Better systems start with better thinking.

Often described as Kidlin's Law

Problem Clarity

A clearly stated problem is already partly solved.

Writing a problem clearly forces assumptions, constraints, people, and outcomes into view before a solution takes over the conversation.

Gall's Law

Working complexity grows from working simplicity.

A reliable complex system is usually evolved from a simpler system that already worked—not designed as one giant finished system from day one.

The 80/20 rule

Pareto Principle

A small number of causes often create most of the outcome.

The useful lesson is not that every split is exactly 80/20. It is that effort and impact are often uneven—and prioritisation should reflect that.
