== Process of assumptionAssumption-basedBased planningPlanning (ABP)==
[[File:ABP process.gif|thumb|320px|Assumption-basedBased planningPlanning (ABP). The blue part of the figure depicts the process steps of a general assumption based planning method, the white part identifies the separate deliverables. Every step is described in the assumption based planning process list displayed below the picture.<ref>The modelling method in general is a result from a method engineering approach as proposed by the [[University of Utrecht]] in its "Method Engineering Encyclopedia"</ref>]]
The steps of assumptionAssumption-basedBased planningPlanning (ABP) are:
* Identify assumptions: Collect all assumptions implicit, explicit, primary and derivative, out of the (business) plan.
* Determine criticality: Try to quantify the assumptions as much as possible in order to determine which assumptions have the greatest (financial) impact.
