Give examples of visual control. How does visual control affect quality? What is a poka-yoke? Give an example.

Solution

Visual control means using visual signals on the place of text to easy recognition and quick communication. The benefit is that is takes very less time to understand what is the order hence it increases the efficiency and clarity. Audible signals can also be used it comes under visual controls.

For a general example if there is a red dot on the DVR it means recording is going on. Traffic lights to control traffics etc.

In organization the examples are like foot prints are printed on the floor tiles to make the customer understand the way for reception.

In bank different sign board are hanged in easy recognition where money can de deposited, where ATM query can be resolved, where you can approach for loan etc.

As far as quality is concern, let us suppose a customer went into the bank and he has any ATM issue, now in Bank he will ask different people or counters that where his problem can be solved where he should go. Now if the visual signals are there he can easily find out where he has to go. Now suppose there are 100 customers in the bank and there is no any visual signals they what be the scenario of the bank. This is why signals are used. And this way the efficiency and quality of the bank is creased.

In a production line there may be lights working s a visual signals showing the condition of the machine. You can easily judge whether they are working or not without any hassle. Suppose light is indication that the machine has some error then you can easily find out and resolve the issue before starting the production.

Poka-Yoke is a Japanese term which means ‘mistake Proofing’. It is used in lean manufacturing. By using the visual signals mistakes clearly stand out from the rest. It is a device that prevents any defect and informs about the defects a well. By this the next process is not started until and unless the error is rectified.
