Whilst we will never know what happened, you can be sure that responsible staff in the IT department will have been warning about this for years. Whenever there is a massive corporate stuff up - the warnings were ignored. That's because
- The Board don't bother listening to staff
- The senior managers and Board have, mostly, come directly in from Uni or another company.
- The days of someone at the top actually KNOWING and UNDERSTANDING what is happening at the bottom are long gone.
- The outsourcing is a sympton of the problem - not the cause.
- Now that Board members can have a wireless router sent in the post and it's plug-n-play at home, they think that IT is easy. I wish I was joking but I saw that attitude over 20 years ago.
