ERP SYSTEMS IMPLEMENTATION EFFICIENCY MODELING IN SMALL AND MEDIUM SIZE ENTERPRISES (SMEs)

An original method of ERP in SME implementation efficiency assessment (EWE) is developed. It consists of 5 elements, that is: (1) ERP system parameters, (2) SME company parameters, (3) an SME experience which proceeded the ERP project, (4) functionality indicators values, (5) an algorithm that enables ERP and SME characteristics binding – a GMDH algorithm. The application of this method allows predicting economical effects as far as the implementation of ERP is concerned, taking into consideration efficiency indicators in the analyzed company. On the basis of the EWE method, a decision model for ERP efficiency implementation has been developed.
