Now, if a hi vis vest costs £5...
except that only reflects the purchase price, there's the initial trial, the procurement documentation, the lawyers needed to create the contract, plus the distribution system, replacement strategies need to be created, adequate stocks need to be ordered and issued, with a sufficient reserve kept on hand, then they need to do a study to see if the vest meets the expected level of service: how long does it last? do the buttons fall off? do we stock more buttons or simply replace the unit in toto? are defective ones returned to the vendor or scrapped? Is it even the correct colour of orange? ... or shold they be a billious light green?
Then there has to be a team to measure the effectiveness, was any life actually saved? was any life lost despite the vest? how do we know? What logging system needs to be in place to verify the cost effectiveness and what are the review parameters for this? Wjo gets the figures reported to them and what do they do with them? How long do they store them?
Then there's the actual time required to don and doff 50,000 units go on before breakfast and come off at night every day, even if it only takes 1.2 seconds that's erm... 60,000 seconds a day, which is 1000 minutes which is about two man days. How does that get paid for? or tracked?
