Hi there,
When you ask what is the progression in IT - i would be asking...
What do you wan to progress in?
Unlike Business where it break down to Marketing, Accounting and etc

In IT
It is still a very wide scope
What do you want to be?
Programming, Security, IT analyst, Project Management, Database, Web dev, Sys Admin and many more..

Maybe you should be asking - what area do you wish to focus into - before asking that question...
