9. Keeping it lean and mean • Assembling torches • Processes in the assembly sequence (in no particular order): • Inserting batteries • Screwing battery cover on • Inserting bulb • Screwing bulb cover on • Putting adhesive label on the side • Now devise: • Three assembly sequences that would work • Three assembly sequences that wouldn’t work • From the three that would work, why one might be slightly better than the others

10. Keeping it lean and mean • Three organisational models • Each student has a supply of all the components and assembles complete torches • Students are arranged in a row and each undertakes one stage in the assembly process, e.g. the first might put the batteries in the body, then passes it to the second, who screws the battery lid on, etc • Students are arranged in small teams, each of whom perform a sub-assembly. The part assembled torches are then stored temporarily before going on to the next sub-assembly. For example, the first sub-assembly might be the batteries going in and the lid being screwed on. The part assembled torches then await the next sub-assembly, such as the label being applied

11. Keeping it lean and mean • Lean manufacturing • Lean manufacturing is an approach to the management of production which uses the concept of “added value” for the customer to be the prime determinant for assessing the use of resources. • In other words, every stage and every use of time, skill or materials should be assessed in terms of whether it makes the product more valuable to the customer.

12. Keeping it lean and mean • Just in Time production • The “Just in Time” (JIT) approach to production aims to reduce the stock of components held by a manufacturer. The aim is to have the material needed arrive at the right time in the right place • This eliminates holding stocks that have been bought in, in advance, and need storage.
