Each will have to do iterative process development listed earlier: –catalyst suppliers –muffler suppliers –tank suppliers –resin and additive suppliers, or other material suppliers –barrier treaters –canister suppliers –hose suppliers –connector suppliers Each vendor has to deal similarly with their vendors/suppliers Additionally, engine manufacturers and OEMs will be evaluating and selecting candidate(s) from each of these supplier categories
