What are non-functional requirements? MAU, seasonality, conversion, performance.

Non-functional requirements are system parameters not directly related to its functionality but critical for successful operation:

• MAU (Monthly Active Users) — the number of active users per month, affecting scalability and load.
• Seasonality — fluctuations in load depending on the time of year or events, requiring flexible resource management.
• Conversion — the effectiveness of user transitions through the funnel, important for business analytics.
• Performance — response speed and data processing, impacting user experience.

When designing a system in Python, it is important to consider these parameters for architecture selection, code optimization, and infrastructure planning.
