Checking Out Could Be Better EDIT 797 Fall 2005 Betty Wilkins
Background Self-checkout stations are common at many big chain retail establishments, including: Grocery stores (Giant Food) Hardware stores (Home Depot) Family oriented stores (Wal-Mart, K-Mart) Although advertised as easy-to-use, some customers are still intimidated by the perceived complexity of the workstation
Business Goals Better use of labor Increased throughput Customer loyalty Expanded selling space and display areas Lower shrinkage/loss rates High return on investment “an easier-to-use self- checkout machine could mean a bigger payoff. “
Personal Goals Control I know what I want I want to get in and out I want to monitor the entry of each item Minimize social contact I want privacy Don’t want to feel stupid or inept Understanding instructions Embarrassed by holding up line “…may have attempted to use self-checkout only to be befuddled by produce problems or embarrassed by a recording ordering them loudly to put that item back on the weigh station -- now. “
Data Collection Interviews Observations Actual Use
Primary Persona Pat is a 35-year-old professional male. Pat works long hours and usually eats on the run. When Pat shops at the grocery store, it’s usually for a few items at a time, just enough to fill the hand basket. Pat works regularly with computers and uses the Internet daily. Since he would rather be on the Internet, Pat would rather not have to cook on a regular basis, so whatever he buys at the grocery store is prepackaged.
Secondary Persona Terry is a 37-year-old mother of two who also works full time. She does the major grocery shopping for the family. To make time during her hectic day, she shops during lunch time to avoid crowds, or on the way home. Since she doesn’t have the children with her, she can stay focused and finish a significant amount of shopping more quickly.
Findings Based on the findings of the customer interviews, customers would be more inclined to use the self-checkout stations if: The screens were more intuitive The workstation design was more ergonomic and less awkward to command
