The value of belief
If you believe and act on business estimates of the value of IT, organisational pressures will drive the figures to be accurate.
In last week's newsletter I suggested that the most accurate way to estimate the business value of IT is simply to ask the business owner of each system what the system is worth, and believe and act on whatever answer they give.
We can use these estimates of value to help us manage IT. We can use them to decide which systems to keep, which to discard, and where to invest. We can use them to show which IT creates profit, and where IT is an unjustified cost. We can use them to value IT projects - the project value is the difference between the value of the IT before the project and the value of the IT after the project, multiplied by a suitable payback period.
Some would argue that this approach is an abdication of the IT organisation's responsibilities. I disagree. The IT organisation has broad responsibilities, but it can not be responsible for downstream business value. Openly stating this places the responsibility more clearly where it belongs.
Some would argue that this approach is too difficult. I disagree. In simple cases you can estimate the value of IT by estimating the cost of the manual alternative. In entirely IT-dependent processes you can estimate the value of the IT as a proportion of the value of the entire process. If the benefits of IT are intangible, you can set a notional value to counterbalance the very real costs of IT. Even estimating that an IT system is only worth its running costs is useful for management.
The beauty of this method is that it encourages business managers to estimate accurately.
Using the estimates to show how IT creates profit, and to show which IT systems are not worth their costs, encourages meaningful discussions about IT value. It encourages business managers to give the best answers they can: well-researched, cautious, but not too low. This is the best mindset for valuing anything, and gives the best figures for managing IT.Next: Can I have it in Excel?
