1) The production manager considers that by purchasing a testimonial, the level of awareness of the main product could increase significantly in the coming years. 2) The production manager uses cost accounting to calculate that the contribution margin of one of the products is EUR 50 per item. However, since consumers do not want to pay more than EUR 40 for this product, the production manager decides to stop production. 3) The production manager uses cost accounting to calculate that purchasing a system is only worthwhile if at least 100 pieces of the main product can be manufactured on it per hour. 4) The production manager considers using the residual value method instead of the market value method so that she can justify further production of the main product.
