Accountability becomes a collective behaviour of the team. When a team member does not commit to a clear plan of action, the peers hesitate to call on the actions which becomes counterproductive for the entire team. This behaviour pulls down the overall team’s productivity and performance rather than being a self disciplined team.
Team members should challenge difficult issues to hold each other accountable. Clear protocols defined on team behaviour by the team themselves, regular introspection, appreciations would ensure the team stays healthy and accountable for their actions.
