All three types of controlдЫУfeedforward, concurrent, and feedbackдЫУare used at Lincoln Electric. In terms of the feedforward control, employees demonstrate this through self-control. Concurrent control is conducted through regular inspections of the production process. Finally, feedback control is displayed through company reviews, annual bonuses, and the financial statistics. Lincoln Electric largely adopts a decentralized system. This is because the relationship between employees and management is based on trust more than authority. Also, this is shown by allowing employees to challenge management if they feel that something is not right.
