I see three inter-related threads for process / IoT cooperation and success:
Personal Internet of Things: IoT provides customer data to drive customer satisfaction processes. Using location information, details from multiple reporting "things", and customer opt-in, a "personal process" can collect the details needed to look for patterns, offer suggestions, and make life work better. Current "things" like fitness trackers, smart phone social apps, and tags/monitors in cars, appliances, cameras, etc. provide a picture of the owners' lives. As connected personal devices become ubiquitous, we are seeing proposals and processes for leading a "monitored life." In the hands of businesses (whether a bank, retailer, social software company, or advertiser) with their own agendas, this has high value but is also potentially intrusive and creepy.
Business Internet of Things: IoT provides real-time monitoring of machines, materials, and objects that participate in a process, to ensure a process is on track and to remediate problems in materials and machines . We already see this in manufacturing, farming, supply chain, and health care, and it's moving into many other industries and workplaces. IoT can supplant (or replace!) all kinds of human monitoring and, with the proper "intelligent" BPM software, can perform troubleshooting, service scheduling, and even repairs without intervention.
Government Internet of Things: IoT provides a much more connected infrastructure for society as a whole. Security cameras, toll and parking controls, access cards, and biometrics are exploding in every major city worldwide. These make our lives easier, but they provide an almost continuous stream of information on our whereabouts and activities to government at every level. Just as we worry about providing too much information to commercial interests, we are chilled by the big brother possibilities of Government IoT. I think the next decade will see a huge debate and the beginnings of new (process-based) approaches to protecting our privacy while improving services and security.
