Currently, the increase in financial returns from economic operations is constrained in view of the lack of a single efficiency criterion, which allows uniquely identify the business operation by their main feature - the possibility of obtaining the maximum value added (profit). One of the main scientific steps on the way to obtaining the formula of efficiency is developing the "resource intensity" indicator. The development of this indicator was based on the model of the deployed operation and determination of the time of the actual completion of the target operation, which does not coincide with the traditional notion of the time of completion of economic operations. For processes with distributed parameters, an expression for determining the resource intensity using numerical methods was derived. For economic operations, which can be reduced to simple operations, an analytical expression of resource intensity was obtained. Using mathematical modeling methods it was revealed that in the case of a fixed value of expert (cost) estimate of output products of the operation, the minimum resource intensity of the operation indicates a maximum efficiency operation with respect to the target product of the operation. Development of the resource intensity of economic operations is the final step towards the development of cybernetic (interdisciplinary) efficiency indicator that allows to maximize the value added (profit) of economic operations.
