Episode 7:
Ending the Dictatorship of the Road Map

 

In CBS
The bank lives under the dictatorship of its “road map”, and when a new functionality is needed, the bank's technology is such that long timescales and significant costs are unavoidable. Each change brings with it a significant risk of related malfunctions in functions or trees that have nothing to do with the domain of the desired new function. The various layers of improvement, the different languages sed, and all the changes made over the years inevitably give rise to side effects that make any new project very complex. It is this that explains the long timescales and significant costs of new developments.

 
 

In DBS
In contrast, the platform has been designed to evolve. A new module, a new function, or any other improvement can be implemented in no time at all, at therefore incomparable cost.


Conclusion


Agility and adaptability are probably the most important qualities of these new architectures, because nobody knows what the needs of the bank will be in two or three years' time. If it takes two or three years to meet new needs, it is clear that one runs the risk of incurring chronic obsolescence.
