1. Productivity is defined as Output/Input. In this context, productivity increases when:

1. the same output is obtained by using less inputs (resources), or
2. more output is obtained by the same inputs, or,
3. the increase in output is more than the increase in inputs, or,
4. the decrease in inputs is more than the decrease in output.

By taking into account the service businesses that you are familiar with, (eg, banks, doctors, airports, supermarkets, cafes, restaurants, transportation firms, shopping malls, supermarkets, any kind of shops, etc.) give 5 examples for improvements that are aimed to increase productivity in such service firms.

I will definitely give like if you solve it :) Thanks
