Target wants to increase adoption of its new same-day delivery service, but it’s having trouble gaining traction with more cautious shoppers. Based on what you know about the five adoption factors (like compatibility, trialability, and observability), name one factor Target should focus on to reach the early majority. Explain why that factor would matter to early majority shoppers in this case.
