ANSWER QUESTION 5 ONLY
1. Using the following inventory data, conduct an ABC analysis of the inventory using the decision rule 80, 15, 5.
Item Cost Volume
Racing bike (RB) 1240 135
Tandem bike (TB) 725 120
Mountain bike (MB) 685 175
Standard bike (SB) 565 750
Child bike (CB) 125 600
2. Using the following data, conduct an XYZ analysis.
Racing bikes are mostly purchased from November to March and then sales fall off considerably April to October. The company has found that demand responds both to the season and the state of the economy in a fairly predictable manner.
The company has not been able to predict demand for tandem bikes. It seems that the purchases come in bunches but for no obvious reason.
Mountain bike demand has two peaks per year, one in early winter and one in early summer at the start of the vacation season.
Demand for standard bikes is somewhat less consistent than that for child bikes but is still fairly steady throughout the year with a slight rise before winter. Curiously, standard bike sales seem to mirror child bike sales but lag one month behind.
Child bikes are a common birthday gift for children. As a result, demand is fairly consistent throughout the year.
