Productivity depending on different type of work

Hey,

This may be a strange question but I need to know if the below is possible and if it is I may need some help with it

So I need to figure out how productive a group of people have been per day.I know how long they've actually had working (excluding breaks etc) so lets say out of 7 hours they were only working for 6 hours, I would need to do this every day so the hours would keep adding up along with how much work they completed so at the end of the month we know their figures.

The confusing part for me is that each type of work has a different target so Work Type 1 has a target of 4:40 hours and Work Type 2 has a target of 2:20 hours etc.

I need to see if it is possible to work out the productivity based on these and if its possible I need to try and get my head around it.

I've attached a little sample that I put together so any help would be appreciated
