The document outlines lessons learned over 20 years since the introduction of value stream mapping (VSM) and its application in workflow design. It emphasizes the importance of translating future-state maps into actionable steps while acknowledging the uncertainties involved in implementation. The authors advocate for scientific thinking and continuous improvement, leveraging Toyota kata practices to effectively navigate toward defined future goals.

this SlideShare is for you

3. 2019 is the 20th Anniversary
of the Book Learning to See
In 1999, LTS kicked off worldwide
interest in Value Stream Mapping.
VSM has become the tool for
analyzing & designing work flows
at the door-to-door system level, and
LTS is a widely-used instruction manual.

4. What Have We Learned
Since Learning to Map?

5. A Lot of VSM Information
Has Been About How to Do VS Mapping
A different issue is not how to do
better mapping, but rather ... what do
you do with a future-state map?
5
How do you make what your map depicts real??

6. A significant area of learning for us has
been how to turn future-state VS maps
into reality, rather than wallpaper.

7. A future-state map provides a
high-level picture of an imagined
material and information flow

8. Then What?
New Ways
of Working
Once you’ve drawn a future-state map how do you effectively
handle the effort to move from current to future-state?

9. We convert our imagined future into a
list of implementation actions. Ironically
these action-item lists are made at the
point of maximum uncertainty about
how the implementation will actually go.
Problem #1:
An action list is only a
prediction, and a poor
one at that

10. A value stream design involves multiple
departments, processes and people.
It’s more complicated than modifying a single process.
Problem #2:

11. So Much Can (and will) Go Wrong

What Do You Do?
Here’s Nassim Nicholas Taleb on Dealing with Uncertainty
Outperformance arises
from optionality rather
than intelligence.*
Translation: Instead of trying to know in advance what is
going to happen, position yourself in such a way that you
have options to test. The advantage of optionality is that
as the world grows increasingly difficult to predict, you
can thrive in spite of not knowing the future.

13. "Let'stryitandsee"
It’s Scientific Thinking!
Source: Toyota Kata Practice Guide 13
What you learn in one step can
influence what you do in the next step

14. Scientific Thinking is Like
Navigating with a Compass
Scientific thinking may be the best means we
have for navigating through complex, dynamic,
unpredictable territory toward challenging goals
such as a future-state value stream design
You’ve defined a direction, but
the path to your future state,
and even what your future
state ends up looking like, is
not entirely predictable.

15. “We place the highest value on actual
implementation and taking action. There
are many things one doesn’t understand
and therefore we ask them why don’t
you just go ahead and take action: try
to do something? You realize how little
you know and you face your own failures
and redo it again and at the second trial
you realize another mistake or another
thing you didn’t like so you can redo it
once again. So by constant improvement
or, should I say, the improvement based
upon action, one can rise to the higher
level of practice and knowledge.”
-- Fujio Cho, former President, Toyota Motor Company
(as quoted in The Toyota Way)
In 2004 The Toyota Way
Described the Approach

16. In 2009 Toyota Kata
Gave Us a Way to Practice It
The Improvement Kata and
Coaching Kata gave us practical
scientific-thinking practice
routines for navigating
the way to our
desired future.

sometimes even called
a “Challenge Map.”
It’s a Great Match

20. It’s just like what we found at Toyota
Everyone in an organization doesn’t do VSM,
but everyone benefits from practicing Toyota Kata
Setting direction with
VSM is the responsibility
of a few people
Practicing the Improvement

involves everyone 20

team scientific-thinking skills for moving there
