Over recent years we have seen a number of trends among large corporations trying to get clarity on their real IT costs and squeeze efficiency from their resources. It is interesting to compare some of the approaches, and how they restrict the value that can be gained.
Some companies tried to ring-fence their IT by creating a management services company, forcing financial rigour on the supply of services. Great idea… or was it? Clearly there were some benefits from the transparency on what was being purchased (at least in theory), but there were also management overheads and investments needed to gain this rigour; it is unclear whether or not these were ever compensated for in efficient savings.
