We have considered the conditions for developing engineering services for small and medium-sized businesses engaged in manufacturing. We have established that engineering, which is a costly and fairly risky activity aimed at rapidly implementing technological solutions, is an important direction for development. We have systematized the specifics of development of engineering services in the Pskov Region. We have considered in detail the conditions for development of engineering services in the Pskov region in three main groups: regulatory and legal, production capacity and support infrastructure. The engineering aspects of the system of strategic and result-oriented planning documents are presented. Potential consumers of engineering services in the Pskov Region are divided into three groups: the industrial electrical cluster; Moglino, a special economic zone of industrial production type; industrial enterprises of the Pskov region. We have assessed specific engineering tasks that small and medium-sized manufacturing enterprises are incapable of solving independently. The article proposes the segmentation of consumers of engineering services among small and medium-sized businesses engaged in a particular type of production activity, ranking the subjects according to a number of economic criteria or their combination: key economic indicators of performance (the amount of revenue, investment and fixed assets per production enterprise); the structure of certain types of costs for production and sale of goods; the growth rate (reduction) of costs of machinery, equipment and vehicles; the degree of wear and tear of machinery and vehicles; the dynamics of the degree of influence of innovation results on compliance with modern technical regulations, rules and standards. We have considered the structure of regional infrastructure support of engineering services, including financial, information and consulting and property support, support of export and investment activities. We have assessed the production potential, described the infrastructure of development of small and medium-sized businesses of the region from the standpoint of segmentation of consumers of engineering services. As a conclusion, we have highlighted the most obvious conditions for developing engineering services for small and medium-sized businesses in the Pskov Region.
