A curated set of frameworks for making decisions, solving problems, understanding systems, and communicating clearly — each explained with steps, a worked example, and pitfalls.
Move up for ‘why’ and down for ‘how’ to frame a problem at the right level.
The mechanism that resists change and pushes a system toward stability.
Diagram how ideas in a domain relate, with labelled links.
Let how sure you are decide whether to ship fast or build carefully.
Find the win-win hidden beneath a conflict’s surface trade-off.
Map how the elements of a system influence each other to find feedback loops.
Match your response to the kind of situation you are actually in.
Score options against weighted criteria to choose without gut-bias.
Sort tasks by importance and urgency so the important stops losing to the merely urgent.
Strip a problem to its fundamental truths and reason up from there.
Diagnose what kind of choice you face before agonising over it.
Look beneath events to patterns, structures and mental models.
Prioritise by plotting the payoff against the work required.
Solve the problem backwards — ask how to guarantee failure, then avoid it.
Map the many possible causes of a problem as a fishbone.
Break a big problem into a MECE tree of smaller, solvable parts.
Trace how you climbed from raw facts to a conclusion — and where you jumped.
Lead with the answer, then support it — structure that respects the reader’s time.
Observe, Orient, Decide, Act — and cycle faster than the situation changes.
A six-step path from messy problem to tested solution.
The engine behind exponential growth — and runaway collapse.
Ask ‘and then what?’ — trace the consequences of the consequences.
Give feedback that lands — describe the situation, the behaviour, and its impact.
Look at a decision from six deliberate perspectives, one at a time.
Combine the parameters of a problem to generate options you’d never brainstorm.
