1. Capacity = Theoretical maximum number of units can be produced in the line
2. Labor Productivity = Units produced per employee per hour (also know as man-hour)
3. Capital Productivity = Revenue produced per dollar invested in the line.
4. Combined Productivity = Revenue produced per combination of dollar invested and labor employed. This is governed by theories like Cobb-Douglas Function.
5. Utilisation = Actual units produced divided by theoretical maximum possible (capacity)
6. Efficiency = Total man-hours of effort spent divided by the theoretical man-hours required based on an ideal labor productivity level

Productivity is how much output there is per input unit.
Efficiency is the percentage of the actual output to the expected output (if everything was working well).
 

Hi!

I think you're actually on the right track and I agree with your definitions.

Best,
