The document discusses how the planning process is being transformed by incorporating data from the Internet of Things (IoT). It outlines how IoT connects products, machines, infrastructure and people, generating vast amounts of new data. This data from across the entire value chain can improve planning accuracy by removing latency and allowing events to be predicted. The reference architecture shows how IoT data on logistics, transportation, weather and more can enhance planning effectiveness. The key takeaway is that tomorrow's planning must leverage IoT to adapt in real-time and remain agile in increasingly complex operating environments.
