What were the challenges that XXX wanted to resolve?

XXX had three clear requirements:

First, XXX wanted to be commercially very agile and deploy fast new commercial initiatives. When competitors launched a promotion or a new product, then XXX also wanted to be able to react immediately.
With the previous legacy systems, it took XXX at least three weeks (including testing) until a new product or promotion could be introduced to the market. With YYY, this is executed within a definitely shorter term.

Second, XXX wanted a scalable solution, meaning that a high increase of complex operations could be executed fast and simple. With YYY, you just add another server if that would be required. Fast and simple.

Third, XXX wanted a system that supports very efficient operations such as ** fast billing runs **.
