Before the day
Frame

About thirty minutes

A short look at systems thinking.

Six practical tools to preview before your upcoming class. Each one has a short clip, a plain-language summary, and one question to hold onto.

On the day, we will use these ideas on a live case and on your own work. No revision needed; just move through it once.

Before the tools

Frame: Systems Thinking

Why systems thinking?

Because many work problems are not isolated events. They are produced by patterns, relationships, structures, and assumptions that keep interacting.

A short orientation.

In everyday work, it is natural to respond to what is most visible: a late submission, a missed target, a tense meeting, a quiet stakeholder, or a decision that did not land well.

Systems thinking helps us slow down and look at what keeps producing the visible event. It asks how people, incentives, routines, information flows, relationships, and beliefs are connected.

This matters because effort alone can sometimes leave the pattern unchanged. A team can work harder, communicate more, or add more checks, but still get the same result if the underlying system keeps pulling people back into the same behaviour.

The goal of this preview is not to turn you into a systems expert before class. It is to give you shared language for noticing patterns, asking better questions, and examining your own thinking before acting.

See the pattern. Move beyond "what happened?" toward "what keeps happening?"
Look for leverage. Find places where a small shift may change the recurring result.
Work with others better. Make room for different views of the same system.

Source note. This framing draws on learning-organisation and systems-thinking work associated with Peter Senge and Donella Meadows: look beyond events to the structures, feedback, and mental models that shape recurring outcomes.

Hold this question

As you move through the tools, notice one work issue where the visible problem may be only the surface.

One of six

Tool: Levels Perspective

Levels Perspective

Look at the same situation from different depths: events, patterns, structures, and mental models.

Watch for

Notice where Lucy and Ethel put in more effort, and what part of the work system is actually setting the pace.

I Love Lucy — chocolate factory. Two workers cannot keep up with a belt going too fast. They try harder. The belt wins.

Then connect it to

The iceberg gives names to the deeper levels under the visible event. Use it to look beneath "they need to work harder".

The systems iceberg. The same idea, drawn out simply: what you see is only the top.

Open on YouTube ↗

So here is the idea.

The clip is funny because effort is not the missing ingredient. The belt speed, the work design, and the expectations around the work are shaping the outcome.

Levels Perspective helps you avoid staying only at the event level. A late report, a tired team, or a low score may sit on top of repeated patterns, work structures, incentives, and beliefs about what is normal or possible.

The move is to ask a calmer question: not "who is the problem?", but "which level is producing this pattern?"

Source note. This uses the systems-thinking "iceberg" view: events sit above patterns, structures, and mental models. It is closely related to Peter Senge's learning-organization work and Donella Meadows' writing on leverage points in systems.

Before you move on

Think of a problem at work that keeps coming back. Which level have you mostly been working at?

Tool: Creative Tension

Creative Tension

Hold the gap between current reality and the result you care about, long enough for the gap to guide action.

Look for

The two ends of the stretch: where you are now and where you want to be. The useful work begins by keeping both visible.

A vertical rubber band stretched between vision and reality, showing creative tension and emotional tension.

Creative tension holds vision and reality together. Emotional tension is the discomfort we feel inside that gap.

Listen for

The difference between using the gap to learn and quietly lowering the goal so the discomfort goes away.

Peter Senge on the gap. The man who wrote the book explains it in three minutes, in his own voice.

Open on YouTube ↗

So here is the idea.

Creative tension is the pull between two honest statements: what is true now, and what you want to create.

The same gap can also create emotional tension: frustration, anxiety, defensiveness, or impatience because current reality is not yet where you want it to be.

There are two common ways to resolve the tension. One is creative: keep the vision steady, face current reality clearly, and learn or act so reality moves closer to the vision. The other is relief-seeking: lower the vision, soften the facts, distract yourself, or explain the gap away so the discomfort fades.

The practice is to notice the emotional pull without letting it quietly shrink the goal. Hold both sides clearly: current reality and desired future.

Source note. Creative tension is associated with Peter Senge's work on personal mastery in The Fifth Discipline: the useful stretch between vision and current reality.

Before you move on

Where have you, or your team, quietly lowered a goal to make the discomfort go away?

