Explain System design process with suitable diagram.
Answers
When planning a project a ‘systems’ diagram is essential. This will allow you to show your thinking regarding your idea(s) and whether or not they will answer the design problem. It also allows you to think systematically and logically about the design problem and how it can be solved. Above all, it keeps you ‘on track’ and does not allow you to wander too far away from the original design problem. A systems diagram is similar to a flow chart although on first sight it is much simpler and more precise. The diagram is usually part of either, the ideas or development sections. However, do not restrict yourself to these two areas, if you feel it is necessary, use this type of diagram wherever you like in the design process.
A simple systems diagram is seen below. This describes making a cup of tea, from the filling an electric kettle, brewing the tea, to pouring the tea into a cup. Remember, almost every process can be divided into INPUT, PROCESS and OUTPUT. When learning about systems diagrams and how they can be used, it is a good idea to practice drawing them, by describing a simple process, such as making a cup of tea.
