The principles for CT analysis need to be applied to a process with the flowchart shown in Figure 1 to calculate the CT. The process consists of nine activities. A decision point is included after activity C because an average of 20% of the jobs are required to go through activities B and C. This loop assumes that the reworked jobs are examined a second time and that they always pass the inspection. The process has three parallel activities, F, E and G. After the parallel activities there is another decision point in which an average of 10% of the jobs sent directly to the last activity I, the rest need to go through H activity before they end up in
