NGOSS
New Generation Operations Systems and Software
• Define and rationalize the new generation of
architectures and frameworks
• NGOSS™ is the term the TMF uses to describe
• a “loosely coupled” distributed component
architecture
• along with “business aware” application
components
• upon which ICSP business can run.
• The components interact through a common
information bus
• The components can be programmed through the
use of a process management tool to control the
business processes of the service provider using the
functionality provided by the components.

Paradigm shift of Business Process Analysis
• Operator view point  Customer view point
• Enumeration of conventional process  Top down process
analysis
• Individual ,isolated process
•
Closed, Internal process
and partner
 Process flow through
 Cooperative process with customer
• Presume matured technology  Exploit prospective technology

New Business process
Optimized Process
 Agility process for daily business
transformation by process components.
based flexible BPM
31
Check points of OSS development
• What advantage customer can expect ?
• The business process developed is applicable in the market ?
( Modify process to meet market products and trend)
• How flexibility and expandability are guaranteed to meet unknown
change in short time ?
• Can be interface clarified on system ground plan ?Can related
systems agree it ?
• List up and evaluate reusable /available components and tools ?
• Evaluate current/future technologies ? Deployed technologies will
become mainstream ?
• Can you sell the developed package ?
• Can you release within 6 months ?
32
OSS Evaluation Point
1. Term :
Faster, Cheaper and Higher Quality  6 months rule
2. Engineering :
How designed rather than what can do
Deployed( Selected) Architecture, Components,
Technologies ( Web, XML,CORBA,EJB etc.)
3. Interoperability :
Proof of “Market In” Products Not Built But Buy , If
Built Must Sell it
4. Flexibility ( Agility ) :
Quick Response to Specification change( Modification)
2-3days for process change, one week for AP

Requirements to SE/SI group
for analysis and design
• Vision and insight to grasp business as a whole.
• Foresight to depict what is essence and
substantial.
• Ability of abstraction ,description and
presentation .
• Engineering ability to embody concept to
products.
35
Project Management
• Control of CQD(Cost, Quality and Delivery)
Does work , do things right
• Manage CQD, Technology, User support,
Change management , Time in Market etc.
Does contribute , do right things
36
Project Management
• PMBOK(Project Management Body of Knowledge)
5 basic process group:
Initiating. Planning, Executing, Controlling, Closing
9 knowledge areas:
Integration,Scope,Time,Cost,Quality, Human Resource,
Communications, Risk,Procurement,
• PMP(Project Management Professional )qualification
by PMI( Project Management Institute /USA)
37
Note of project management
• “Object oriented “ is a methodology effective only
when project team well understands what is it.
• Only the objects which intentionally developed for
the purpose of reuse can be reused.
• Water fall model can be applied to the objects small
enough that one person can understand.
• Take enough time before starting programming.
• High technologies soon become consensus and low
technologies in the next step.
38
Case Study
• NTT Service front support system
• Fujitsu Service Management system
( FLEXER –SM)
39
Target of Service Front
Issues :
• In the explosion of variety of services, heterogeneous
technologies and competition
• Urgent to Establish total customer center for any services and
claims
• By Realizing quick and accurate response to customers for
24/7/365
Kaizen :
• Develop Business process and OSS to concentrate necessary
information to service front operator -> networking
• Training and team work reinforcement to operators

41
Business process ( networking and organization)
• Reform of “113” test center of service claims to total
customer service center
• Responsible HQ department create DB of service
/products information accessible from any center
operators. ( visual and text )
• Network status information is to be reported to /can be
accessed by the operators for both intra office and
nationwide events.
• Share the knowledge and useful experiences among
centers by email exchange, accumulate knowledge DB
and help desk.
• Rule based control of information handling for security.

OSS development
• Received the order at April 1993 and introduced the
OSS to 90 main centers at March 1994
• Process analysis ,design and technology assessment
for 6 months collaborating OSS developers and business
practitioners( operators)
• Software development for 6 months. Initial OSS cut off
( first introduction ) started January 1994.
• Deploy Sun Solaris , embedded mail function and
package middleware.
• Deploy end user programmable GUI and local DB.
