Banks
on the move: building new skills when migrating IS systems
Over
the past few years, it has become more and more difficult to
find a banker who is really happy with his information system.
By enlarge most bank directors or chief operations officers
complain about having an expensive and rigid Information
System. Faced with fast moving business requirements and an
ever increasing flow of new legislation, most Information
Systems find it difficult to keep up. In the post 9/11 slump,
banks struggled to cut their costs. They began to discover
that an incompressible part of the budget was spent to simply
keep their information system up-to-date. Designed in the
80’s most of their systems had been disorganised in the
90’s to be able to integrate unforeseen functions such as
electronic trading or Internet banking.
Ironically,
until quite recently, not many banks have taken any major
action to change Information Systems and to move to a more
versatile and modern IS architecture. Nevertheless, there
seems to be evidence that the situation is changing: now
several financial institutions are undertaking major projects
to migrate the very heart of the information system onto newer
and more flexible systems.
Why are these projects being undertaken now?
What strategies should be used and what approaches are
necessary when choosing a new system?
What are the major obstacles and how must banks learn
to evolve to manage such projects correctly?
A short study of several cases has revealed that there
is a definite pattern and a set of approaches that are each
adapted to different situations.
The
reasons to change an information system.
Cost
Maintaining
an in-house system or an outdated package is far more
expensive than running a modern package. However, given the
risks involved in migrating an Information System, running
costs alone may not be sufficient take such a major decision.
Time
to market
In
many cases in-house systems are badly documented, the level of
documentation dates back to a time when such issues were dealt
with lightly. Knowledge and skills required to maintain and
update such systems are beginning to be sparse.
In addition, there is a vicious circle:
given that updating old systems take too long, there is
no time left to work on the documentation. Therefore they
become more and more difficult to update, each move makes the
next one more difficult. After a while even small enhancements
can take a considerable time to implement and changing the
system can sometimes have some highly undesirable
side-effects.
Complexity
The second law of thermodynamics states that the entropy
of the closed system can only increase. In
non-scientific terms, this means that disorder will always
increase.
In
the case of Information Systems, a good initial design should
allow evolutions and new functions to be integrated in a clean
and efficient way. The trouble is that, under market pressure,
in the 90’s, major extensions or extra parts were hastily
added onto information systems. As a result, their capacity to
continue to evolve in a clean and transparent manner has been
considerably reduced. In addition, fashions and changes in
information technology have also done some damage. It’s not
uncommon to find a mixture of in programming techniques or
languages within the same system.
Considering
that all of these reasons have existed for the last 10 years,
why are banks now beginning to migrate?
Now is the time
Over the past year, there have been an increasing
number of major projects undertaken to replace in-house
systems or switch towards more standard IS platforms. This
activity contrasts greatly with the previous situation when
many were complaining and almost nobody was moving. There is a
set of reasons why the situation has changed.
During the late 90’s, the Euro and year 2000
compliance projects had a double effect. On the one hand they
prevented many banks from taking any radical steps to migrate
Information Systems (the risk was too high). On the other
hand, in some cases, they revealed just how difficult it was
to update the existing Information System.
After the year 2000, many banks launched studies to
investigate how to migrate their Information System. The
economic downturn in late 2001 slowed many of these projects
down, but their determination remained. In some banks took
another final look at incremental solutions such as partial
reengineering but, by the year 2003 to 2004, several had
already made up their mind to migrate.
Several ways, several strategies
When studying the approach that various banks have taken
to changing their Information System, it’s striking to see
that there are several very different approaches. Each one
seems to be appropriate for a specific situation. First
let’s consider two different issues:
Does IT give the bank a competitive
advantage?
Information technology can be seen as a differentiator
or not for the bank or financial establishment. For example,
in the case of a partially competitive environment, such as
that of state owned banks, information technology is not a
market differentiator.
For other banks who position themselves as
business process outsourcers, information technology is a
differentiator. Depending on their market position, Private
banks use IT to support tailored solutions for their clients.
