In the world of mieruka, or visual control, instructional controls help to show people what to do, or don't do. Here are a few examples straight from Toyota's facilities.

Clearly marked areas
This area is clearly marked for delivery, making sure nothing is mixed up.
The floor too is clearly marked to ensure that there is order when placing pallets orboxes, helping to put everything in order.
Each shelf is marked with identification tags, both machine and human readable.
These lines and signs help to ensure that everything is kept neat and in order, making it easy to find something, saving time and increasing efficiency.
Each location is also clearly marked so it is easy to find.
Again, "NG" goods are allocated a space as well as the red colour, so that people will place defective goods here.
In this example, unprogrammed ROM chips, defective chips and successfully programmed ROM chips are clearly segregated through clear markings on the table. There will be little chance that they will be mixed up, providing the quality and attention to detail that Toyota is legendary for.
The above example is the same, there "NG" stands for "No Good" - naturally faulty LCD units are placed here to be returned to the supplier.
Tools are clearly placed and within easy reach to reduce the necessary motions to perform a function.
Labels with colour coding
Each product is clearly labelled, and on each label is a colour code to make identification easy and instant. This chart provides the identification colours and what they represent.
Careful! Static Electricity!
As this Toyota facility also deals with highly electronic components which are highly sensitive to static electricity, a large sign reminds people to ground themselves prior to touching these components.
This piece of equipment is to test whether LCD displays are faulty or not. The testing steps, as well as ways to identify whether the LCD is bad, are clearly displayed right in front of the testing machine. It leaves no room for doubt or error.
Designed to show the visitor on the process and that it is organised, each process to program a ROM chip is illustrated by a series of wall charts.

Each of these examples have been well thought out before being used. Each line, each colour and even pattern all have a meaning. When you make your own visuals, think it through carefully to maximise the instructional value of your visual control.
