Results
•Process definition by using TOM
•Introduction of PKG software
•Introduction of open systems
•Decentralization
•Rapid development and deployment
•Rapid introduction of new services
•OSS development cost reduction

Challenge going forward
Quality
•Rich scalability
Cost
•OSS development cost reduction
further
improvement
Delivery
•Rapid development and deployment
•Rapid introduction of new services
and
Quality
•Strengthen Customer Retention
•Faster, more efficient operations
increase revenue
decrease expenses
7
Approaches and Expectations
vision
TMF approach
sharing information of common
•NGOSS
interest between SPs,
•eTOM(GB921)
producing requirements that will
drive the NGOSS program, etc.
•SIM(GB914)
•SID(GB922), etc.
•Service Provider Leadership Council
NTT-W approach
To be more
competitive..
•Simplification of OSSs
•Loose integration among OSSs
•Revival of “internal development”
something else?
8
Simplification of OSSs
Simplicity of supporting business process
Simplicity of business logic/function logic
development of
service independent
simple OSS
Simplicity of architecture
Simplicity of database schema
customization into
service dependent
simple OSS
introduction of
service-A
simple OSS for
service-A
introduction of
service-B
simple OSS for
service-B
ref: M.Koyabu, H.Ishida, M.Takano, “Development of successful OSS for IP based telecommunication
Services” TMW, Nice, France, SWD4, May 2002.
9
Loose integration among OSSs
Front end integration platform
Back end integration platform
ex. EIP
Autonomously
Decentralized
Operation
Support
Systems/subsystems
ex. EAI,EII
10
Revival of “internal development” (1/2)
back ground
•Difficulty in making consensus with SIers
•Further shorten upgrade cycles in OSS
•Emergence of sophisticated integrated design environment
•Eclipse, etc.
•Harsh competition with other SPs/CLECs

• OSS development evolution
– making steady progress but not enough,
• How to drive/promote the evolution
– TMF approach
– NTT-W approach
– something else?

Thank you for your attention.
appendix
Problems in introduction of COTS
investigation phase
design/making phase
・difficulty in optimal selection
・difficulty in “fit and gap”
・high cost
・no warrant in continuous
support
・insufficient localization
・large add-on coding
・unclear specification
(black black box)
・conflict with other COTS
development life cycle
running phase
・necessity of large hardware
resources than expected
・insufficient quick response
・insufficient performance
・functional gap from expected
test phase
・debug of COTS
・add-on coding for avoiding
bug of COTS
・long period of test phase

Classification of data reference among OSSs
