Case Study Vodafone

The Client
In December 1989 Vodafone Germany received the first private license for a digital mobile telephony network in Germany. A unique success story began: With now more than 34 million customers, more than 8 billion in sales and more than 9.000 employees Vodafone Germany is one of the biggest and most modern telecommunication providers in Europe.
Today Vodafone Germany stands for single-source communication:

• mobile telephony
• fixed network
• fastest data services

Vodafone Germany belongs to the Vodafone-Group and thus to the worldwide biggest mobile telephony company with more than 252 million customers.

The Challenge
With its customer information and billing system Vodafone Germany operates one of the most complex and powerful billing systems. Due to permanent new requirements for marketing, sales and/or operational reasons, at fixed intervals several times a year, new releases with added or altered functionality are being produced.
There are many satellite systems around this customer data and billing system,

• to proceed the business cases in the regions in the more than 1.600 shops and partner agencies
• to swap particular functionalities into own applications, e.g. campaign management (customer bonding system) or incentive engines (reward for particular customer actions)
• to enable private and business clients to execute the essential business cases via internet

In addition Vodafone Germany operates one of the biggest and most complex data warehouses.
For this gigantic IT-landscape an enormously high level of quality management is necessary.
