Ask yourself: - Are IoT devices automating and streamlining tasks in my daily life but not my daily business practices?  - Am I still relying on analog practices to facilitate operations throughout my supply chain? - Am I uneasy about the security of my data (i.e., relying on conventional data loggers or other easily misplaced and/or cumbersome devices)?
