Kieran works in the manufacturing industry and his company have just implemented LEAN production processes.

Explanation

2 'increase security of supply risks as there is less buffer stock held on site' is the correct answer. With Lean manufacturing there is little or no buffer stock held. This means that if a supplier doesn't deliver on time, the whole manufacturing process will have to come to a stop until new supplies arrive. A risk of Lean Manufacturing is that you become too reliant on suppliers, and if there is a scarcity of resources or an issue with the supply chain, you are more exposed. See p.26-27 for more information on Security of Supply Risks.
