Interoperability general view
  • Oxford able to operate in conjunction.
  • Webster ability of a system to use the parts
    of another system
  • Generally, Inter-operate implies that one
    system performs an operation on behalf of (or
    for) another system.

4
Interoperability - IEEE Definition
  • Ability for two (or more) systems or components
    to exchange information and to use the
    information that has been exchanged

IEEE standard computer glossaries (1990)
5
Interoperability software view
  • Two co-operating software can easily work
    together without a particular interfacing effort.
  • It also means establishing communication and
    sharing information and services between software
    applications regardless of hardware platforms.
  • In other words, it describes whether or not two
    software that were developed with different tools
    and from different vendors can work together.

6
Interoperability vs. portability
The concept of interoperability is closely
related to the concept of portability. TOGAF
defined the portability as
  • the ease with which a system, component, data, or
    user can be transferred from one hardware or
    software environment to another.
  • a quality metric that can be used to measure the
    effort to transport or convert the software for
    use in another environment

Portability is the ability of data or system to
be moved, and interoperability is the ability of
software or systems to understand and use
information coming from other software or
systems.
7
Interoperability vs. interchangeability
  • Interoperable ? interchangeable
  • Interchangeable
  • gt replace a system or component to provide a
    same service with an equivalent behaviors (ex.
    response time)
  • Interoperable
  • gt simply ability to exchange service without
    necessity to have the same behaviors.

8
Interoperability system view
  • Reversibility Even if the implementation of the
    interoperability between partners leads to an
    adaptation or a modification of the systems,
    these systems have to be able to come back to
    their initial state at the end of the
    interoperation

Interoperability vs. integration
  • Interoperability has the meaning of co-existence
    and co-operation, while integration relates to
    the notion of collaboration and uniformalisation.
  • In (Vernadat, 1996), interoperability is defined
    as the ability to communicate with another system
    and use the functionality of the other system
  • gt Interoperability communication
    interaction
  • However, integration is more large and broad
  • gt Integration communication co-operation
    co-ordination

11
Interoperability vs. collaboration
  • Interoperability ? collaboration
  • Interoperability
  • gt has no direct business mission / goal
  • gt does not directly solve any business problem
  • Two interoperable enterprises may not have any
    collaboration project
  • Two enterprises in collaboration may have serious
    interoperability problems

12
Enterprise interoperability
Ability of interaction between enterprises (or
part of it). The enterprise interoperability is
achieved if the interaction can, at least, take
place at the three levels data, application and
business process with the semantics defined in a
business context
