Customer Service System
From Wikipedia, the free encyclopedia
BT's Customer Service System (CSS) is the core operational support system for BT, bringing in 70% of income for the company. BT rolled out CSS nationally in 1989 and provided an integrated system for telephony — order handling, repair handling and billing.[1]
BT Customer Service System (BT/CSS) was developed by LogicaCMG in 1984, costing £1bn to implement, representing the largest computer project undertaken in Europe and the largest integrated database in the world, at the time.[2]
BT’s CSS databases hold over 13 Terabytes of data for 23 million customers. Running on 28 Mainframe images, CSS supports an online population of over 40,000 users generating over 230 million transactions per day.[3]
