Visual control is a business management technique employed in many places where information is communicated by using visual signals instead of texts or other written instructions. The design is deliberate in allowing quick recognition of the information being communicated, in order to increase efficiency and clarity.
3. VISUAL CONTROL
Introduction
Basic Philosophy
1. Visual elements in a workplace have a tremendous impact on
education, morale, and productivity.
2. A visually dynamic workplace energizes employees, builds
pride and ownership, and conveys the strength and currency of
the organization.
3. Design and graphics, art and color, sculpture and dimension–
all have profound effects.
4. Far from simply “prettying up the office,” they create an
environment of visual stimuli that convey goals and
expectations, that foster a collaborative attitude, and most
important, that cannot be ignored!

Introduction
What is Visual control ?
“ One picture is worth a thousand words ”
Visual control are means, devices, or mechanisms that were designed to manage
or control our operations (processes) so as to meet the following purposes:
1. Make the problems, abnormalities, or deviation from standards visible to
everyone and thus corrective action can be taken immediately
(Identification).
2. Display the operating or progress status in a easy to see format
(Informative).
3. Provide instruction (Instructional).
4. Helps formulate and proliferate plans (Planning).
Thus all visual control devices can be classified as one of „3I1P’. (Three I‟s and 1
p)

Examples of visual controls:
What is Andon ?
• Jidoka or „Automation with Touch‟ is implemented in
the Toyota Production System.
• Machines automatically stop production as soon as an
error is detected.

VISUAL CONTROL
Examples of visual controls:
What is Andon ?
• As machines had the
capability to automatically
stop production a single
operator may visually monitor
multiple machines.
• Toyota plants pioneered the
use of a display board system
to highlight a problem on the
line; this is an Andon board.
