Bug Severity Assignment

When bugs are filed we tag them with a “Severity” flag in the bug report. This severity flag has values from S1 to S4 (with S1 having the highest severity)

• S1 (Severity 1) -> Critical
  A critical bug causes system crash or data loss, or core functionality of a feature is being broken.
• S2  (Severity 2) -> Severe
  A severe bug causes major functionality or other severe problems; it may cause product crashes in obscure cases.
• S3 (Severity 3)  -> Medium
  Bug causes minor functionality problems. It may affect "fit and finish" of a feature.
• S4 (Severity 4)  -> Low
  Bug contains typos, unclear wording or error messages in low visibility fields.
