3. Anticipate needs
Sensors on Carnival's Regal Princess cruise ship help take the guesswork out of what a guest might want next. The sensors sync up with an app that allows customers to make requests on demand, such as ordering a drink. With each request, the technology gets to work analyzing data to predict what the customer will need next. But proper usage requires a huge investment in staff training, says Jan Swartz, group president of Carnival brand Princess Cruises, per Fast Company. “If I want to share a glass of wine at sunset with my husband, I won’t have to interrupt the moment to make eye contact with a waiter. The app will tell her my order, and she’ll find me,” Swartz told the publication. “But [she] has to be trained to let me have that [private] moment as well.”
