Tazama is a rules-based system explainable to regulators and all those involved in a transaction. If a transaction is blocked you will know which rule is broken and why, which grouping of rules created the pattern that breaks the typology and why, and all of this is done in real time and fast enough to not bother your end user.

That explainability is important to you and the regulator. You need to know why you stopped a transaction and be able to explain it to the regulator when you report it. It also lets you get started right away. There is no need for training, which is required in many ai systems. The explainability will keep the regulators happy. Calibrate the system as you go.
