Imagine that you are about to make a critical senior appointment for your company. In fact an appointment that is widely regarded as the most crucial and high profile in the industry. Getting the right man (or woman) for the job is essential to your immediate future success. You consult your colleagues, you perhaps speak to some head hunters about who is out there. Then you interview only one candidate and immediately appoint him.
Could you do that ? I don’t think I could. Even if I knew exactly who I wanted for the job, and in our industry it is easy to think that you know or know of all the top people, you would want to bring in more than just one person to talk to. I also think I would want some people who were left of field to interview if only to endorse my decision.
