Large Scale Design Method (LSDM)

Large products rarely fail because of bad screens. They fail because nobody agreed on the system underneath them.

LSDM is how I keep that system explicit: define the modules first, make each one functional on its own, and only then make them beautiful together.

In practice it means three passes over every feature — structure, behaviour, surface — and a rule that no pass borrows from the next one.

The method is not clever. It is just harder to skip.
