Why can’t we just use SMS and pagers?


SMS and pagers have the following problems:

  • Lack positive message acknowledgement/accountability
  • Delivery success and time can be inconsistent
  • Limited content (message size and unstructured text)
  • Must acknowledge using a different device and/or application, thus hindering collaboration
  • Must use another device or application to research the alarm. No easy way to interact with the SCADA system and no real-time query
  • Does not use GPS to determine notification recipients
  • Understanding the overall situation requires reviewing multiple messages to construct a mental model
