Students are introduced to 4 different scales of production that they may come across, one-off, batch, mass and continuous through a video clip showing a wide range of products which they need to categorise into a type of production. Details are given on the characteristics of one-off production, and how it can be applied to engineered products. Students consider how they could describe one-off production and its advantages and disadvantages. Students may begin to research products made as one-offs.
Students carry out a research piece into one-off products. They then begin production of their own one-off product, a charity key ring, this is produced by shearing a small sheet of mild steel, finishing the edges, drilling and adding stamped letter to promote the charitable cause. Quality control is applied to the product by students, so that the product is saleable in order to raise money for their charity.
