A general open source platform for effective management of organizations of all sizes. Continuously balance and optimize resources through a dedicated integrated application software package, thereby improving the efficiency of the implementation of the organization strategy of the enterprise or organization for the integration of production and operation, human resource management, financial management and asset management. The software package is for all activity fields Provide common data and process models. It can be used as an off-the-shelf application solution and includes other modules that work within the organizational structure of the enterprise (for example, for management purposes). The modular principle allows you to add required functions by selecting and configuring subsystems composed of standard modules. The final set of subsystems and module structures can be selected separately for the functions of the infrastructure of each enterprise (organization). The future of Russian business, its success and prospects are inseparable from the automation of business processes: today, this is no longer a question. The use of business process management system has a decisive impact on the company's competitiveness, enabling it to quickly adapt to changes in the surrounding business environment.
A convenient and practical tool for establishing and modeling business processes of enterprises of any size. Perform configuration and execution of various complex processes, monitor them, and form a single information space based on the system for enterprise employee interaction. In order to perform the most efficient work in monitoring, collecting, unifying, controlling and coordinating all data in the system, please use workflow technology to design business processes. The designer allows you to design regulated processes through an intuitive interface without the need for programmer involvement. Using technology when setting up the process allows you to minimize the customer's dependence on solution developers and significantly reduce the cost of improving the system in the future.
They can be connected to each other, and each can be seen as a separate object with input, output, curator and performer. The creation of business processes allows you to organize the operations of the system and control the quality of any operations performed in the system by analyzing the results obtained, the actors involved and the resources spent. The analysis results are presented to the manager in the form of reports.
The mechanism of the business process makes it possible not only to automate the sequential work chain, but also to perform conditional routing according to the described route map, and control the selection of pre-planned routes. Easy to use, simple tools can control the execution of assigned tasks and the overall progress of the process. For example, a tool that displays the movement of objects according to the configured business process and the corresponding notes of the responsible person. This tool provides the function of monitoring the running process, and you can also keep statistics of all running, completed and interrupted processes. Adjust the system setting parameters according to the changes in the organization's business process.
The system effectively solves the tasks of government agencies and large enterprises to standardize process automation through complex information flow solutions, while ensuring high performance, compatibility and data protection. It can be used in conjunction with other systems that perform its tasks in the company, or it can be produced independently of them. The system-oriented function provides the ability to access the server from any computer or mobile device of the user, so that you can quickly organize the remote work of your employees. In this way, you can solve problems related to introducing new features or revising existing features in the shortest time. It allows you to use built-in tools to reduce the time required to develop various forms of reports. This tool is a visual designer that allows you to select data sources and create report tables based on pre-prepared templates. It is a set of embedded special functions that can be used through settings without programming, which can greatly reduce the implementation time. This approach can greatly reduce the need for platform modifications, while providing maximum functionality for each customer. The new version expands the list of widgets supported in the dashboard.

This application allows you to create, edit and publish reports and dashboards easily and quickly. The application program interface provides a set of common tools located in the workspace. You can view the ready-made report in the "Viewer", which displays the images and documents (,, and other formats) added to the report. Viewer is not only a program to open files, but also a set of convenient tools for viewing, printing and exporting reports with all resources.
For many people, drafting reports seems boring and routine. Usually, the reason for this attitude is that the usual reports are a large number of tables and texts of the same type, and it is not a creative job to lay them out into a single document. In addition, viewing such standard reports is not a good thing. It fundamentally changes the way of reporting, making it enjoyable and the most important thing is easy. This is possible due to the various tools used in the program, and these tools allow a high level of visibility in the document. Interactive diagrams, selection of fonts and design styles, illustrations, links and other components, as well as the possibility of customizable creation and presentation of documents that can be conveniently and interestingly interacted with experts from different departments of organizations in any outline and field To interact. The system supports the possibility of retrospective evaluation and predictive analysis of various indicators, which enables managers to make strategic decisions and predict organizational performance indicators. This module is based on mathematical models constructed using artificial neural networks, technology, fuzzy logic methods and machine inference. This allows you to automate any process: organization, technology, regulations, management. In particular, automated data loading (*, *., *. files; databases, multidimensional cubes, data models,,) and quality control of financial and reporting documents. The analysis and report data can be accessed from any device and operating system of the user. Used by banks, telecommunications and logistics operators, retailers, government agencies, etc. These technologies have many applications. In this article, we will introduce in more detail how to use to handle citizen requests, because this task is related to many companies.
The platform has been selected as two key development areas. First, this is the transition from the platform and all modular components to the updated 3.1 framework. Secondly, by improving the system's built-in modules to increase the flexibility of platform settings, so that the software solution can be adapted to the emerging task categories to be solved without changing the source code.
Allows to significantly improve performance and stability under high loads, including increasing the speed of release updates. The updated version of the platform also provides good cross-platform features and can be used in it, thereby providing the possibility of fault-tolerant operation, load balancing, and vertical and horizontal scaling functions. Since most of the services of the platform are collected in high-performance and fault-tolerant software clusters, which can be used in high-load information systems, the high efficiency of horizontal scalability can be achieved.
The constructors of dictionaries and classifiers allow you to add object types and types.
The update also affected the designer of the analysis report. Allows you to use built-in tools to reduce the time to develop various forms of reports, and also provides users with an editor for tables and text files.

Allows you to add the required functions by selecting and configuring a subsystem composed of standard modules. The final set of subsystems and module structures can be selected separately for the functions of the infrastructure of each enterprise (organization).
Subsystems are made in the following areas of the enterprise (organization):.
The figure below shows that it is designed for large enterprises in the public and corporate sectors.
In the form of a link diagram, available here.
The functions and processes that automate the simplest process of an enterprise or organization are combined into modules. These modules are combined into subsystems, which can automatically complete the complex tasks assigned to the various structural departments of the enterprise. In turn, the subsystems are functionally combined according to the activity areas of enterprise automation. At the same time, in order to minimize the resources used, place the same functions in common modules and subsystems. The financial management subsystem ensures the formation and control of the execution of the enterprise (organization) budget: funding and development of received (allocated) financial resources.
By interacting with a single integrated bus subsystem, data can be received from external financial and accounting systems. The function of organizing projects in a hierarchical structure is realized.
