Purpose The purpose of this book is to explain to information technology
(IT) decision makers those aspects of finance that most affect their
work. Most IT decision makers belong in one of two categories. Some know
a lot about IT, but less about finance; the others know a lot about
finance, but less about IT. In my experience, those in the first
category often have to make financial decisions. Those in the second
also, of course, have to make financial decisions, but about things
whose characteristics stretch the normal financial and accounting rules
up to, and sometimes beyond, their elastic limit. Among the
characteristics of IT that provide interesting challenges for financial
people are the following: - The accelerating rate of change - The short
and unpredictable useful life of IT assets - The mixture of hardware,
software and services - Upgradability - Networks that cross country
boundaries - IT jargon Asked what characteristics of finance provide
interesting challenges for IT people, many of them would answer -
"Everything". However, items in the following selection are often
particular causes of wonder: - Leasing - Why financial models always
shrink benefits but never costs - Being told that a company with a
mountain of profit is about to fail through lack of cash - Discovering
that their budget has been charged with £113 485.
