Attempting to change IT estate 'usually doesn't work'

Attempting to change IT estate usually doesn’t work, director of consulting and professional services Ray Blackman has said.

"If you look at transformational change, somewhere in the region of 80 per cent of those initiatives fail to deliver the benefits expected by the sponsors," he explained.

Companies expect better customer service, risk reduction or cost cutting to come out of attempting to change IT estate, Mr Blackman claimed - and some in leadership development might feel the same way. 

But around 80 per cent of these aims won’t come to fruition or prove to be a fruitful investment.

"Now we can argue many, many reasons, but the fundamental underlying reason is if you haven't got control of your as-is world, how can you expect to be successful?" he asked.

He said companies were altering parts of a whole, but lacked understanding of how they work together.

"The reality is if you don't know what all the interdependencies are and where everything points in your infrastructure and you try and change it, it's certainly going to go wrong," he said.

"If you try and change any or all of [an IT estate] for whatever reason and you haven't got your pieces of the jigsaw together, you are much more likely to make mistakes," the expert has explained in the past.
