Understanding systems
Johanna Kollmann | @johannakoll | the lean event, Brighton
“A system is
a set of elements or parts
often classified as its function
or purpose.”
that is coherently organized and
inter-connected in a pattern or
structure
that produces a characteristic set of
behaviors,
Donella Meadows
“Systems-based thinking is the process of
understanding how things influence one
another. 
!
Then drawing on that knowledge to create
efficiencies of process, infrastructure and
communication.”
Abby Covert
Hard systems
Soft systems
!
You can’t “fix”problems with systems
thinking, instead there are “situations you
could improve”.
Peter Checkland
Systems exhibit purposeful behaviour over time.
Systems get ‘soft’, unpredictable once humans
are involved.

Tools for MODELING systems
Tools for MEASURING systems
Models are the starting point to look at
the situation, and see what change should
be introduced, and how.
Categorisation model:
precedes the data.
Sense-making model:
created from data;
the data precedes the framework.

“Only by building a model of customer
behaviour
and then showing our ability to use our
product or service to change it over time
can we establish real facts about the
validity of our vision.”

3 things to pay attention to in a system:
1) Stocks & Flows
2) Feedback loops
3) Delays
1)Stocks & Flows
inflow outflow
information
feedback, control
stock
2)Feedback loops
A feedback loop occurs when a change in something ultimately
comes back to cause a further change in the same thing.
Reinforcing Loop
(positive loop)
births/year population
Population
Growth
Balancing Loop
(negative or goal-seeking loop)
heat
Thermostat
temperature
target temperature

gap

Look at systems behaviour over time, rather than
focusing on single events.
!
Spot trends, and ask:
‣What came before?
‣What might happen next?
By the time you see what is going on in a
system, it has already happened - and you
are already a step behind.

Mental Model
System Model
Conceptual Model
We are not only explaining a system and
making it easy to use:
we are also shaping the role of the human
actors in the system.
For reference: Donella Meadows, http://donellameadows.org/archives/leverage-points-places-to-intervene-in-a-system/
Structure of information flows
‣How does information flow through the system?
‣What information is shown, how, and to whom?
‣Who can manipulate and control information?
For reference: Donella Meadows, http://donellameadows.org/archives/leverage-points-places-to-intervene-in-a-system/
Rules of the system
‣Constraints, social rules, rules about roles of actors in the system
‣Who can take which actions?
‣How can actors in the system engage?

How users understand the system,
and how they can engage with it
“When designers center around the user,
where do the needs and desires of the other
actors in the system go?
The lens of the user obscures the view
of the ecosystems it affects.”
!
“For users, this is what it means to be at the
center: to be unaware of anything outside
it.”

SKILLS
Russell L. Ackoff
The ‘Systems Age’ is about expansionism - all objects,
events and experiences are part of larger wholes.
!
Rather than focusing on ultimate events, it’s about
interrelated parts, about systems.
!
Instead of an analytic mode of thought, we
need a synthetic mode of thought.
Skills for the systems age:
1) The ability to think abductively.
2) The ability to synthesise information.
3) The ability to choose the right level of abstraction.
Abductive reasoning
Abductive logic allows for the creation of new knowledge and insight.
The conclusions from an abductive argument might turn out to be false, even if the
premises are true.
You make inferences (or educated guesses)based on an incomplete
set of information in order to come up with the most likely solution.

Ability to synthesise information
The process of drawing together concepts, ideas, objects and other qualitative data in
new configurations, or to create something entirely new.
!
Synthesis
‣typically deals with non-numeric data.
‣often undertaken towards the end of an analytic process as the reverse
of deconstruction.
‣can also form part of an exploration

Ability to choose the right level of abstraction
Models make complexity visible, tell a story, and allow us to create shared
understanding. Successful modeling requires abstraction.
!
‣define the boundaries
‣abstract with a purpose in mind
‣it’s about the process - not about deliverables
‣steward the process of abstraction
Skills for the systems age:
1) The ability to think abductively.
2) The ability to synthesise information.
3) The ability to choose the right level of abstraction.

need to navigate over the next
decade:
Going from designing for people to
designing with people at scale.”
