The work of innovation teams that help reduce lost production time and make production more efficient on Boeing's 737 production lines in Renton, Washington. There are 1300 improvement teams at Boeing for commerical jet production. Examples range from conventional improvements such as remapping production arrangements to unconventional ones like the use of hay loaders to put seats on passenger planes. The work requires highly motivated production engineers and Boeing has a long tradition of this. Boeing has increased 737 jet production to 35 a month from 31.5 with the help of such improvements. The goal is to make 42 planes a month by 2014, and 60 by 2017 when the 737 MAX goes into production. Boeing has a large backlog of orders- 3,700 jets of which 2,300 are 737s.
