Board and executive sponsorship

Our Board are aware of us doing this, our innovation subcommittee is very aware of it. So there's going to be no restrictions there. All the exec are absolutely on board. SITE LEAD

Seniority of economists

We were thinking anyone in the team could have been the economist that's going into these organisations. But the more we've got into it and the more we've understood from the sites potentially what it is that we could be doing, the more it became important that the outward-facing economist needs to have a particular set of skills. I think it's a combination of the soft skills around the relationship stuff, and being able to listen to somebody, extract a brief, and being able to apply, then the economics background that we have and bringing that critical reasoning to that other person's problem. eE 2
