- 32. Four Myths Only experts create good designs Ä experts faster, simple and effective techniques anyone can apply We can fix the user interface at the end Ä good design is more than just user interface Ä having right features, building those features right Good design takes too long / costs too much Ä simple and effective techniques can reduce total development time & cost (finds problems early on) Good design is just cool graphics Ä graphics part of bigger picture of what to communicate & how
