1 Project Control in the bar chart below the lighter bars in

1. Project Control: in the bar chart below, the lighter bars indicate the actually time spent on each activity and the darker bars show planned durations. Activity C is still not finished. Assume that one day of work costs $1,000 per activity. Use the earned value method and the 20/80 rule to compute the cost performance index (CP activities and for the project. I) for the TTtime lcurrent date

Solution

Earned value=value of A+value of B+completed part value of C

=4days*1000$+4days*1000$+1day*1000

=9000$

Actual cost=cost of A+ cost of B+cost of C

=6days*1000$+4days*1000$+1day*1000

=11000$

Cpi=ev/ac=9000/11000=.82
