Business planning for success—reducing assumptions
Note: this post was written a few weeks ago, I just forgot to publish it.
Credit crisis, schmedit smeisis, I decided to just not care about it. Life is hard, it may have become harder, but that doesn’t meant that we shouldn’t just get on with it (a little harder) too. One of the issues today is whether it’s a good time to start a business and/or be in the early stages of a business. Because you’re in the money-begging phase and it seems like that’s in short supply right about now. I also decided to not care about that either. “Begging” for money is a psychological game: you present arguments and based on those you either get money or you don’t. If you don’t, you improve your arguments.
One tool to do that is to reduce assumptions to the absolute minimum. An article from my studies that always stayed with me, is entitled “Critical assumption planning – a practical tool for managing business development risk” and the diagram below is taken from it.

What is the point? An assumption is a guess that you make about a topic. I assume that (so many) people will buy my product, or I assume that building this machine for my company will take so many years, or I assume that my medical product will be approved by the relevant regulatory parties. Etc. etc. Each of these guesses, if wrong, can be fatal to your project, you know that and your investors know that. So how do you turn guesses into “truth,” or rather, into a perceived* truth (*: the fact is that nothing can be predicted 100%)?
Somewhat simple: triangulation. Triangulation means that you don’t trust single sources, least of all yourself, but rather place your faith in the power of many. To give you an example, for my current (non-tech) venture, I’ve divided our assumptions into 5 parts:
- Who our consumer is
- What the size of our market is
- Who our competitors are
- What our value proposition should be
- And how this should work financially
Each of these are important things to work out and represent different challenges in doing so.
For our customers, I could send out a survey, but how can I be certain that the questions are the right ones and that it reaches the right audience? Instead, I chose for surveys and face-to-face interviews, and, guess what, some of my survey-questions were phrased* wrongly (*: the biggest danger in designing surveys). For our market, I have import-data for our industry from the government, which is itself based on estimates and doesn’t take into account different classes of products. So I have to sanity-check those figures with experts in that industry. And so on…
In the end, you should have the ingredients for a picture of your business-proposition, one you can work out into a number of pages or slides and present to potential investors and partners. And one that can act as the blueprint for what your business should look like. And if someone questions your assumptions, you can tick off, point by point, each of the reasons why you think you are right. That should be a nice feeling!
Does this method of planning apply to all types of ventures? It could be argued that it’s most relevant to projects where the price of failure is expensive, e.g. real-estate. Starting something online may be much cheaper and quicker (perhaps), but I wouldn’t say that the price of failure is cheap. If you want to start something that you want to live off, that your co-founders and employees want to live off, then I’d say that the price of failure is pretty expensive for you and them too, and that having done your homework beforehand is a good thing!
Feedback on my own assumptions in this post are, as always, welcome!
