Causality in Modeling
Any business system is a set of reactions to events. When designing a product, it is important to clearly understand: which user action is the cause, and which system event is the consequence.
Typical Modeling Mistakes
- Ignoring intermediate system states.
- Violating the logical sequence of transactions.
- Mixing business logic and views (UI).
A proper model must be predictable and transparent, where every change in the system state has a clearly justified reason.
