Triz Principle 10 # Preliminary action

When something is to be done at some time, Prior Action means preparing or taking some action beforehand to smooth and ease the event when it does occur. For example, laying the table for breakfast last thing in the evening will save time and stress on the following morning in the sleepy hurry to eat and get to work. It is far too easy to design a device or manufacturing process so that something is done when it is needed to be done.

Pre-arrange objects such that they can come into action from the most convenient place and without losing time for their delivery.

When we copy a file to a disk, it is possible that the target disk may not have enough space to accommodate the file. In such case the copy operation will proceed only half way and then crash because of insufficient space. Hence, most copying programs first checks the space in the target disk and confirms availability of sufficient space before starting a copy operation.

 

A. Perform, before it is needed, the required change of an object (either fully or partially).
