Learning Outcomes
The lecture will convey a basic understanding of the socio-economic and 
business aspects underlying service science. The lecture also aims at 
providing an insight into the various attempts for defining "what is a 
service?" The lecture will discuss the touch points between computer 
science and service science, including service-oriented architectures, 
xaaS, and formal description of services. With respect to the latter, an 
in-depth explanation of the recent Unified Service Description Language 
(USDL) will represent a major part of the lecture.
As a matter of fact, the agriculture and manufacturing sectors of 
developed economies are on the decline, while jobs are mostly created in 
the services sector. The lecture will explain the socio-economic and 
business aspects underlying this phenomenon, that basically led to the 
call for establishing a new discipline called service science.

Since the term "service" appears in many disciplines (particularly in 
business economics and computer science), the lecture devotes a 
significant part for providing an insight into the various attempts for 
defining "what is a service?"

The lecture then dives into the touch points between computer science 
and service science, including the explanation of service-oriented 
architectures (SOA), the x-as-a-service phenomena as well as the 
Internet of services.

A major part of the lecture will be taken by the formal description of 
services for the purpose of trade and delivery in the Internet of 
Services,  Here, SAP Research and partners developed the Unified Service 
Description Language (USDL) which allows to capture the business, 
operational and technical aspects of any service on the human to 
automation continuum.

More specifically the lecture will cover:

  * SAP and services
  * Socio-economic background for growth in service sector

·Rationale for establishing a "service science"

  * What is a service? An analysis from different perspectives
  * Service-oriented Architectures
  * x-a-a-S phenomena: Software-as-a-Service, Platform-as-a-Services,
  * The Internet of Services: systematic use of the Internet for new
    ways of value creation in the service sector
  * In-depth discussion of Unified Service Description Language (USDL)
  * Service Description Approaches: State-of-the-Art overview
