Big problems dissolve when cut into elemental parts.

Learning goal

Break the problem into sub-problems or components.
Identify which parts can be tested or solved independently.
Choose the first slice to work on.

Why it matters

One big blob is paralyzing.
Small parts can be completed and tested.
Decomposition reveals leverage points.

Key idea

Decomposition is breaking a big problem into smaller, elemental parts. Big problems dissolve when cut into parts. Then pick the first slice or the leverage point.

Procedure

List sub-problems or components.
For each: can it be solved or tested independently?
Identify which component, if fixed, would ease the rest (leverage point).
Pick the first move on the leverage point or the smallest testable slice.

Common mistakes

Trying to solve the whole thing at once.
Decomposing into too many tiny pieces with no prioritization.
Ignoring dependencies between parts.

Today's move

Decompose your working problem into 3–5 sub-parts. Mark which one is the leverage point or the smallest testable slice. Choose the first move on that.
