+## Label Description
+### Priority Score
+* **Low** label, means that the temporary/corrective solution can solve the problem. A permanent solution will be provided later because the impact on the business can still be handled.
+* **Medium** label, means that there's a need to determine the time constraint to solve the problem. If it remains too long, it will impact the business side.
+* **High** label, means that the problem is urgent and must be solved immediately.
+### Problem Domain
+* **Operational** label, means that the scope of the problem is on the business or daily operational.
+* **Technical** label, means that the scope of the problem is on the technical (technology) side like the mobile/web application.