How wide is the range of services
provided by the bank?
The other major factor to bear in mind is the range of
services provided by the bank. Private banks for example
provide a narrow range of services whereas retail banks offer
almost every kind of service. In turn this has an impact on
the way that a major migration project should be designed.
As described in the matrix above, depending on the
degree to which IT is a differentiator and the range of
services provided by the bank, the approach to changing the IS
will be very different.
Business process reengineering
approach.
Some banks provide the narrow range of services
to their clients at the same time do not rely on IT to retain
or gain new clients. Private banking branches of large
European or international banks operating in
Switzerland
fall into this category.
In such a case, the most widespread strategy is to
integrate a package that has a good market share with as
little as possible changes. In the case of the banks that we
have mentioned, in the way of packages, there is one market
leader and two challengers to choose from. As there should be
no great need to tune the system to meet specific business
processes, any sort of customisation will only increase costs
and will not provide any gain for the bank.
Depending on the size of the institution, it could even
make sense to outsource part of the operations, provided of
course that such a service is available. Choosing a very
standard package will also ensure that there are sufficient
skills and services available from third-party suppliers to
help carry out the migration and provide support for the new
system.
Integration approach
If IT is not a differentiator but the Bank has to
cope with supporting a wide range of services, taking a
package of the shelf and changing one’s business processes
may not be sufficient.
As the range of services provided by the bank grows, the
Information System invariably becomes made up of several
systems or packages which are linked together. The Bank's
information system is not homogeneous; instead it’s spread
out within several packages or systems which are integrated
together: the actual boundaries of the Information System can
become pretty difficult to define.
In this case the requirements of the future kernel of
the Information System are easier to define by looking at the
interfaces with each one of the other systems or packages. The
successful system will have to be a package that is easy to
interface with existing systems.
Toolbox approach
If IT is a definite differentiator and at the same time the
scope of services provided by the bank is narrow, it makes
sense to start by listing user requirements or functionalities
that the future system should provide.
There will almost certainly be a considerable amount of
customisation needed. In
this case, the most interesting system will be the most
flexible one.
Development approach.
Banks for whom IT is a differentiator and who
also provide a wide range of services are faced with the major
issue: IT will remain a major cost.
It’s very likely that there is no package or
off-the-shelf solution which can fit their needs. Outsourcing
could reduce costs but it could also become a major problem:
the outsourcer would inevitably try to gain new clients among
the Bank’s competitors in order to become more efficient.
Therefore IT remains an internal activity.
Each one of these approaches requires specific
skills, processes and knowledge. It would seem that the main
difficulty in migration project is being able to define which
vital skills are needed. However well designed it may be, a
project will fail if the wrong approach is being used or if
crucial skills are lacking.
Personally, if I was going there, I
wouldn't restart from here!
You may have heard the joke where a town dweller
asks a peasant his way to a major City, after a while, the
peasant calmly says “well quite frankly, if I was going
there, I wouldn't start off from here!”. It may just be a
funny story, but it also contains some wisdom.
When changing their Information System, banks
will also have to change their approach to the way that
systems are implemented and supported. It’s just as
important to know where you’re coming from as it is to know
where you're going. Pictet's experience shows how vital it is
to build up the right skills when carrying out such a project.
Identifying missing skills and processes is a key success
factor when implementing a new solution and they are not the
same for all banks.
There are many other interesting instances. For
example, some banks are engaged in full outsourcing
relationships and they could be tempted to move to a multiple
sourced solution. The idea is pretty simple: buy the best of
breed in the way of packages, integrators and hosting
solutions. It all sounds very attractive; however, their
current service levels are solely based on the availability of
an application: they have no visibility of lower level service
levels. In order to merely carry out a decent request for
proposals they will have to master entire new fields. For
example they will need to define and manage several layers of
service level agreements for which they require new technical
skills.
However attractive the solution may be, it’s
worthwhile taking some time to seriously evaluate the amount
of new skills and processes that need to be implemented first.
