1. A method of analyzing production cycle queue time to optimize process steps, the method comprising using a computer in: selecting a plurality of process steps for a production cycle; calculating queue times for each of the plurality of process steps in a semiconductor fabrication process operation; statistically analyzing the queue times to determine a correlation between queue times and at least one of process yield and quality; generating at least one visual output illustrating the statistically analyzed queue times; and adjusting a parameter of the process steps to reduce the queue times.
