I agree with everything you say! Nice reference to that blue O/S, btwPut this into perspective. I have this on (extremely) good authority.
Barclays run every single line of their business critical code on z/OS (ie the back-end legacy systems). Anything that is not on z/OS is not critical to the business... I seem to recall at the same time being told that 80% of all business critical software in the world is run on z/OS...
So from this we can conclude:
Draw whatever conclusions you like.
- the important stuff is on the legacy hardware
- old legacy hardware is not an inhibitor to good practices
- badly installed software is the customer's fault.
Fact is the end user doesn't or should't really care what the front end looks like, all they bother about is the time it takes to fill in the forms and update customers info.
