Streamlining engine assembly boosts output

Client Results Story

Opportunity

AutoCo is a major automotive manufacturer whose large vehicle group is extremely profitable, but customer demand for these vehicles exceeds existing capacity 

AutoCo's large-vehicle production is constrained by engine output. Executives want to increase the rate of engine production by five jobs per hour. 

Plant management determined that XYZ Assembly was the primary obstacle to achieving the engine production necessary for the target number of vehicles.

As part of a full potential manufacturing improvement program, AutoCo charged the Bain team with:
  • Improving productivity at the bottleneck machine on the main assembly line 
  • Improving the yield of the subassembly department feeding the bottleneck machine 
  • Finding five more engines per hour (JPH) on the XYZ Assembly and on the mainline station it feeds

Recommendations
The team focused on a 1.5 second-per-cycle overrun that occurred 75 percent of the time and yielded an 11 JPH loss.
