Executive SummaryWestover Electrical, Inc., is a medium-size Houston manufacturer of wire windings used in making electric motors. Winding or "Coil" copper wires wound around a core, to use to create or receive electromagnetic energy.
The company VP of operations Joe Wilson, has experienced an increasing problem with rejected products found in the manufacturing operations. Joe hired a consultant, Roger Gagnon to find out why the problems occur. left47688500Using different tools for Total Quality Management, it was determined that - Abraded wire, Failed Electrical Test and Broken Leads.
We gave three recommendations. The first one is hiring extra labor to accommodate the additional rework that will be done before sending it to Packaging. The second is to replace Machine/Winder 3 entirely since it generates the most defects among all the machines. The third option is for Machines 1, 2 and 3 undergo punitive maintenance since all the defects have been accounted for, for each machine.
The best recommendation is the 1st one. The defects were mainly concentrated in the machines 1 and 3 so the problems were mainly caused by this 2 machines and remedying them would lessen the defects that production will generate.
Problem StatementThe root cause of the increasing rejected products needs to be found to prevent further losses.

AnalysisBy using different quality management tools, we would be
