One of the greatest problems of our accountability system generally is the short tenure of people in various positions--deputy ministers, ministers themselves, and frankly, members of committees, including this one. I've spoken particularly on that point.
I agree with Professor Franks. The obvious solution is to have established expectations of tenure of four- and five-year terms, and so on--with the provision, of course, that there be flexibility and a chance to move things; these are not necessarily fixed terms.
Right now there's no expectation of how long a deputy is going to serve. There's almost an assumption that he or she will be moved in two or three years. If we went to an expectation of normal four- or five-year terms, it would give much more predictability. Of course, that can be applied to other positions as well.
