Common problems facing teams are communication, trust and leadership skills. In my opinion most of the common problems within teams, are very easily recognisable and are easily dealt with in the short term. For example, poor communication skills or a lack of communication skills, and a lack of understanding or appreciation of each team member.
Good communication does not mean being able to stand on stage and just tell people a message; good communication means being able to share a message which is heard, received, understood and appreciated. Communication is a two way street.
What defines a good leader? In the leader’s opinion, it might be to be strong, be directive, be controlling, be confident. But what does the team require? They may require very little from their leader, i.e. give them instructions and then leave them to do their work, or they may require a lot of direction. It is up to the leader to decide which approach to take and which one will best suit the projects requirements
