A4L is considering implementing a JIT production system. The following are the estimated benefits and costs of implementing JIT. Annual additional tooling costs would be 250,000 under JIT. Insurance, space, materials-handling, and setup costs, which currently total $610,000 annually, would decline by 20%. The emphasis on quality inherent in JIT production would reduce rework costs by 25%. A4L currently incurs $380,000 in annual rework costs. Improved product quality under JIT production would enable A4L to raise the price of its product by $2 per unit. A4L sells 44,000 units each year. REQUIRED: a) Calculate the net incremental benefit or cost to A4L if it adopts a JIT production system. Please show the costs or savings of each relevant item that forms the net total. (2 Marks) b) Currently there is only one supplier of parts for A4L. A4L has experienced shipping delays from this supplier on multiple occasions. Some employees do have training with JIT however, and would be comfortable with implementing it across the organization. Customers are indifferent as to whether JIT is implemented, but want to ensure that they receive good quality calculators without delays. Given both the quantitative information calculated in part a, and the information above, should A4L proceed with implementing JIT production? Please clearly state yes or no and provide 3 reasons (can be a combination of for and against) in this scenario. (6 Marks
