Are you sure you've got the name right there, Andy (I've never heard of these people)?
It's not a name that I would chosen, by the way. After all, it hardly conjures up a notion of open ("transparency") and unbiased attitudes, does it (to my mind at least)? Perhaps theirs is a five-pronged attack ... er, approach?
And, what is the "optimisation" of medical equipment all about? If it means what I guess it means, that is going through the inventory and identifying any surpluses (or, more likely, old, unreliable or redundant equipment ripe for the cull), why does any Trust or Health Authority need to bring in external people in order to do that?
Is the idea to make (further)
savings ... or what?
I wonder do they also recommend
adding to the inventory as well? And, if so, which suppliers and/or manufacturers do they favour?

For what it's worth, what I would advocate is a review of the equipment inventory, set against current "norms" in terms of quantities and distribution (placement ... where the kit is). Recommendations should be made where deficiencies are apparent. And then an inspection of
all the kit to ascertain its condition, thereby identifying what needs to be repaired or scrapped. Simplification, rationalization, good equipment husbandry. Is that what these people are talking about?
