It's difficult to determine why some government departments seem to have such a hard time coming up with reasonable cost estimates.
Most of the time they're experts in their own area and they should have access to data more easily than we do in our office. They have the expertise. They have the means to get access to data that sometimes we don't, so maybe it's a question of interest or a question of willingness to develop these cost estimates. Maybe these public servants who are asked to do these cost estimates—I don't know—don't have the desire to have substantial or credible cost estimates.
To be honest, it bedazzles me.
