| Challenges in Application
Integration Today – This illustration depicts the
complexity and the number of domains involved in
application integration within a typical
bank. |

The obvious challenge is getting the
independently designed systems and various disparate
technologies to work together. The real challenge is
getting all the people who represent the wide and varied
parts of the enterprise to work together. A typical bank
has a least 6 main business areas, 8 delivery channels,
4 different computing platforms, 4 service providers, a
few software environments, some recent technologies and
a network / communications group. Added together, this
makes at least 24 different domains. Together with the
types of people active in projects, maintenance, and
support, who vary from full time staff, contractors,
software suppliers and consultants, this is a highly
complex situation - and it is the normal state of a
typical bank today, and not an exception.Today, we
attempt to manage and execute multiple projects, enhance
and support the entire IT facility in the same manner as
we have been doing it for the last 2 decades.

People are
expected to work together in an integration project. We
tend to think they work well together. However they are
constrained by the current process of integration
methodology. The problem is not obvious, in individual
parts of the integration work. Individual parts,
typically does not present themselves as a
problem.However when two or more of these parts, are
integrated together, the disparity between the parts
(unknowingly or otherwise) contributes to issues that
have the propensity of permeating the whole. In
integration projects, this is a problem of the
collective, and is a management issue. This collective
problem in a typical enterprise, however manifest itself
in different forms like: escalating costs, shortage of
skilled resources, long product development
cycle etc. |
