Managers become attached to IT because IT suppliers sell the notion that the systems will provide high quality information which will enable better decision-making.
Detailed reporting of information at all levels and with increasing levels of detail is something of a command-and-control thinker’s utopia.
What managers fail to realise is that these IT systems most often serve to make matters worse by increasing attention to output.
The first thing anyone should do when looking at new IT systems is address the following question:
What data, used how and where would lead to improved decision-making? (And how do you know?)
Often it does not require a new IT system. Sometimes it requires the creation of local systems for measurement and decision-making. These solutions are always much cheaper and more effective.
