Mechanical Technical Risk Assessment Current High Level Risks P08310 – POLARIS OUTLAW 525 DESIGN TEAM Mechanical Technical Risk Assessment Current High Level Risks Weight specification of less than 7 lbs of additional weight. Pneumatic system failure based on contaminants and foreign materials. Air line failure due to debris from riding in rough terrain. Proposed Mitigations Design the attachment piece and covers with a lightweight material (Aluminum). Design covers to protect the critical components (cylinder & valves). Use reinforced tubing and design it to be not in direct view of debris being thrown from the tires.

State of Design Summary P08310 – POLARIS OUTLAW 525 DESIGN TEAM State of Design Summary Design meets all customer needs Engineering specifications are met except for: Weight limitation of 7 lbs. (Currently at 5.5lbs. + weight of fittings, brackets, and cover) Budget criteria is based on 500 pieces (initial cost of goods based on 1 piece order). Specified Build Cost (ea.) = $250 / 500 orders Current Development Cost (ea.) = $436 / 1 order Mitigations: Weight will be controlled by designing covers to size & by using lightweight material. Quotes are out to the appropriate suppliers based on a 500 piece order. Alternative parts may need to be specified (Once quotes are returned)
