When we looked at the total time savings, there were a few products and operations that stood out in particular. The most savings occurred when variance in functional and integration testing was decreased.
On SMA line it became apparent, that there is some excess capacity hidden into cycle times. In general, the planned cycle times per component exceed the actual median cycle times.
When looking at worker efficiencies, it became apparent that there exists a small subgroup of efficient workers, who operate at low time bookings and whose work times are very stable (i.e. no high outliers). Those workers should be used as trainers, and their work practices should be recorded.
Benchmark operator time for manual assembly phase at approximately 2.5 seconds per component.
Look into sources of variance in operator work, booking times in pre-handling and final assembly phases.
Implement adjusted cycle times for FCT. The time required to complete this step is sometimes overestimated.
Examine variances in ICT cycles. Lack of data makes it impossible to explain high medians and variances.
SMA cycle times are accurate, and current planning figures tend to overestimate the line’s full capacity.
