In many German companies, an employee with a better way of working can submit it to the betriebliches Vorschlagswesen, the company suggestion scheme. Experts assess the idea, and a committee decides on it and on the bonus. The works council has a legal right of co-determination over the principles of the scheme, under § 87 of the Works Constitution Act. A study for the Hans Böckler Foundation dates the first such scheme to 1871, at the Krupp company.
