UNDERSTANDING DEMAND FLUCTUATIONS
Since the work that creates the demand comes from the business, ITIL
recommends that to understand how demand fluctuates we identify patterns of business activity. There is clearly a relationship between business activities and the consumption of IT resources. Our challenge is to understand that relationship well enough so that when the business shares its plans and forecasts with us, we can predict the impact on our resources. This in turn will tell us which resources need to be replaced or upgraded and when, so that we can cost-effectively plan and budget our IT spend.
