One model is misdiagnosis. Ten is understanding. A hundred is judgment.
New · Diagnostic
Nine questions. You'll learn which three models you already lean on, how you approach problems, and how to use them to design the right incentives.
The catalog below is the library. These four lessons teach how a senior operator actually wields a model in a live room. Hover any underlined term to see the definition.
Skinner is running your weekly leadership meeting whether you know it or not. The behaviors that get praised, the misses that get punished, and the moments that get ignored together form an operant schedule that conditions your senior team week after week.
A conscious leader designs that schedule deliberately. An unconscious one inherits it.
A predictable bonus loses its motivational pull within one cycle. A variable, well-timed reward — recognition that arrives at the moment of positive surprise — keeps shaping behavior for years. This is why spot bonuses outperform scheduled ones at a fraction of the cost.
The lesson is not "pay less." It is "pay better, less often, and never on a calendar."
The principal-agent problem is not just for asset managers. It shows up between CEO and board, between executive and team, between team and individual contributor. The agent's incentives are never identical to the principal's. The question is how aligned, and how visibly.
Most "execution problems" are agency problems wearing different clothes.
First-order thinking asks "what will happen?" Second-order thinking asks "and then what?" Almost every comp plan, KPI, and policy fails on second order. The discipline is to write the second-order paragraph before approving the first-order change.

Vision is leverage. Vision unmoored from physics is fraud waiting to be discovered.
Pair every reality-distortion claim with falsifiable milestones and external audit.
Some tensions aren't problems to solve — they're polarities to manage (centralize vs decentralize, structure vs freedom).
"Treat a polarity as a problem and you'll oscillate forever."
Open full entry →Barry Johnson's Polarity Management — both poles have upsides and downsides; the goal is the figure-8 between them.
Most reorgs are a polarity being mistaken for a problem.
Before solving, ask: 'Is this a problem (one right answer) or a polarity (both sides needed forever)?'
Basics first (health/finances), then depth (mastery/impact), then altruism (widening circle).
"Skip the basics and the rest collapses. Skip altruism and the depth feels hollow."

"Most decisions are downloads of the past. Theory U asks you to stop downloading."
Open full entry →MIT Presencing Institute case work across school systems, hospitals, and the UN Global Compact.
When the same strategy keeps producing the same disappointing results, you're stuck at the top of the U.

"If you already know what they're going to say, you're at level one."
Open full entry →Scharmer's diagnostic for executive teams stuck in groupthink.
Why town halls feel hollow — the room never gets past confirming what everyone already believed.
Name the level you're at. Push one level deeper before responding.
Sort situations into Clear, Complicated, Complex, Chaotic, or Confused — each needs a different response.
"Best-practice answers in complex domains aren't best. They're hazardous."
Open full entry →Dave Snowden's sense-making framework, widely adopted in defense, healthcare, and software.
Treating a complex problem as merely complicated is the most common strategic error.

Open full entry →Used across systems thinking, public health, and climate policy.
Quarterly reviews almost always operate at the event layer. Strategy lives below.
For any recurring problem, ask: what patterns? what structures? what beliefs? Intervene at the deepest layer you can reach.

"By the time you're certain, you've climbed seven rungs and forgotten the data at the bottom."
Open full entry →Chris Argyris's framework popularized in Peter Senge's 'The Fifth Discipline.'
Most cross-functional fights are two people standing on rung 6 of different ladders, arguing about what's true.
Walk back down: what data did I select? what meaning did I add? what would change my conclusion?
Single-loop fixes the action. Double-loop questions the goal or model that produced it.
"Trying harder is single-loop. Asking 'are we even solving the right problem?' is double-loop."
Open full entry →Argyris & Schön's research on defensive routines inside organizations.
Most retrospectives are single-loop in disguise — they tune the recipe instead of questioning the cookbook.
After every post-mortem, force one double-loop question before closing out.
Behaviors you can't change are usually protecting a hidden, competing commitment.
"You're not weak-willed. You're doing exactly what your bigger commitment requires."
Open full entry →Kegan & Lahey's diagnostic from 'Immunity to Change' (Harvard).
Why training programs about behavior change rarely change behavior.

"Most strategy is verbal. Wardley turns it into a map you can be wrong about."
Open full entry →Simon Wardley's mapping work at Canonical and across UK government digital service.

"Most 'root cause' analysis stops one arrow too early."
Open full entry →Standard tool in system dynamics, from Forrester to Sterman.
Why every push for short-term metrics eventually produces a balancing loop that erodes the metric.
Draw the loops before drawing the action plan. Look for delays — they're where surprises live.

"Painkillers don't heal the injury. They make the injury easier to ignore."
Open full entry →Senge's archetype: relying on external consultants weakens internal capability over time.
Why short-term incentives often quietly destroy long-term competence.
Whenever you reach for a symptomatic fix, plan the fundamental fix in the same meeting.
