DESCRIPTION
We have to stop adopting defined processes (or methodologies as they known in the IT business). Instead we need to look to adopt a new style of management that encourages an adaptive capability to emerge in our organizations. This talk will look at Bruce Lee‘s rejection of patterned styles of Chinese Martial Arts and emergence of his Jeet Kune Do approach and compare it to the emergence of the Kanban Method. The talk will illustrate how to use fitness criteria metrics aligned to customer desires to manage an organization that is continually evolving its workflows to improve service delivery and customer satisfaction.TRANSCRIPT

Bruce Lee’s Journey in Martial Arts
[email protected] @lkuceo Copyright Lean Kanban Inc.
Bruce Lee rejected traditional teaching and styles of Chinese martial arts
[email protected] @lkuceo Copyright Lean Kanban Inc.
Snake
Monkey
Mantis
Tiger
Kung Fu Panda simplified the art to only four styles
[email protected] @lkuceo Copyright Lean Kanban Inc.
There are in fact very many styles…

“Dry land swimming” provides a false sense of capability
[email protected] @lkuceo Copyright Lean Kanban Inc.
Lee wanted to start from first principles and core concepts
*Apparently still called the Five Ways, there are actually now six **with the later inclusion of SAA**The fact that The Five Ways has six elements is evidence of evolution in action***Incorporated core ideas such as "center line" and single fluid motion from Wing Chun and parrying from Epee Fencing********Not a Chinese Martial Art and hence evidence of "no limitation as limitation"
Five* Ways of Attack***• Single Direct Attack (SDA)• Attack By Combination (ABC)• Progressive Indirect Attack
(PIA)• (Hand) Immobilization Attack
(HIA)• Attack by Drawing (ABD)• Single Angle Attack (SAA)

Lee’s approach still needed a name
[email protected] @lkuceo Copyright Lean Kanban Inc.
Jeet Kune Do
Using no way as way
Having no limitation as limitation
[email protected] @lkuceo Copyright Lean Kanban Inc.
Jeet Kune Do encourages development of a uniquely personal style
"absorb that which is useful“
discard the remainder

Training with an opponent provides the core feedback loop to drive adaptation

The Kanban Method…

Start with what you do now
[email protected] @lkuceo Copyright Lean Kanban Inc.
Fitness criteria are metrics that measure observable external outcomes
[email protected] @lkuceo Copyright Lean Kanban Inc.
Net Promoter Score is a Fitness Evaluator but is it the only metric we need?
Steve Denning
[email protected] @lkuceo Copyright Lean Kanban Inc.
Net Promoter Score is a way of evaluating customer satisfaction
[email protected] @lkuceo Copyright Lean Kanban Inc.
The problem with Net Promoter Score is that it doesn’t tell you what to do!
[email protected] @lkuceo Copyright Lean Kanban Inc.
Can we be smarter by using better fitness criteria than NPS?

ComparingKanban with Jeet Kune Do
[email protected] @lkuceo Copyright Lean Kanban Inc.
Jeet Kune Do is a framework for fighting
Center line
[email protected] @lkuceo Copyright Lean Kanban Inc.
Kanban is a framework for service-delivery management
[email protected] @lkuceo Copyright Lean Kanban Inc.
Kanban may be analogous to JKD for Service Delivery Management

The Kanban Method makes a business fitter for purpose
[email protected] @lkuceo Copyright Lean Kanban Inc.
Lean Startup is another evolutionary approach
Build-Measure-LearnCycle
[email protected] @lkuceo Copyright Lean Kanban Inc.
Lean Startup makes a product or service fitter for purpose
[email protected] @lkuceo Copyright Lean Kanban Inc.
Like Kanban, Lean Startup is a Pragmatic approach
[email protected] @lkuceo Copyright Lean Kanban Inc.
Businesses need to do both – be adaptable and adapt their products
[email protected] @lkuceo Copyright Lean Kanban Inc.
Together Kanban & Lean Startup bring the philosophy of JKD to modern creative
knowledge work industries
[email protected] @lkuceo Copyright Lean Kanban Inc.
The future of creative knowledge work should be inspired by Bruce Lee & JKD

Joe Cooper first blogged about the similarity in philosophy between the Kanban Method and the teachings of Bruce Lee. He coined the phrase “Kanban should be like water”.
The data on slides 45 & 46 was provided by Raymond Keating of CME Group.
This presentation was inspired by Alistair Cockburn’s blog post “The End of Methodology”. My approach to change was influenced by an observation from Peter Senge, “People do not resist change, they resist being changed!” “Safe-to-fail Experiment” is a term used by Dave Snowden in his Cynefin framework. Steve Denning proposed NPS as the only metric that matters in his book, “Radical Management.”
