In the time it takes you to read this sentence, millions of payment transactions will have occurred.
Speed, throughput and decision accuracy are everything in the payment industry. The typical payment transaction authorizes within 50 milliseconds. This means that shifting customer demographics and new payment products and channels -- mobile devices, among others -- create significant challenges for the IT organizations at major payment networks such as Visa, MasterCard and American Express.
Unfortunately, the large legacy of IT infrastructure and networks stands as a potentially immovable object before the bullet train of ever-changing customer needs. A transformational business model is required to service customer requests consistently in their channels of choice.
A detection-oriented approach is key
A large number of changes are being introduced into major systems on a daily basis. Because of this, a drift develops between the CMDB and the run-time environment. To mitigate the drift, IT processes such as software development life cycles and the Information Technology Infrastructure Library (ITIL) must proactively maintain the CMDB and all related architecture repositories.
Until we had this proactive type of process in place, some IT organizations with which I have been associated had to undertake huge manual reconciliation and clean-up activities -- multiple times. This led to a loss in confidence of roadmaps and hindered the IT transformation.
