After 100+ website design and development projects, I can tell you exactly why most of them take 4–6 months: It's not design. It's not the development. It's the 11 days between each round of feedback where nothing happens. We tracked this internally across multiple projects. On a typical project, the actual working time is about 4 weeks. The other 2 months? Waiting. For feedback, for assets, for someone to decide on a headline. So we built our entire delivery system around killing that dead time. We submit work daily. Clients respond within 12 hours. Next iteration ships next morning. That's how we go from kickoff to live site in 4–6 weeks.
