‘Strengths-based performance conversations’ aims to move managers away from a deficit-oriented method, which is focused on identifying and fixing the weaknesses of team members, analysing what has gone wrong and considering how that can be avoided in the future. The new study of performance management outcomes in the civil service shows that that employee performance can be improved by a simple training intervention focused on building strengths instead of fixing weaknesses. These results can be boosted by a more extensive intervention, which includes wider communication and changes to HR policy, as well as manager training.
