It is always said about decision-making that you need the right information
for it. Well-aggregated, correct, complete, up-to-date, accurate and
verifiable to boot. Junior executives even think they need a great deal
of information: if I know everything, I will be able to make the right
decision.
Suppliers of software packages think that top executives are only able
to think in three-dimensional, multicolour pie charts or other fancy
diagrams, made accessible via a hierarchy of simplistic icons.
The IT industry has plunged greedily into this supposed need for information
by developing MIS, DSS and even EIS, nowadays. EIS is an accessibility
system for raw data of various types, with many navigation possibilities,
while the origin of the data is transparent to the user. EIS sees to
the aggregation of data on different levels.
It turns out, however, that top executives need only little information.
They base their decisions on intuitive signals and use the information
to support their decisions afterwards. The latter seems to be necessary
to persuade subordinates of the plausibility of the decisions in question.
The point is that we are not used to follow leaders anymore; we only
start moving if we understand the plausibility ourselves.
Decision-making, however, is not exclusively an executive task. All
of us make many decisions every day. Decisions based on information,
preferably of high quality. These form the crux of the matter: information
and quality. Information, or so we are taught, is a body
of data that improves the knowledge. But what is knowledge? And what
is improvement? Improvement of our functioning as a human being or improvement
of the ego? In practice it turns out to be very difficult to find the
right measure for our information need.
The value information has for decision-making lies in the reduction
of insecurity, which is the next obstacle. We, people, have a great
intrinsic insecurity, because we have forgotten who we really are. Identified
with everyday routine, we hardly realise this. Because of this great
insecurity, it is difficult to determine what the right information
is for the problem at hand, both for an individual and for those who
are trying to help. As a consequence, all kinds of data are acquired
or offered. It is silently assumed that among all those data surely
the information that is necessary must be present somewhere. This bears
close resemblance to the proverbial needle in a haystack, and such a
mass of data hardly has any decisive value. At best, it serves an activity
of the ego that collects data for possible future events, on the pretext
of. It doesnt hurt to know. Because of the mass of
data and the obscurity of it, we think that decision-making itself should
also be automated. Such automation would imply that the decision-making
process always takes place according to a fixed pattern, thus leading
to a depersonalisation of our society.
The quality of decision-making is therefore highly influenced by the
quality of the automated information. Moreover, the quality of decision-making
ought not to be determined solely by financial and economical considerations,
or by technical considerations. It should rather be expressed in terms
of progress of human development. If only financial and economical or
technical factors play a role, our society will sink to a merely mechanical
level.
Anyway, an executive who bases his decisions only on management information,
might as well be replaced by an intelligent computer.
