The purchasing manager
explained to Johann, ‘Let me remind you that eight months ago you instructed me
to reduce materials costs. I am doing this by taking advantage of the discounts
given by suppliers for larger orders. Often I order more than requested under the
assumption that we will need the material at some stage, so I get a discount and the
material is already in stock when we need it. Sometimes keeping things in stock
would take too much space or be too expensive, so then I might delay an order until
I can combine it with others to get bigger discounts.’
