In order to ensure that the roles and responsibilities of the Board of Directors are effectively performed, it is recommended that the organization should conduct board evaluation on a regular basis. There are various evaluation approaches and each board should apply a process that best meets its needs. Beyond the traditional use of questionnaires (self and peer rating techniques), organizations may develop metrics for performance (inputs and outcomes) or commission an independent review that includes detailed interviews of directors and senior management. In addition, it is now common practice to evaluate the performance of individual board members. It is also useful to consider whether those sitting on the board have the skills and expertise appropriate to the organisation.
