A cost model is an approach to estimate the efforts and expenses necessary in order to achieve a business goal, e.g. to produce a good or a service. Taking into account respective requirements and available resources, costs can be appraised in a top down way (i.e. giving a limit by estimating the acceptable costs of the overall product first) or in a bottom up way (i.e. estimating and adding up costs for each individual subpart or function). A cost model can be based on experiences (i.e. a knowledge base) or can be realized as a specific algorithm (i.e. a set of functions).
