Independent
Portfolio Analysis The following
paragraphs are based upon a SeaQuation paper prepared for and published
by the IT Governance Institute as part of their ongoing research into
best practices for IT governance. Associates and key staff members of
SeaQuation (John Thorp, Eric Guldentops, John Spangenberg and Paul Williams)
were amongst the founding fathers of the complement to the well-known
CobiT standard, named ValiT (Value of IT). ValiT will be published by
ISACA by June 2005. Given
its ING origin, it is only natural that SeaQuation adopted a bankassurance
perspective on IT and used mainstream Financial Economics to calculate
the Alpha (excess return on IT) and Beta (standard deviation of expected
return based on loss statistics) of IT investments. The Capital Asset
Pricing Model e.g. contributes to determine the risk-adjusted yield
of IT investments against the expected return of more familiar asset
classes within the corporate investment portfolio such as real estate,
M&A, total shareholder's return of company stocks, commodities,
private equity, cash, hedge funds or governmental bonds. SeaQuation's
bankassurance approach provides the common denominator enabling valid
comparisons between the cost, benefit and risk of each of these investment
categories and to estimate the opportunity cost. |
