1 Instructions review the Scenario – Cisco Metals On January 3, 2018, following the Christmas production shutdown, there was a 2 day delay in the start-up of a production line at Cisco Metals. Over the Christmas shutdown, there was repair work happening on the furnaces in the facility. Thirty coils were being replaced in one of the furnaces. The delay cost 2 days of production at about $7000 per day. There were also 14 additional people on each crew working around the clock because of the maintenance delay. This delay was due to the maintenance staff not having the grinding wheels needed to cut this particular coil from the furnace. The grinding wheels they had were #62 and they needed #62-2. Maintenance had put in a request 4 weeks ago and received the wheels a week later, but did not realize they had the incorrect grinding wheels until the job was started. The purchasing department substituted #62 wheels for the #62-2 wheels that were originally requested. They appeared to be the same wheel and the #62 wheels were $40 less than the #62-2 grinding wheels. Purchasing regularly substitutes a less expensive part if it provides the same function. In this case, the material was different between the two grinding wheels and had been selected specifically for cutting the alloy that had been used in the furnace coils. The #62 wheels cut much slower and kept breaking which was dangerous though no one had been injured. The delay came from the slow cutting time, work stoppage, and waiting for the original #62-2 wheels that were now being sent on an emergency basis. 2) Create a Cause-and-Effect Relationship Chart Start small using a basic linear flow. Then use questions to fill in the details by adding causes horizontally and vertically to reflect additional information and/or "necessary and sufficient logic". Should contain, must have/follow these The causes identified are sufficient to produce the associated effect The causes identified in the map are necessary to produce the linked effects Impacted goal is properly identified Enough detail is provided in the map that the final causes are solved, they will prevent the issue. Evidence of causes is provided where possible. Leadership, ideas, and collaboration shown in MSTeams and/or participation in at least one meeting with group provide me with whats needs to be filled into the cause , effect, event , and other boxes of the cuase and effect (fish bone ) diagram i'm making now a day ago Good response
