METHOD OF VERBAL ANALYSIS OF SOLUTIONS FOR THE SOFTWARE SELECTION FOR CUSTOMER RELATIONSHIP MANAGEMENT
E.S. Egorova, N.A. Popova
The relevance of the article is due to the existing difficulty in making decisions in the process of choosing software products that automate business processes of enterprises, including customer relationship management. Therefore, for a diverse analysis of systems, it is proposed to use a two-stage methodology for a formalized assessment of the functionality of software and systems. At the first stage, the results of a multivariate analysis of customer relationship management software are presented. During the criteria-based assessment, the functional and instrumental characteristics necessary for products of this type were selected. The results of the analysis showed that using this approach it is quite difficult to make a decision on the choice of a product, since all systems have approximately the same sets of functional capabilities. At the second stage of the study, in the process of determining the optimal system, it is proposed to use the method of verbal analysis of solutions to find the best alternative. As a result of a formal analysis of systems using the developed software application, a potential leader was identified among the systems under consideration, however, further research involving an expert and comparing all pairs of systems according to their strengths and weaknesses made it possible to distinguish another alternative among customer relationship management systems. The method of verbal decision analysis based on the opinion of experts in the field of design allows you to choose the most effective tool in a specific industry area, and the developed software application allows you to optimize the work of analysts.
Keywords: verbal decision analysis method, software, customer relationship management, CRM system, formal analysis of a set of initial alternatives, scale of normalized ordered differences.
THE CALCULATE OF THE TIME COUNT SPENT ON A SELECTING OF SOFTWARE APPLICATION GUI ELEMENT
A.R. Familnov, V.S. Zarubin, A.N. Morozov
The article deals with the quality assessment of user interfaces (UI) of computer programs based on the proposed mathematical model. Most often, the quality indicator of a UI is understood as the total time of elementary operations (actions) of users on UI elements (UIE) spent on solving a specific task. UIE means such interface elements as input fields, icons, various types of lists, tables, etc. The elementary actions are understood as finding, achieving and managing UIE. Сalculating the time to perform user actions can be quite complicated. This is due to the fact that for the calculation it is necessary to know which screen form and which computer program the UIE belongs to, and also in the solution of which problem it participates and in what sequence. The article proposes a conceptual model of IDUs based on the ER diagram, which includes entities describing the UIs and the relationships between them. Analytical dependences are obtained for the calculation of one of the components of the quality index of computer programs, namely, the time the user spent finding interface elements placed on the monitor. It is shown that the entities included in the ER-diagram are indexed sequences. To navigate in the ER-diagram, functions are proposed that allow you to find an element of a set by its index in the task profile, and vice versa – to find the index of a given element of the set. The calculation of the time spent by the user in finding the interface elements on the monitor is performed using Hick’s law.

THE USE OF MULTIVARIATE ANALYSIS TO ASSESS THE FUNCTIONALITY OF THE PROJECT MANAGEMENT SYSTEMS
E.S. Egorova, N.A. Popova
The relevance of the article is due to the existing complexity in the selection of software products that can effectively manage projects in various fields of activity. Therefore, for a full-fledged, diverse analysis of the systems represented on the industry market, it has been proposed to use a two-step method of formalized evaluation of the functionality of software and systems. As a result of the first stage, the results of a multivariate analysis of the software of automated project management systems currently on the market are presented. In the course of the criterion assessment, the functional and instrumental characteristics required for products of this type were selected. For each indicator, it has been proposed to use weights and ranking maps. The results of the analysis showed that the most important indicators for evaluating the automated project management software are: integration mechanisms with third-party systems, the possibility of networked multi-user interaction, technology for organizing business management processes in project management systems. At the second stage of the research, it was proposed, using functional and instrumental characteristics, to rank software products based on the opinion of experts in the field of design. For this, the method of verbal analysis of decisions was used. Thus, the evaluation of software products has allowed to conclude that in the market there are universal software that has its own advantages and disadvantages, but is not suitable for use in highly specialized areas. However, the method of verbal analysis of decisions based on the opinions of experts in the field of design allows you to choose the most effective tool for project management in a specific industry area.
