IMPACT: A false alarm warning Hawaiians of an incoming ballistic missile on Saturday
ROOT CAUSE: badly designed user interface
ROOT CAUSE: employer pressed button labelled ‘missile alert’, instead of the one next to it marked ‘test missile alert’
COMPANY RESPONSE: added a “cancellation button”… HEMA has also added a requirement for a second person to confirm the message to be sent
