Ever designed a computer system which has gone live?

Strange question I know

I've designed quite a few computer systems, and associated business change, that have gone live successfully, some small, some huge, some simple, some complex, some Greenfield, some changing an existing IT estate, many challenges sure but a track record of live systems out there

It's surprising how many folk who call themselves architects in the IT business have never done this

Many "Architecture practise" heads or leads have never done this, many so-called leaders in the profession have never done it, and boy does it show

We have a high failure rate in our business, and yet it's easy to survive and even prosper with little idea of the challenges of real projects
