Learning Objectives
By the end of this lesson you will have developed a knowledge and understanding of:
how to identify input, process, output and feedback in the production of a graphic product
how to draw up a logical order of work and know how this changes as the scale of production increases
AQA GCSE Design and Technology: graphic products

3. Input, process, output
Input is what goes into a system: the raw materials.
Process is the change needed to bring about the output.
Output is what comes out of the system: the finished product.

4. Feedback
Feedback is a way of changing the input or process as a result of what happens at the output.
In a shower system, feedback is a human response to the output from the water taps; if the water is too hot, the user will reduce the heat by turning up the cold.

1. Downloading an song on iTunes
2. Recording a TV programme
3. Sending a text
Ensure your system has feedback

7. Logical order of work can change as the scale of production increases
Storage of raw materials, bought-in components, sub-assemblies and part-finished products.
Inspection of bought-in parts or components to ensure that they are of the required quality; inspection of part-finished artwork of products to ensure that they meet design specifications. Inspection has to be done at all of the crucial points in the production process.
Operation is the processes of manufacturing.
Movement of raw materials, part-finished products and complete products.
