This document discusses how Internet of Things (IoT) changes product design and product teams. It notes that with IoT, product design shifts from a traditional linear model (develop, make, deliver, use, maintain, dispose) to one where products can be improved over time using data from customer usage. This allows products to be refined with new functionality, proactively resolve issues, and engage users throughout the product lifecycle. It also provides an example of a real-world IoT healthcare system that uses sensor data to provide personalized, preventative care rather than just treating illness. This shifts care to detecting issues early and preventing emergency room visits.
