What is the Kanban Method?


Kanban Method
A management & cultural approach to
improvement

View creative knowledge work as a set
of services
Encourages a management focus on
demand, business risks in, and capability
of each service to supply against, that
demand

Kanban Method
Uses visualization of invisible work and
virtual kanban systems

Installs evolutionary “DNA” in your
organization
Enables adaptability to respond
successfully to changes in your business
environment

Assessing Kanban
Implementations


Are we doing Kanban or not?
It isn’t a question of evaluating practice
usage but rather a question of intent?
Do you intend to use visualization & virtual
kanban systems as a core driver of a culture
of continuous improvement?
Do you view your organization as a network of
service-oriented workflows and seek to
improve the balance of capability against
demand?


If the intent is there, then the question
should be….
How Deep is your Kanban?

This raises the question, how do we put
a scale on the six axes?


Visualize
Work
Different Work Item Types
Workflow
Kanban Limits
Ready for pull ("done")
Blocking issues (special cause variations)
Capacity Allocation
Metrics-related aspects such as - lead
time, local cycle time, SLA target
• Inter-work item dependency (incl
hierarchical, parent-child dependency)
• Inter-workflow dependency
• Other risk dimensions - cost of delay (function
shape & order of magnitude), technical
risk, market risk
•

Limit WIP
• Deferred commitment & dynamic staff assignment (no WIP
limits) aka “last responsible moment”
• Proto-kanban
•
•
•

personal kanban
WIP limit per person
workflow with infinite limits on "done" queues

• Single workflow full pull system with WIP limits
• Multiple interdependent workflows with pull system

Standup Meeting

Disciplined conduct
and acts of leadership
lead to improvement
opportunities
Kaizen events happen
at after meetings


Improvement Kata

A mentor-mentee relationship
Usually (but not always) between a superior and a sub-ordinate
A focused discussion about system capability
Definition of target conditions
Discussion of counter-measures – actions taken to improve
capability


Operations Review

Meet monthly
Disciplined review of
demand and capability
for each kanban system
Provides system of

Kaizen events suggested

Improve collaboratively, evolve
experimentally (using models & scientific method)
• Evidence of local process evolution - changes to
workflow, policies, WIP limits
• Evidence of increasing depth of Kanban implementation on
other 5 practices
• Evidence that process evolution was model-driven - use
of metrics, identification of bottlenecks,
common/special cause variation,
transaction/coordination costs, other models not
specified in current literature
• Evidence of process or management policy evolution as a
result of mentor-mentee relationship
• Evidence of inter-workflow process or management
policy evolution as a result of operations review

Scaling Kanban

first principles around a service
provided
Scale out in a service-oriented fashion
Do not attempt to design a grand
solution at enterprise scale
The Kanban Kata are essential!
Allow a better system of systems to
emerge over time

to adopt a relative assessment model

Relative model usage
Pioneered by Pawel Brodzinski
The relative model is used with the
Improvement Kata to help drive a specific
local improvement under supervision of a
coach
Avoids concerns of a “CMMI levels” style
model for Kanban and pursuit of practice
adoption for the sake of it
IMO, requires an expert coach with deep
knowledge of Kanban (and other concepts) to
drive it.

Pawel Brodzinski,
http://blog.brodzinski.com/wp-content/uploads/kanban-radar-chart-6.png


Absolute model adoption
The absolute model is gaining traction with
larger organization such as space & defense
and public sector in USA, Canada and Sweden.
Provides a clear framework to guide deep
Kanban adoption. Allows wider audience to
understand why their coach is steering them in
a direction.
Helps management to adopt appropriate
expectations of outcomes based on appraised
depth

Acknowledgements

Hakan Forss of Avega Group in Stockholm has been instrumental in
defining the Kanban Kata and evangelizing its importance as part of a
Kaizen culture. He also challenged the incremental sequence of
practice adoption and catalyzed the discussion that led directly to
adoption of the multi-dimensional depth of Kanban assessment
framework.
Pawel Brodzinski has led the healthy debate on relative versus
absolute assessment.
