Quality Improvement Methods
54. Visual Controls
c. Definition: Often communications can be more simply and clearly communicated with a visual message, like a traffic light, than with words or numbers. Toyota found visual controls or messages to be a very effective and efficient way to communicate operational messages and they visual controls are applicable in healthcare as well. Visual displays are a way to keep both staff and patients informed and to provide direction for necessary actions. The recommendations resulting from QI research may require a change to current practices and visual controls can alert staff to the changes as well as reinforcing the recommended practice.
d. Literature: Most books on the Lean Method also describe visual control ideas.
