A productive and high-performing team will inevitably have good communication, high levels of trust, and a positive approach to difference and disputes.
A manager intent on creating a team which goes the extra mile and is engaged and stable, needs to use dialogue rather than hierarchical grade, to motivate and manage the team. Because dialogue, done well, results in solid mutual understanding and commitment, rather than compliance.
Being able to have robust, honest and focussed conversations enables issues to be resolved or agreed directly and quickly; and means better decisions arrived at through consensus, which results in stronger buy-in.
This paper outlines how to use interpersonal skills to create a high-performing team.
