2. Enterprise Total Computing TECHNOLOGY SERVICES Sprint Proprietary Information 18/10/99 Slide 2 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

3. Enterprise Total Computing TECHNOLOGY SERVICES Sprint Proprietary Information 18/10/99 Slide 3 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

4. Enterprise Total Computing TECHNOLOGY SERVICES Sprint Proprietary Information 18/10/99 Slide 4 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

6. Enterprise Total Computing TECHNOLOGY SERVICES Sprint Proprietary Information 18/10/99 Slide 6 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
