My first point is that if, for once, an IT director has NOT lapsed into impenetrable jargon and just used an 'ordinary word', the least we can do is translate what he says :-)

Second, I confess I immediately understood "tout comme" rather than "comme par exemple", this is backed up by what "retours en arrière" means, which is basically "regression" (that bit IS jargon! - it means reverting to a previous situation, often in a context of backing out an upgrade which has proved to be defective in some way, but used its more general sense here).

"évolutif" is, of course, usually translated as "scalable", quite rightly, but let us not forget than both terms do not necessarily mean bigger and better, but merely "different from before", which includes the possibility of being smaller, providing less, not more, functionality if that is the requirement.

All of which means that the head of IT said:
"... a scalable information system where both new openings/options and (indeed) regression are possible/possibilities".
