Introduction

Sprint had a number of projects during the 1991 through 1994 time-period aimed at
unifying the architecture used to build computer systems.

Drivers
 Cost of duplication of data and functions in computer systems
–
Development for each product or service
–
Multiple order entry systems - voice and each data product (X-25, FR, IP, ATM)
 Cost of maintaining interfaces between systems
–
As services become more complex, interface maintenance is significant drain on resources
 Ability to manage multiple services over ATM
–
Frame Relay over ATM, IP over ATM, Voice over ATM, Voice using ATM
 Fault Management needs to be able to correlate alarms from all network elements
–
Separate systems for each element type require manual interpretation of alarms
 Need for very fast service (product) development
–

First to market gets a disproportionately large share of sales
Focus - 2 main categories
 Technical architecture - how systems are built
 Functional architecture - grouping like functions - build each process once

Data architecture depends on these being defined first

Functional Architecture

My involvement has been with the functional architecture for which there are a
number of names:
 Enterprise Total Computing - ETC
–
My preference - its scope is all functions except Human Resources and Stockholder Services
 Integrated Service Management - ISM
–
Used by Sprint associates since 1993 - we were unaware of the GE-Bull product, ISM.
–
Misleading as many think it only includes network and element management.
 Communications Business Model - CBM
–

Used by those Sprint developers responsible for including new developments from both TINA and
Telemanagement Forum.
2 Primary Approaches
 Top down - business developers saw many functions that used a single network
 Bottom up - the traditional TMN pyramid, heavy at element level and ignoring business complexity

Merged Functional Architecture - ISM - December 1994

Computing
Components

Standards based whenever possible
 Industry standards for common objects
 Open systems interfaces
 Electronic bonding for network management interfaces

Functional Architecture
 Grouping of processes by function to simplify reuse of common procedures
 Will be replaced by an Object Architecture when analysis and design are sufficient

Data Architecture
 Enterprise Object Model developed and being tested and improved

Program View - grouping of functions for re-engineering by:
 Service Creation
 Service Delivery
 Service Assurance
 Billing
 Asset Management
 Planning

The TINA Discovery

A Sprint colleague met Hendrik Berndt in 1994 or 1995
 Have you looked at TINA?

We looked at TINA
 Many man years of expert work was available for us to improve ETC
 The documentation included the reasons for decisions:
–
Why items were in or out
–
What was need to complete them (e.g. IDL --> ODL)
 Many of our conclusions were reinforced
 Most of it made sense
–
We discussed a few problems with Hendrik who was often in KC
 Many carriers with whom we interface were TINA-C members
–
Using TINA would help when developing future interfaces

Our enterprise object model incorporated TINA concepts

We made some changes to our functional architecture
