The article analyzes the organization of information support of small business structures (SBS). The importance of information support in making management decisions is shown. The definition of the concept of information support and the definition of its requirements are given. It is proposed to present information support of small business structures in four interrelated levels: with dynamic information with high rate of change, which requires constant monitoring (information on the external environment and operational management) and quasi-static information (on the organization of internal activities). The main obstacles that complicate their information support are given. It is shown that a significant contribution to the creation of information support of SBS is the application of the concept of collective intelligence to identify both problem areas in the activities of SBS and to identify alternatives to support the search and management decisions. The proposed solutions were tested at one of the small enterprises in Odessa and showed positive results.

The object of research is the process of forming a collective expert assessment with increased reliability in making management decisions in business structures by an expanded team of experts. One of the most problematic places in the expert assessment of management decisions is the complexity of forming a competent expert team and the rather high cost of the expertise. In recent years, there has been a tendency for expert assessment with an expanded team of experts. In this case, not only professional experts are involved in the examination, but also all persons wishing to take part in solving the problem. In this case, the reliability of the examination raises doubts. In connection with the participation in expert assessment of persons who do not have experience in expert work, a wide range of expert assessments is possible. The analysis of the current state of the methods of expert assessment in business is carried out. It has been established that the Delphi method, which was most used until recently, does not meet modern requirements. More progressive methods are based on mathematical consensus theory. Consensus is understood as the degree of correlation of individual expert assessments performed in rank scales. In the course of the study, formalized mathematical approaches to the organization of collective expertise were used. A method for processing the results of an examination with an expanded composition of experts was developed. The developed methodology is focused on identifying experts with insufficient qualifications. The methodology allows for a step-by-step assessment of the reliability of the collective expert decision by assessing the Kendall concordance coefficient. It is shown that the phased exclusion of assessments by experts with insufficient qualifications allows increasing the level of consensus, the quality and reliability of the collective expert assessment. The developed methodology has been tested in a really functioning enterprise to make a decision on the exit strategy of the enterprise from their crisis. The use of the developed methodology has made it possible to significantly increase the reliability of the examination results, assessed by the concordance coefficient. The results are useful for practical application in business structures when conducting expert examinations involving a wide range of participants.

The article analyzes the features of management decision-making (DM) in small and medium-sized businesses in a dynamic change. It is shown that the importance of management decisions in recent decades has increased significantly. The peculiarities of managerial decisionmaking in SMB in the conditions of dynamic changes are analyzed.The influence of limitations is shown and the basic criteria of an estimation of administrative decisions are noted. It is noted that the most effective means of supporting management decisions are expert methods that have proven themselves both for assessing and forecasting the characteristics of the market object and for developing scenarios for enterprise development.It is shown that in the presence of a high organizational culture at the enterprise, it is advisable to conduct an examination by a team of insider experts. The principles of development and decision-making by a team of insider experts are given, which allow to significantly reduce costs. The expediency of conducting an expert evaluation by a team of insider experts is substantiated.

Information support of dynamic business process management with collective expert evaluation. The principles of information support of business process dynamic management by collective assessment by a team of insider experts in the conditions of dynamic changes and information uncertainty are developed. Information support of dynamic management is based on the formation of a team of expert insiders who are employees of the enterprise, who know and understand the problems of the enterprise from within and are interested in solving problems of the enterprise. The main stages of collective expert evaluation and its features in the implementation of the concept of "collective intelligence" are considered. The main advantages of collective expert evaluation with the involvement of insider experts are shown. Approbation of the proposed concept showed its effectiveness.
