EXECUTIVE SUMMARY
Today’s players in the Information, Communications and Technology (ICT) industry -
including service providers work operators - are facing unprecedented
challenges to simultaneously:
• work operations costs;
• Introduce new working equipment faster and with reduced
integration tax;
• Introduce munication services more rapidly and adjust their
functionality in response to changing market needs; and,
• Improve customer satisfaction.
Each of these challenges are in and of themselves daunting; however, taken
collectively, they require that service providers work operators address not
only the technology that they use for Operations Support Systems but also the way
that they specify, develop and deploy those systems. To use a manufacturing
analogy, they need to focus not solely on the product, but also the production line
and how it anized and operated.
There is growing consensus that the industry needs to move towards a service-
oriented ponent based solution allowing for re-use and a lowered integration
tax. However many of the published methods assume a green field situation and a
single technology base.
For established operators, and even new operators, integrating mercial
off the Shelf packages using existing methods are not easily realizable.
The TMF has developed a technology neutral architecture NGOSS™(Next
Generation Operations Systems and Services) that is distributed, service-oriented
and ponent based implementations. This architecture can be
specialized to use a variety of base technologies (., Java, XML, CORBA). Much of
the published material to date has focused on defining what NGOSS is.
The NGOSS Lifecycle and Methodology project was established to provide the
industry with mon framework o
