Measuring productivity

How to measure actual work productivity? I would suggest to divide measuring productivity into more specific parts. E.g. productivity of planning something, productivity of doing something, productivity of analysis.

I think that it is hard to measure productivity of planning, but actually, good plan is the most important thing. Productivity of action is more measurable thing as there are results that can be measured.

The most interesting is measuring the productivity of some creative job, e.g. thinking about new idea or new product. How to measure productivity of this? The good start is measuring the number of ideas that first were ideas and now were released as a project or test project. It doesn’t matter if the project really shot, because one need to do a lot of mistakes before something will really work out.
