Return on Investment 77

1). For these non-duplicated transactional data, it is easily
accessed as they have a unique storing location.

Once this surveillance strategy of the Information System
and its underlying IT systems is understood, what is the
return on investment of an MDM? What budgetary promises
are directors and board of directors ready to agree to in order
to better manage operational risks?

MDM becomes a kind of insurance against risks. Since IT
is present in all the decision processes and operational tasks,
the surveillance system, on condition that it has correct and
reliable data in an MDM system, offers a considerable risk
detection capacity in real time, and a very rapid adaptation
in face of changes.

4.4. The financial gain of IS transformation

We have already seen how a company must act to
transform its IT, worn out by time and dealing with
complexities too great for it to handle (see Chapter 2). The
use of data repositories (MDM), of rules (BRMS) and
processes (BPM) is the key to this transformation. We will
now study the financial evaluation of these repositories. To
justify the necessary investment to the transformation, a
new asset must emerge, the valuation of which is greater
than that already in place.

But, how do we estimate the value of IT and, while we’re
at it, the whole Information System? This question is not a
new one and has never found a satisfactory response. We
need one, however, as without it all idea of a transformation
is stopped dead in its tracks. The answer does exist: it is
found in the genes of the transformation approach that we
are describing. To understand it, we must first look at the
strange overlap, favored by time, between an Information
System and its underlying IT systems.
