Throughout the ages people have sought to understand the world around them and to explain it in a systematic way. A system is simply a group of elements which work together to achieve a purpose.

Systems can be very large, such as the system of courts and laws we call our ‘legal system’, or very small, such as the system involved in cleaning your teeth. Systems can occur in nature or be designed by people. The water cycle (described below) is an example of a natural system. Banking systems and computer systems are examples of systems designed by people.

Processing systems accomplish a task: they take one or more inputs and carry out a process to produce one or more outputs. An input is something put into the system, a process is a series of’ actions or changes carried out by the system, while an output is something taken from the system.

All systems can be represented by the following input-process-output (IPO) diagram.

The shaded area in the diagram represents the system. The letter ‘I’ stands for input and the letter ‘0’ stands for output. The input into this system is an output from another system and the output from this system is an input into another system.

To develop these ideas further we will consider three systems: coffee making the water
cycle and the shop.
