Why is the junior non-productive team resistant to change? answer this and you might get an answer on the path forward. It sounds like this team wasn't responsible for this mess - but then they should be excited to try something better. On the other hand, if they think this is all great, then why is productivity poor? if this is all PHP code I'm not sure what the difference between front-end/backend would be - what is the mobile person doing on prod PHP code?
