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.
