwards Deming
o SoPK – System of Profound Knowledge:
“There is no substitute for knowledge.”
“A system is a network of interdependent
components that work together to try to
accomplish the aim of the system.”
A system must be managed. It will not manage itself.”
“94% of problems in business are systems driven, only 6% are people driven.”

Everything is a system.
o System of development
o System of knowledge
o System of learning
o Complex ecoSystems
o Adaptive ecoSystems
o Thinking Systems

A System of everything? (probably just a theory…)

Every system has one or more flows.

o Financial Flow
o Informational Flow

13. What knowledge is available?
... from the community at large:
o Change Organizational Culture:
– Great thinkers’ literature: Edgar H. Schein, William E. Schneider, etc.
– Great coachers’ teachings: Michael Sahota, etc.
– Only an organizational effort can change a corporate Culture!
o Apply Patterns to Organizations:
– Patterns of Productive Software Organizations, Harrison, Coplien, 1996.
– Organizational Patterns of Agile Software Development, Harrison, Coplien, 2004.
– Scrum Pattern Community’s work in progress at http://www.scrumplop.org.
– Patterns are about thinking, caring and becoming, not about doing. Challenging!

16. The Gap
Drilling down:
o Change Organizational Values:
– Heavily dependent on the corporate culture: also requires an organizational effort.
– Anyway, we can work the Agile Values of a Scrum Team.
o Improve Social Behaviors:
– Difficult to master!
– Psychology and Sociology are two of the most complex fields of knowledge.
o “Fix” People’s Actions:
– Too time consuming.
– Most of the time, the corrective measures won’t last in time.

Constraint #1
On Behaviours
The only one that matters is
Team Collaboration.
▼
• Shared common goals.
• Boost on all communication levels.
• From group of individuals to a Team.
Constraint #2
On Values
The only one that matters is
delivering Working Software.
▼
• Emergence on solutions.
• Boost team morale and confidence.
• Excelence on engineering practices.
• Dramatically improve client’s trust.

23. Practice from the Field
Lessons learned:
o Elevate a Behavior like “Team Collaboration”:
– Helps storm a Team faster.
– Helps build a strong Team’s Identity.
o Elevate a Value like “Working Software”:
– Improves engineering practices and hence, confidence.
– Makes it possible to decrease the iteration cycle.
o Elevate a Value like “Customer Collaboration”:
– Increases dramatically the interaction frequency and quality.
– Bosts confidence on all Scrum participants across the ecosystem.

26. A Real Life Analogy
For left siders, let’s make a bank deposit:
o You have an principal of 1.000 Euros deposited on your bank.
o Your bank pays you an interest rate of 5%... 
o ... and compounds the interest each month (the period).
o How much money will you have after 12 months (periods)?
Period Principal Interest Future Value
0 (now) 1,000.00€ 1,000€ x 5% = 50,00€ 1,050.00€
1 1,050.00€ 1,050€ x 5% = 52.50€ 1,102.50€

Where:
o FV = Future (Potential) Product Business Value
o PV = Present Product Business Value
o r = Interaction Frequency Rate (%)
o n = Number of Iterations (Sprints)
Notes:
o Product Business Value ≠ Cash Flow from Operating Activities (CFO).
o Frequency = Number of occurrences of a repeating event / unit time.

An exercice:
o You have a product with a present business value of 10,000€.
o Your goal is to maximize the business value over the next year.
o You must interact with the client, either on low or high frequencies.
o You are free to choose the number of iterations (n) per year:
Iteration type iterations/year weeks/iteration hours/iteration
1 quarter 4 13 455
1 month 12 4 140
1 week 52 1 35

Our practice on “Cultural Flow”, applying constraints on its processes,
values and behaviours, highlighted these 2 properties of an Agile Ecosystem,
hence, no matter what you do or how you do it, just:
