"Kong Hee Fat Choy" and welcome to the Year of the Ox! As you will have known, last week marked the Lunar New Year, and I expect that the virtues we associate with the ox - such as strength, persistence and determination - will be very apt for the year ahead.
Among other cultural preferences that westerners have become familiar with in the last few years, we all know the value that the Chinese place on the number eight (how many millions of dollars changed hands for that single-digit number plate in Hong Kong?).
Well, sorry to rain on that parade, but last year some interesting research, entitled 'Parkinson's Law Quantified', established that eight is the worst possible number of members for an effective decision-making governance body: most of the research centred on the number of cabinet members in nearly 200 governments, but the researchers apply the findings equally to Boards of directors.
The first finding, which will surprise nobody, is that "cabinets or Boards become highly inefficient once
their size exceeds a critical 'Coefficient of Inefficiency', typically around 20." (Do you realise they actually fund people to research the blindingly obvious??)
The second observation is a re-statement of the widely-acknowledged 'Parkinson's Law', namely that "the growth of a bureaucratic or administrative body usually goes hand in hand with a drastic decrease of its overall efficiency." Well, yes, I do live in Wellington so this isn't actually news either.
As one outcome of their research, though, they found that a Board (or cabinet) of eight members was the most likely to lead to deadlock and internal conflict. I'll let you work your own way through the complex maths that the authors use to explain their findings, but I think that here they may have missed one crucial point - particularly as it relates to an effective Board of directors. This is that an effective Board will operate largely by consensus decison-making, rather than on a simple majority. In other words, most effective Boards will be unanimous in most of their decisions. I don't see any loss of effectiveness in having one or two dissenters, as long as it's not the same one or two people with every decision; but if you get to the point where a Board is split down the middle, then usually some more fundamental questions - like agreement on direction and strategy - need to be sorted out first.
It's for this reason that I have never been concerned about a Board having an odd or even number of members. In fact, in over 16 years and a large number of Boards, I can't think of one decision where having an even number of Board members became an issue for us. An effective Chair will usually pre-empt any difficulties, understanding in advance what most people's views are likely to be (without pre-judging the outcome), and will generally not allow an issue to go to a vote if it is likely to become divisive.
On balance, despite the mathematical 'proof', I have been happy serving on Boards of eight members. My preference usually is for fewer rather than more (I like Boards of 5-7). However, sometimes you need a reasonable size - very seldom more than 10-12 - to cover the full range of perspectives, experience and competencies that a Board might need.
As a footnote to the paper, the researchers uncovered only one cabinet of eight members, King Charles I's "Committee of State". And, as they note, "Look what happened to him!" Based on that sample size of one, therefore, who are we to argue?
