23 Feedback
Introduce feedback (referring back, cross-checking) to improve a process or action.
• Automatic volume control in audio circuits
• Signal from gyrocompass is used to control simple aircraft autopilots.
• Statistical Process Control (SPC) -- Measurements are used to decide when to modify a process. (Not all feedback systems are automated!)
• Budgets --Measurements are used to decide when to modify a process.
If feedback is already used, change its magnitude or influence.
• Change sensitivity of an autopilot when within 5 miles of an airport.
• Change sensitivity of a thermostat when cooling vs. heating, since it uses energy less efficiently when cooling.
• Change a management measure from budget variance to customer satisfaction.

The colour indicates the ranking of the proposed principle to solve the contradiction:
1st,
2nd,
3rd,
4th.
This ranking reflects the frequency of occurrence of the principle in the analysed patents for this type of contradiction.
When a principle appears in first position, it means that it is statistically the most used in the patents studied for this type of problem.
