On January 2018at 8:07 AM , a false missile alert was issued in Hawaii, causing widespread panic. The error was corrected 38 minutes later.

BALLISTIC MISSILE THREAT INBOUND TO HAWAII. SEEK IMMEDIATE SHELTER. THIS IS NOT A DRILL.

This incident brought the design of the HIEMA (Hawaii Alert Management Agency) alert system UI, shown below under scrutiny.

As a 20 minute exercise, design a new alert system UI that is less error prone. You may use our mockup of the actual alert system UI. See the results.
