Katharine is the owner of Bikes, a company that produces high quality cross-country bicycles. Bikes participates in a supply chain that consists of suppliers, manufacturers, distributors, and elite bicycle shops. For several years Bikes has purchased titanium from suppliers in the supply chain. Bikes uses titanium for the bicycle frames because it is stronger and lighter than other metals and therefore increases the quality of the bicycle. Earlier this year, Bikes hired Michael , a recent graduate from State University, as purchasing manager. Michael believed that he could reduce costs if he purchased titanium from an online marketplace at a lower price. Bikes established the following standards based upon the company's experience with their previous suppliers. The standards are as follows: Cost of titanium $17 per pound Titanium used per bicycle 8 lbs. Actual results for the first month using the online supplier of titanium are as follows: Bicycles produced 700 Titanium purchased 7,600 lb. for $121,600 Titanium used in production 6,600 lb. pop-up content ends 1. Compute the direct materials price and efficiency variances. 2. What factors can explain the variances identified in requirement 1? Could any other variances be affected? 3. Was switching suppliers a good idea for Bikes? Explain why or why not. 4. Should Michael 's performance evaluation be based solely on price variances? Should the production manager's evaluation be based solely on efficiency variances? Why is it important for Katharine to understand the causes of a variance before she evaluates performance? 5. Other than performance evaluation, what reasons are there for calculating variances? 6. What future problems could result from Bikes' decision to buy a lower quality of titanium from the online marketplace? pop-
