[04IN2040] Service Science

Dr. Daniel Oberle

Dr. Daniel Oberle, Senior Researcher, SAP AG, Karlsruhe, Germany

Content

As a matter of fact, the agriculture and manufacturing sectors of developed economies are on the decline, while jobs are mostly created in the service 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.

Throughout the lecture, SAP will serve as a running example since it transitions to a service company. Much like the initiator of service science, viz., IBM, the revenue made with selling services constantly increases.

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 backround for growth in service sector
  • Rationale for establishing a "service science"
  • What is a Service? An analysis from different perspectives
  • Service-oriented Architectures
  • x-as-a-S phenomena: Software-as-a-Service, Platform-as-a-Service, Infrastructure-as-a-Service
  • 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

Required Knowledge

General understanding of Unified Modelling Language (UML).

Acquired Competence

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.

Slides

The Slides for the lecture can be downloaded at the following links. The authentication will be provided during the lecture. Alternatively, you can ask for the authentication at oberle [at] uni-koblenz.de

Examination

Instead of an oral or written exam, the expected outcome will be a USDL description of a service of your choice. The description must be created with the Linked USDL Editor and meet specific criteria as will be explained during the lecture.

Groups of 2 or 3 are allowed. The deadline for submitting the corresponding .usdl file will be negotiated during the lecture.

The deadline for submitting the corresponding .usdl file is the 26th of July.
