If a job done in 2 hrs can be completed in 1 hr with improvements what is the percentage of improvement?

Answer 1

50%. You´ve cut the time in half.

Answer 2

50%. Some other people may consider it as breaking down conditions. If you can do the job in one hour, but are given two, then this will help give you a break and you can take it a little easier to help you get through the rest of the day. You may also be given a job that takes 3 hrs and you are given 2. So that extra hour you have saved will come in to play.

A lot of it depends on whether you are hourly or salaried.
