6. Aztec Furnishings makes hand-crafted furniture for sale in its retail stores. The furniture maker has recently installed a new assembly process, including a new sander and polisher. With this new system, production has increased to 90 pieces of furniture per day from the previous 60 pieces of furniture per day. The number of defective items produced has dropped from 10 pieces per day to 1 per day. The production facility operates strictly eight hours per day. Evaluate the change in productivity for Aztec using the new assembly process. Answer: Using only the non-defective production, productivity has increased from (60 - 10) = 50 pieces per day to (90 - 1) - 89 pieces per day. Change in productivity =(89 - 50/50 x 100% = 78% There is a 78% increase in productivity using the new assembly process. Assignment: For submission, in Excel, do Chapter 2, problem #6 in the Problems section (not Discussion Questions) (rubric B). Compute before and after productivity using Excel formulas. Show the percentage change in productivity using the new assembly process. Think about whether rejected material should be included in the output (i.e., if you were a manager, would you accept defective products from your workers? if you were a customer, would you buy defective goods?). Save the file as "buddy team # - Ch 2-6" where "#" is the assigned number of your buddy team. Upload the finished file to Canvas
