Productivity is a measure of output completed whithin a time frame. This could be goods, services, or even personal goals as long as the output is measurable in some way and it was completed within a realistic time frame.

Washing dishes, losing weight, and making children happy can all be counted as productive if there are goals and a way to measure them. Even reduced anxiety by taking s day off could be described as productive if there is a way to measure it even if the measure is subjective. Cleaning up a park can be productive even though the end result is removing things instead of creating them!

Basically it is getting things done within a reasonable time frame and is not limited to business.
