Service Definition
“a change in the condition of a person or a good belonging to some economic entity brought about as the result of the activity of some other economic entity ”.
[ Chesbrough, H. and Spohrer, J, 2006]

Service systems Definition:
“value-coproduction configuration of people, technology, other internal and external service systems, and shared information”.
[ Spohrer et al, 2007]

Network of service systems Value creation network Definition:
“an organizational network that is defined as a group of several autonomous organizations that work together to achieve not only their own goals but also a collective goal ”.
![Page 6: Vi 1 Presentation Iess 2010 Thang Le Dinh Feb 18](https://reader034.vdocument.in/reader034/viewer/2022051513/5479d5ff5906b5fd348b4613/html5/thumbnails/6.jpg)

Network of service systems Organizational network
A hierarchy each part is exactly defined in order to
perform a specific function.
A market an agent can provide products and services
to other agents.
A network its members work together by
communication, based on trust.
[Powell, W, 1990]

Information-driven approach Our approach
Fundamental characteristics: Services are Information-driven
focuses on the creation, the management and the sharing of information at the informational level conforming to the network configuration

Conceptual framework Network of service systems level
Service specification: depicts what are networks of service systems and the value co-producing between internal and external service systems.
Service system level Service creation: describes what are service systems and
the roles of people, technology, and shared information
Service level Service operation: presents what are provided to
customers and how they are provided.

roles Service profiles:
dependent & independent, deliverables, agreement
Network configuration, governance form
Shared information

Conclusion Conceptual framework
Network of service systems level (Service specification): Entities, Roles, Governance, Services
Service system level (Service creation): Shared information, Technical implementations, Resource
Service level (Service operation): Static, Dynamic and Rule aspects
Contributions A foundation for a thorough understanding of Services,
Service systems and Networks of service systems based on network configuration and shared information.

Future works
Implementation of the conceptual framework Networked service management system (NSMS):
Implementation of the framework in the service- oriented architecture (SOA).
Experiencing the NSMS with SME services
Integrating the framework with specific categories of services Customized services as projects
Applying the PMI framework for Quality, Performance and Risk management

Introduction Three sectors of the economy
Primary sector: mining, agriculture and fishing
Secondary sector: manufacturing
Third sector (tertiary sector, service sector or service industry): services
Actual situation Service sector has dominated the global economy.
It consists of 75 percent of the gross domestic product (GDP) of developed countries and employs more employees than other sectors

Service science A new science of service systems ?
applying scientific understanding, engineering discipline, and management practices to understanding and working with services systems
SSME Service Science, Management, and Engineering An interdisciplinary approach introduced by IBM to
describe Services Sciences Universities and companies have begun to act on the
need for service science or SSME
