The customer decides, based on values determined by estimation, whether to realize SW project and whether to realize the project in given range; i.e. the customer is interested in the project not being overestimated. The supplier of IT services plans project elaborateness according to availability of their capacity, i.e. there is the interest of the supplier in project not being underestimated. The text addresses the topic of designing a method for creating estimation of SW project range by means of expert estimation modification with consideration of historical data.
