Quality is a habit of noticing.

Producing good work is largely a matter of seeing what is wrong with it, and seeing is a habit rather than a talent. People who consistently notice the loose end, the slightly off word, the number that does not look right, have trained themselves to look rather than being naturally more perceptive. Noticing can be practised like anything else.

Build in a deliberate pass where your only job is to find problems, separate from the pass where you make things. Different mode, different attention. Most quality issues survive because nobody was specifically looking for them.
