1. Cycle time analysis Company X has recently completed an ana copy formatting from one location and apply it to another lart of this analysis, the major flows have been mapped such that the process has been broken down into 10 sequential activities. To better understand the process, the times to complete each of these activities have been carefully monitored over the past month. The average (mean) and standard deviation of the activity times are recorded in parentheses next to the box representing the activity, as follows: (3:3) (1:0.4) (10:6) (5:2.8) Standard Activity 4 Activity 5 Activity 6 Activity 7 Activity Mean Deviation 1 8 2.4 2 4 Activity 3 (15:21 Activity 8 (3:3) 3 15 2.1 4 3 5 1 0.4 Activity 2 (4:12) Activity 9 (20:4.5) 6 10 6.0 7 5 2.8 8 3 3 Activity 1 (8:2.4) Activity 10 (4:0.3) 9 20 4.5 10 4 0.3 (Mean: Standard Deviation) 1.2 3.0 1.a 1.b 1.c 1.d What is the average completion time for this value-added process? What is the standard deviation for the entire process? What is the probability that process will be completed in 75 hours? in 80 hours? in 70 hours? Develop a 95 percent confidence interval for the process. If you aren't confident in your ability to make delivery promises, where should you target your improvement efforts?
