Whether you use a purchased model or build one yourself, IMHO having a good model that allows you to run scenarios to predict potential futures for your company is absolutely essential. I live in my model every day, running scenarios to test out ideas for financing and to gauge downside risks. Without a decent model, I would be absolutely lost.
