Benefits of Event Sourcing

Event sourcing is an iterative and flexible design approach.

We need to ensure that our products are reliable. This is not the same as AB testing, which focuses on user behavior through an established UI. Instead, it pertains to how a business plans to provide value to its customers.

It is invaluable to trace back potential issues in time, whether three months ago or even years ago.

In that case, we need to have the ability to investigate and identify what caused this error. Event sourcing provides a mechanism to debug the timeline for the whole system.
