The aim of the article. The purpose of the article is the development of a technique of choosing the most effective option of a technological business-process of an nstrument-making enterprise from alternative options of its implementation, obtained as a result of re-engineering.

The results of the analysis. This article summarizes the main approaches to the interpretation of the economic category ‘efficiency’. The classification of indicators of efficiency is characterized. The model of evaluating the comparative efficiency of the existing and the obtained business processes as a result of reengineering  of instrument-making enterprises based on comparative evaluation of Data Envelopment Analysis objects – DEA, which, unlike the existing ones, allows to calculate the relative efficiency of alternative business processes regardless of the dimension of input and output options of instrument-making enterprises business processes.

For the economic rationale of the implementation of reengineering of business processes in instrument-making enterprises the article deals with the redesigning of the business process of dosimeter assembly ‘TERRA’ using a systematic approach to the organization and improvement of method of work SREDIM, which allows a multiple description of it. As a result of redesigning, a number of technological operations of the process is reduced, some original parts are substituted for unified and standard ones, new technical solutions as to changes of the methods of adjusting device are suggested. The results of economic-mathematical modeling by using the proposed model reflect higher relative efficiency of business processes of dosimeter assembly ‘Terra’ after its re-engineering. The improved technique of evaluating the comparative efficiency of the existing business processes and the alternative ones, obtained as a result of re-engineering, draws attentionvof executives, managers and engineers draw attention to taking optimal decisions about choosing the most efficient of business processesor putting into practice at instrument-making enterprises by developing relevant projects in this area.

Conclusions and directions for further research. The developed technique of evaluating comparative efficiency of alternative options of technological business processes of instrument-making enterprises based on the method MOD allows to get a result quickly and relatively easy. Moreover, the obtained result takes into account both the economic and technical components of business process efficiency, which is the main advantage of this technique over the existing ones. However, the given technique does not take into consideration the risks that inevitably arise during the implementation of projects of business processes reengineering. Evaluation and minimization of these risks are the prospects of further research.
