including “doing nothing” Enter payoffs at end of branch Determine the expected value of each branch and “prune” the tree to find the alternative with the best expected value 47 Decision Tree Example (.4) Purchase CAD High sales (.6) Low sales Hire and train engineers (.4) High sales (.6) Do nothing Low sales 48 Figure 5.14 Decision Tree Example (.4) Purchase CAD High sales (.6) Low sales Hire and train engineers $2,500,000 -
