Don’t expect to get it right the first time. Let the app grow and speak to you. Let it morph and evolve. With web-based software there’s no need to ship perfection. Design screens, use them, analyze them, and then start over again.
You don’t need to aim for perfection on the first try if you know it’s just going to be done again later anyway. Knowing that you’re going to revisit issues is a great motivator to just get ideas out there to see if they’ll fly.
