If your system contains 2 main modules (Web App + Back-End) and a
                                    small number of features - this is a
                                    system
                                    Low Complexity. 
                                    For example, it could be a system for rating
                                    employees or a system for sending corporate notifications, chat bots or simple data
                                    analysis processor. 
                                    If your system has a mobile application as well or a reporting system, then your
                                    system goes to the Middle Level.
                                
                                
                                    If your system contains such functionality as reporting, payments, access rights
                                    management, multi-level user roles, several integrations with third-party products,
                                    and more, then your system is of
                                    Mid Complexity. 
                                    For example, it could be a video conferencing application or an order processing
                                    system, a data visualization system, or a small aggregator. 
                                    If your system has video conferencing, online calls, time tracking, real-time data
                                    or analytics and statistics, then your system belongs to systems of High
                                        Complexity .
                                
                                
                                    Analytics, statistics, work with data visualization, many integrations with
                                    third-party software, real-time data, big data and everything related to these
                                    sections in one way or another indicates that your system is a system of
                                    High Complexity. 
                                    For example, such systems can be AdTech Networks, Game Engines, full-fledged
                                    enterprise management systems, reporting systems, any product with 3D graphics,
                                    logistics and delivery systems, etc.
