Moving is different from working. Our time is spent in doing various activities. Moving from one place to another consumes time. It can be a movement of the limb. Or it can be just the mind wandering! All these movements cost your valuable time.
If you ask an industrial engineer, he will tell you what is a value adding activity and what is a cost adding activity. Every movement should be a well considered and well planned move.
Wherever possible, use both of the hands. On the most occasions we use one hand only. Some of the Japanese management techniques stress the use of two hands.
Take a look at your work area. Does it make you do unnecessary movements such as bending, walking etc.? Consider how you can eliminate the same. Plan your work area in such a way that it is a ‘work station’. Decide where your filling cabinet and your side tray should be.
