Inside the "black box": the performance of boards of directors of unlisted companies

Purpose - The purpose of this paper is to explore two under-developed areas of board research: the corporate governance of unlisted companies; and board behaviour, focusing on process factors that contribute to a board performing effectively.Design methodology approach - The Board Effectiveness Questionnaire was completed by 67 directors, to gather views on how their board currently operates and how they think it should operate, across various behavioural areas relating to the relationships, decision making, the working climate and predispositions. Analysis of "process losses", the pattern of sub-optimal board behaviour, allowed the testing of four hypotheses concerning board effectiveness.Findings - The 18 most important and five least important behaviours were identified, plus 12 showing the greatest "process loss". Quality of team "relationships" is the main cause of loss whereas evidence for the impact of leadership style is mixed. Size of the board is related to overall performance of the board but number and proportion of non-executive directors are not.Research limitations implications - This is a "purposive, judgmental" sample of all unlisted companies, derived from those who were willing and able to respond. Only one director's view of each board was sought.Practical implications - The picture of the "ideal" board provides a checklist for a company wishing to assess its board's performance as a working group, highlighting key characteristics that should be reflected on when discussing director board performance. The gaps in board behaviour identified could help other boards assess their own performance and researchers to focus on these areas.Originality value - The paper explores two under-researched areas.
