This case study is about the productivity improvement in a small scale Indian automobile industry. Industry produces the parts of light commercial vehicle for a multi-national company. Industry is unable to produce a nut steering knuckle component used in light commercial vehicle at economic rate due to a problem of higher rejection rate having average 15.18% defective pieces per month. Study is carried out by applying the fishbone method of root cause analysis on planning and manufacturing processes of nut steering knuckle component. Findings of this study show that fixture is also a factor of its production incapability. Modified fixture and implemented and a satisfactory result is obtained. When production after applying suggested modifications is run, a 0.78% reduction is observed in rejection rate of that particular component.
