The Internet of Things
Internet influences the way we make business
Future internet not limited to humans
Kevin Ashton identifies objects in supply chains by RFID
Todays internet covers mainly human created information
Smart devices overtake information provision of things

Internet of Things and BPM Systems?
Different history and different central concepts
Promising vision
Thousands of sensing and actuating devices execute parts of business processes
Devices could overtake process responsibility
Smart devices and human performers could interact or compete
How does the IoT with its main building blocks fit in the traditional
business process environment?

Some Background
BPM a systematic approach to capture, execute, document, monitor, and
control
Creation of business process model basis before automation
Business process composed out of tasks
Tasks can be implemented by exchangeable services
Traditional web services / IoT services
Target: Provision of IoT-aware Business Process Model
Evaluation of existing notations concluded to use BPMN 2.0

Summary and Outlook
Lack of modeling concepts when representing and automating IoT-aware
business processes
New BPMN extensions for IoT device and native service:
Graphical representation
CMOF metamodel
XSD metamodel
General semantic shell
Prototype and use case implementation in Future Retail Lab
Broader application of IoT Reference Architecture
Stepwise implementation and validation
