Why is that? The intent was there; the energy was present; and ideas were flowing. That's the easy part _ coming up with the ideas. The success of your planning doesn't rest on the ideas, but rather, implementing those ideas. It's true, companies need to foster innovation in their business planning, but more importantly, they need to create a business environment that enables team members to execute these ideas with an "on_time, on_budget" mindset. That is where the work begins.
It could be, for example, the risk of a change in the economic environment _ what are your contingency plans for that in terms of dealing with such a situation? There may be many other risks as well specific to your particular sphere of operation, but that ability to plan ahead for all scenarios makes for a robust business plan. When I have received business plans, the very best responses come from people who have looked at the risks and have an answer for every question. What you never want is to throw a scenario at your plan and have to answer "I don't know what I would do in that situation". You want to plan for every possible contingency, and certainly all the major risks to the ongoing success of your business.