Tool: Core Theory of Success

Core Theory of Success

Results improve through a loop: relationships shape thinking, thinking shapes action, action shapes results, and results shape relationships.

Look for

The loop, not the individual parts. Ask what changes when relationships improve the quality of thinking in the room.

A team improves or declines through the loop it keeps repeating.

Relationshipstrust and safety Thinkingbetter shared sense Actioncoordinated moves Resultsoutcomes feed back

So here is the idea.

Core Theory of Success is used here as a practical loop for team learning. It brings together a systems view of performance with research on teams: results are not produced by action alone. The quality of relationships affects the quality of thinking; the quality of thinking affects the quality of action; action affects results; and results feed back into relationships.

The first link matters because relationships shape what information enters the room. Amy Edmondson's research on psychological safety, and Google's study of more than 180 teams, both point to the same practical idea: when people feel safe to speak up, admit mistakes, and ask questions, the team gets better information to think with.

The loop can also run downwards. If people learn that speaking up is risky, they hold back. Thinking narrows, action weakens, results suffer, and trust drops further.

Watch for

Why speaking up is not only about being nice. It changes what information the team has available to think with.

Amy Edmondson — psychological safety. A useful companion idea: people contribute more of what they notice when the environment makes speaking up possible.

Source note. This loop is a learning synthesis, not a claim of original ownership. It is anchored in systems leadership and team learning practice, and strengthened here with Amy Edmondson's psychological-safety research and Google's Project Aristotle findings.

Tool: Advocacy and Inquiry

Advocacy and Inquiry

Make your own thinking visible, and invite others to make theirs visible too.

Watch for

How disagreement can become useful when it tests thinking, rather than simply trying to win a point.

Margaret Heffernan — dare to disagree. The useful version of disagreement is not argument for its own sake. It is a way to test what one person cannot see alone.

Open on TED ↗

Advocacy

State your view and show how you got there.

"Here is what I am seeing, and here is the assumption I am making."

Inquiry

Ask a real question to understand or test thinking.

"What led you to read it that way?"

1

Here is what I am seeing, and here is how I am interpreting it. What might I be missing?

2

What are you seeing that leads you to a different view?

So here is the idea.

Advocacy is not just pushing a position. Done well, it means sharing your view, the data you are using, and the assumptions behind it. You let others see your ladder, not just your conclusion.

Inquiry is not a question with an answer already hidden inside it. Done well, it draws out the other person's data, meanings, and assumptions. It helps you understand their ladder and check your own.

The balance matters. Too much advocacy can become persuasion. Too much inquiry can become vague or passive. Together, they make disagreement useful.

Source note. Advocacy and inquiry are common in organisational learning and action-science practice, especially the work of Chris Argyris and Donald Schön on making reasoning visible and testable.

Before you move on

In your last disagreement, were you mostly advocating, mostly inquiring, or balancing both?

Five of six

Tool: Mental Model

Mental Model

Every person makes sense of the system through prior experience, habits, and beliefs.

Try it as you watch

Play along with the number rule. Notice whether you test your first idea, or mostly look for evidence that confirms it.

Veritasium — the most common mistake your mind makes. A simple guessing game shows how people search for evidence that fits the answer already in mind.

Open on YouTube ↗

So here is the idea.

A mental model is the picture in your head of how something works. You may not have chosen it deliberately, but it still shapes what you notice, what you ignore, and what you do next.

In work settings, a mental model might sound like: "this unit prefers detail", "that stakeholder moves carefully", or "this issue is mainly a resourcing problem". Any of these may be partly true. The question is whether they have been checked recently.

They are also one of the deepest levels in Levels Perspective. If a belief keeps shaping the same pattern, changing the surface action may not be enough.

Source note. Mental models are one of Peter Senge's five learning disciplines in The Fifth Discipline, and are also central to systems thinking because assumptions often sit beneath recurring patterns.

Tool: Ladder of Inference

Ladder of Inference

Use this final tool to slow down the jump from what happened to what you decide to do.

Watch for

How quickly the mind moves from what it notices, to what it assumes, to what it does. The class terms below simplify the labels from the video.

TED-Ed — Rethinking Thinking. The lesson introduces the Ladder of Inference as a process for rethinking how we interpret interactions.

