what is a bottleneck in manufacturing 
a bottleneck occurs in manufacturing when there is a stage or stages in the process that slows down the overall production of a good for instance initial steps may rapidly assemble key parts but a crucial next step that welds the parts together may not be able to keep pace with the earlier stages as a result a backlog occurs and efficiency is reduced the bottleneck should be solved by expanding that process investing in better technology to speed up that process or hiring more workers to help with that process
