We do card walls really well.


But they’re only the tip of the iceberg.

The mass of the system is below

the surface, unseen.

Kanban isn’t about card walls.

It’s about safe, evolutionary change.


How do you help teams for whom

Kanban is simply card walls?

Great idea. But how do you launch it?

Our system exhibits this aspect barely, if at all

Our system is somewhat capable of exhibiting this aspect

Our system exhibits this aspect convincingly, for the most part

Our system departs from this only very exceptionally, understanding and managing the consequence

It is such a positive indication about how much Asynchrony cares about people and how to help them be a part of successful and continually improving teams.

Visibility leads to conversation, which leads to understanding, which leads to change. But someone needs to start the conversation.


The New Three Questions

Scrum Kanban •  What have you

completed since the last meeting?

•  What do you plan to complete by the next meeting?

•  What is getting in your way?

•  How can we improve flow today?

•  What is blocked and why? •  Where are bottlenecks

forming?

David Anderson’s cartoon FTW!


Not as easy as it looked.

?


What do you do with blockers?


Getting Started

•  Talk with your teammates about the experiment •  Define “block” for your team •  Minimally instrument your kanban system to gather

data, including the block reason and duration


Getting started


Blocker Analysis


Blocker Analysis


Observations

•  Internal blockers caused 20 days worth of delay •  External blockers caused 147 days worth of delay •  The biggest blocker cluster accounted for 86 days of

delay


You have a 75% chance each week of creating a blocker that costs you an average of 29

days. Is this acceptable to you?


Another Example


Another Example


Other Learning

•  It’s important to understand your commitment point. •  Depending on how you want to address blockers,

you might choose to sort them differently (e.g., contact person rather than source).

•  Be diligent about collecting data


Collaboration and Balance


Standup Meetings

Retrospectives

Operations Reviews

Our three main feedback loops.





… most valuable about this meeting is the fact that it's a venue for sharing experimental practices and judging how well they worked or didn't

-‐Team lead


Operations reviews without division or unit

context are a bit like asking “How are things on

your mountain?”


Sometimes, we need help beyond

retrospectives to reach the peak.


So we’re still trying to

understand the best

way to use operations

reviews in our context.


Start at the Start: Interns!


Sharing Experiences
