In my recent experience with startups, or at the very least ideas for startups, I'm beginning to find that not acting upon your ideas quickly can also be detrimental to your startup. Being stuck in the "Product Development Diagram," particularly in the "Concept/Bus. Plan" phase can allow others with similar ideas to get a head start, and possibly even get to launch before you've even started. Personally, I think that by getting into the development of your idea as soon as possible will help you. As an added bonus, there are always ideas, features, or a different method of implementation that get brought up while you are developing that you cannot anticipate during the planning/conceptualizing phase.
