How to increase productivity

[Deanc31]

Come back to the game after having some time off and its changed a bit and I'm trying to remember how to play again...

Doing the Swedish run through and trying to figure out how to do the productivity part of the tutorial, how do I get it to increase? (in basic easy terms for me to understand)

Switch to better production method

[Blaarg]

To increase the productivity of a specific building you can:

Reduce the cost of the input goods by increasing the supply of them
Raise the cost of the output goods by increasing the demand for them
Change the production method
Increasing throughput (with a company or a decree) can improve productivity, as long as the benefit from more effective use of wages overwhelms the resulting change in price of the input/output goods
