However, achieving such universality of measurement is going to take considerable effort in the IT industry (see, for example, Val IT). IT investments are not liquid, like stocks and bonds (although investment portfolios may also include illiquid assets), and are measured using both financial and non-financial yardsticks (for example, a balanced scorecard approach); a purely financial view is not sufficient. Finally, assets in an IT portfolio have a functional relationship to the organization, such as an inventory management system for logistics or a human resources system for tracking employees' time.
