People need to transition from 100% code* to 80-90% code and 10-20% do things that are good for the company and team's productivity (using that word in the broadest sense). You want all hands to spot the cracks and fix them. You probably want to create a culture where people do that.

*code = code, design, discuss code, write tickets, test etc. i.e. get the shit done on the plan

You may need to transition to making willingness and ability to do that (i.e. be an owner) a hiring criteria and performance criteria.
