- What is just in time delivery?arrow_forwardTeloxy Engineering (A) Teloxy Engineering has received a onetime contract to design and build 10 000 units of a new product. During the proposal process, management felt that the new product could be designed and manufactured at a low cost. Some members felt that it would be more economical to purchase the product for R200 each in the marketplace, with an extra R20 per unit handling of the 10 000 units. The Management team set up a meeting with the manufacturing team to see if they can manufacture the component at a cheaper price than buying it from the outside. The manufacturing team informs them that it can produce a maximum of 10,000 units, just enough to fulfil the contract. The setup cost will be R100 000 and the raw material cost is R120 per component. Since Teloxy has never manufactured this product before, manufacturing expects the following defects: % defective 10 20 30 40 Probability of occurrence (%) 10 20 30 25 15 All defective units must be removed and repaired at a cost…arrow_forwardHow do we calculate slack?arrow_forward
