From Mr John Stanning.

Sir, It’s not surprising to read that “big spenders reveal they know little about the value of IT assets” (report, October 1). First, most equipment now has IT embedded in it, so the definition of “IT spending” is fuzzy. For example, modern process-control devices have embedded computers, but are they counted as “IT” ? There was a time in the 1980s when some companies had more computing power in the microprocessors built into their company cars than in their data processing departments!
