1. Commercial Production Methods:
One-off (Job) production; understand that this involves producing ‘one off’ products. Every item produced is different. It is labour intensive.
Batch Production involves the production of a specified quantity of a product. Batches can be repeated as many times as required. This type of production method is flexible and can be used to produce batches of similar products with only a small change to the tooling. e.g. using templates and jigs.
High Volume Production involves producing large numbers of identical products for a relatively low cost. The production is usually broken down into sub assemblies of smaller components. This form of mass production has a low labour cost or completely automated.
Can include Continuous Flow production which involves uninterrupted 24 hrs/day production of products that are always in demand. This type of production continues because it is expensive to shut down and then re-start. Only a small workforce is needed to maintain the process.

2. Batch Production Techniques:
Templates; a tool that is used to mark out accurately every time
Jigs; a tool that is used to cut or drill in the correct place every time
Formers; A tool that material can be shaped around to make it the same shape every time
