Conventional business planning methods operate on the premise that managers can extrapolate future results from a well-understood base of information from the past. However, for new businesses and projects this way of planning often does not comply. Most of the time there is no past-knowledge and if there’s any past knowledge available, predicting the future out of it is nearly impossible. The dilemma is that corporate planning techniques often presume more knowledge than exists, leading to grave errors in managing innovation projects <ref>Christensen, C., Kaufman, S., & Shih, W. 2008. Innovation killers: how financial tools destroy your capacity to do new things. Harvard Business Review, 86(1): 98-105, 137.</ref>.
 
The managers’ solution to this problem is to make assumptions; their best try to predict the future. Some of the assumptions made during the planning process are very likely to come true; the outcome of others is very much uncertain, though not less important. Assumption based planning is about the identification and testing of the assumptions made in a [[business plan]], the formulation of “hedging actions” and the construction of “what-if” scenario’s.
