This may be a bit off-topic for this group, but here goes anyway...
As I mentioned here before, I am in the process of starting a new business based around turning a hobby project of the last few years into a commercial venture. I'm going through the whole process of developing a business plan for three to five years with projections for sales, revenue, routes to market, staff levels, expenses, R&D investment, etc.
This is presented by advisors as a necessary step. How can you be confident the business will succeed, they ask, without a clear picture of the end goal and a good idea of how you are going to get there.
But, I respond (ignoring everything my English teacher tried to drill into me), I know the rough outline of what I want in three years, and I know that the major milestones on the way are A, B and C.
Yes, they retort, but you have no balance sheet for the end of year two, and no indication of how you will spend the marketing budget in years two or three.
And so it goes back and forth. I resist what amounts to BDUF in the business plan, while being pressed for more and more detailed projections.
So do any of you inventors of process care to take on the challenge of FDD for business planning? ;)
