A recent meta-analysis confirmed there is a positive relationship between how much team members trust one another and the achievement of team goals. What’s more, it seems trust between team members is related to team performance even when you take into account other factors, such as trust in a team leader and past team performance. Trust seems to matter most for teams that concentrate decision-making responsibility amongst a small group and least for teams where individuals can work relatively independently to complete their work.
