The Future Internet envisions a ubiquitous world where available services can be easily discovered and coordinated so as to fit users needs. Service choreographies will play a central role in this vision as an effective means to allow heterogeneous services to suitably collaborate. This deliverable defines the CHOReOS Dynamic Development Process Model by refining and completing the artefacts/ activities and the relationships among them already sketched into the DoW (under the WP2 description), and conceptualized by the the CHOReOS conceptual model [CHO11b]. The process model is an abstract and simplified description of what will be the actual CHOReOS software development process to be defined at M24. The process model describes the "strategy" to be used during the choreography life cycle from design, to development, to maintenance (and hence from static, to runtime, to evolution). The model is made up of activities, common to (almost) every process, but structured in a particular way (i.e., the "CHOReOS way"), hence distinguishing the CHOReOS development process from others.
