10 top strategies on improving work efficiency | TonyRobbins

When you improve efficiency, you're able to get a larger output from the same amount of input – or even less. For employees, this means being able to get more done in a finite amount of time: the workday. You can calculate work efficiency with this formula: output / input = efficiency. The output in the formula is the standard labor hours.
