Measuring Efficiency

Hi All,
I am a team manager and I need to calculate the efficiency of a team. Your help would be greatly appreciated. Please see the parameters below:
There are 40 employees in a team and they perform 5 different activities and to complete each activity it takes a different amount of time. For example,
Activity A - 4 min
Activity B - 5 min
Activity C - 3 min
Activity D - 10 min
Activity E - 6 min
The employees need not perform all the activities on the same day. Let's say,
Employee 1 - perform activity A and C today whereas,
Employee 2 - performs only B and D today.
The next day the activities are interchanged between the employees. By the end of the month I have a report that consists of numbers but I am not able to really find out who is more productive and efficient in performing a task.
I would be very happy if someone could help me in calculating the efficiency of each individual.

Hello,
You have not given sufficient information to guide you. Are these activities related? Can you also include a flow chat if these activities are related? If you have data for all the staff on a spread sheet can you attach it.
I have worked as a Productivity Services manager in the past and can answer your query; please send me a private message with all the details. I will give you my e-mail ID to send the attachments; if you do not want to publicise it at CiteHr.
Have a nice day.