Open the TED-Ed lesson ↗
Actions. What we do, say, avoid, or decide.
Beliefs. What this seems to confirm about people, work, or the situation.
Conclusions. The judgement we arrive at.
Assumptions. The story we add to connect the dots.
Select Data. The slice of available data we notice and use.
Pool of Available Data.Everything that could be observed, asked, checked, or learned.

Reflexive loop

Our beliefs affect which data we select next time.

In the TED video, these ideas are described as raw data and observations, filtered information, assigned meaning, assumptions, conclusions, beliefs, and actions. In class, we will use the simpler labels shown here.

So here is the idea.

The ladder describes how quickly we move from data to action. We do not take in everything. We select some data, add assumptions, reach conclusions, reinforce beliefs, and then act as if our view is the whole picture.

This is useful because it separates what happened from the meaning we made from what happened. The meaning may be reasonable, but it is still worth checking before we act strongly.

There are two directions to remember. In real life, we usually climb up the ladder in seconds. In reflection, we deliberately walk down from our action to the data we selected. Then we expand the pool of available data and choose a more grounded next action.

Source note. The Ladder of Inference was first proposed by Chris Argyris and later popularised in organisational learning work, including The Fifth Discipline Fieldbook. The TED-Ed video uses more detailed labels; this page uses the class terms you will practise with.

Review the TED-Ed lesson ↗

What happens automatically

We climb up.

Something happens. We notice part of it, fill in a story, draw a conclusion, update a belief, and act. This is fast and often outside awareness.

What the tool helps us do

We walk down.

Start from your action or reaction, then trace the thinking back down: belief, conclusion, assumption, selected data, and the wider data pool.

What comes next

We widen the data.

Ask what else may be true, what data is missing, who else may see it differently, and what action would still help if your first assumption is only partly true.

Video example

The parking lot ladder, using class terms

The first pass shows the fast climb. The driver takes the lot, we select a few details, add a story, and move toward confrontation.

  1. 1Pool of Available DataA car moves into the parking spot. Your signal was on. You brake. The driver looks away. Other data is not yet known, including why the driver is rushing.
  2. 2Select DataYou focus on being cut off, the brake, your tightening grip, and the driver looking away.
  3. 3AssumptionsYou assume the driver saw your signal, ignored it, and decided their need mattered more than yours.
  4. 4ConclusionsYou conclude the driver is inconsiderate and should be challenged.
  5. 5BeliefsThis reinforces a belief that if you do not stand up immediately, people will take advantage.
  6. 6ActionsYou move behind the car, honk, and prepare to confront the driver.

Then new data enters the pool: the driver's wife is in labor. That does not mean the first reaction was foolish. It shows why the ladder is useful. When the data pool widens, the assumption changes, the conclusion changes, and a different action becomes possible.

Questions that help you change the action:

  • What did I actually observe, and what did I add?
  • What data did I select because it matched my belief?
  • What else could explain this situation?
  • What data would I need before acting strongly?
  • What action would still be useful if my assumption is only partly true?
Review the TED-Ed page ↗

Before you move on

Think of one work moment where you moved quickly from what happened to what you did. What data did you select, and what data might still be outside your view?

That is the six tools.

You have the preview for the upcoming class.

To improve a system, we often need to look at process, structure, incentives, and relationships. We also need to examine the thinking we bring into the system. That is why the final activity starts with one real moment you can look at with more curiosity.

Your task

Bring one real moment to class.

Choose a recent moment of tension, frustration, confusion, or strong reaction. You do not need to analyse it with the ladder yet. Describe what happened from your perspective, then turn it into a poster you can bring into class.

Choose a moment that feels safe enough
  1. It can be small: a message, a meeting comment, a decision, a silence, a queue, or a home moment.
  2. Choose something you are comfortable bringing into class. You can anonymise names, teams, and details.
  3. No need to solve it or decide who was right. For now, capture the scene clearly enough that another person can understand your perspective.
Progress saves on this device as you go.

Your moment

Tell the story from your perspective.

Describe one recent moment of tension, frustration, confusion, or strong reaction. What happened? Who was involved? What did you notice? What did you feel or think? What did you do next? What do you still wonder about?

You are bringing a moment, not a perfect analysis. The poster makes the moment concrete and a little more playful, so we have something useful to work with together.

Class poster
