CRITICAL RATIO
1. Calculate the critical ratios for the following activities and indicate which activities are probably on target and which need to be investigated. Comment on each activity.
Activity Actual Scheduled Budgeted Actual
Progress Progress Cost Cost
A 4 days 4 days $60 $40
B 3 days 2 days $50 $50
C 2 days 3 days $30 $20
D 1 Day 1 day $20 $30
E 2 days 4 days $25 $25
2. Given the following information about a showroom renovation, which activities are on time, which are early, and which are behind schedule?
Activity Budgeted cost Actual Cost Critical Ratio
A $60 $40 1.0
B $25 $50 0.5
C $45 $30 1.5
D $20 $20 1.5
E $50 $50 0.67
3. Design and plot a critical ratio for a computer installation project that had planned constant, linear progress from 0 to an earned value of 200 over a 100 day duration. In fact progress for the first 20 days has been: 2, 3, 4, 6, 7, 9,12, 14, 15, 17, 20, 21,21, 22, 24, 26, 27, 29, 31, 33. What can you conclude about this project
