nit exercise 4 1) Explain how Product Lifecycle Management impacts product design. 2) Use exponential smoothing with trend adjustment to forecast demand for period 11. Let a = 0.5, B = 0.3, and let the initial trend value be 12 and the initial forecast be 200. Period 2 3 4 5 6 7 8 9 10 Actual Demand 200 212 214 222 236 221 240 244 250 266 3) A company is trying to decide whether to make-or-buy a part. Purchasing the part would cost them $1.50 each. If they design and produce it themselves, it will result in a per unit cost of $0.75. However, the design investment would be $50,000. Further, they realize that for this type of part, there is a 30% chance that the part will need to be redesigned at an additional cost of $50,000. Regardless of whether they make-or-buy the part, company will need 100,000 of these parts. Using decision trees analysis and EMV, what should company do? Show the decision tree. 4) A company producing apps for a social networking site is deciding which path to pursue. The first is to create an app that has universal appeal but faces a crowded market. This app, A, would have sales of 100,000 copies at $1 each under ideal conditions, but under tough conditions would have sales of only 60,000 copies at $.80 each. The other app, B, would have sales of 500,000 units at $.50 each under ideal conditions but sales would be reduced to 10,000 units at $.50 each under tough conditions. If ideal and rough conditions occur with the same frequency, which app should the company produce? Note- both apps cost the same to develop
