Every now and then, I come across a public sector client who wants to supplement their Essential criteria with a couple of Desirable ones. They put forward that if you include some of the nice-to-haves you might just get lucky and find someone with them. Plus, you’ll get to the end of the selection process, there’ll be two or three candidates that are good, and you’ll be able to pick the one that offers the most of the extras. Bonus! Good sensible thinking? Perhaps if you’re in the private sector that will work… Just between you and me – private sector don’t always even write down the essential criteria and have been known to create a job on the fly when they’ve chanced on a good operator. However, this isn’t valid thinking in the public sector.
