Collaboration has always been one of those factors that drive a team’s performance. How quickly can a target be achieved when people are clear of what their colleagues are doing and also about their contribution to achieve the target? And they can now be clear about who they will have to approach to get their queries cleared or just ask the query and have it answered by any of their colleagues.
