The importance of crossing the disciplines

When you're part of a "modern" software building team, changes are, it is being referred to as "multi disciplinary" or "cross functional". This is to indicate that the team is made up of backend developers, frontend developers, some design role(s) and maybe somebody in charge of metrics and KPIs or some additional, specialised roles.

The thought process here is that if you do that, the team can be completely in control of their responsibility (maybe add some DevOps terminology in there then, as well). Which makes for agile teams.
