A company has to decide whether to develop a new product, Prototype A, or the existing Product B. After discussions, it was agreed that the following scoring model would be helpful:
a. Using an appropriate method, evaluate the model and indicate whether your results support the case for developing a new product Prototype A or developing the existing Product B.
b. It has been agreed that the last two factors are of more importance. Evaluate the model again, but this time give 'product life expectancy' a weighting of three and 'expected returns' a weighting of two. Comment on your results.
