What each ingredient does

Butter
Melts to form the body and rich flavour of the sauce.
Flour
Thickens the melted butter into a smooth, cohesive sauce.
Water
Adds moisture so the butter and flour blend into a pourable sauce.

The step that matters

Shaking the saucepan constantly while it melts. Constant shaking keeps the butter and flour moving so they emulsify evenly and do not scorch or separate on the hot bottom of the pan. Stirring or shaking in a water bath also heats the mixture gently, which helps prevent the sauce from breaking.
