Along with the generation’s oft-recounted “delayed adulthood,” it appears there’s been some delayed development of basic skills among millennials as well, and a wave of companies want to be resources of information instead of just sources for products. Brands including The Home Depot, Procter & Gamble and Sherwin-Williams have all started offering classes and online tutorials to teach such basic skills as using a tape measure, mopping floors and mowing lawns. Millennials have shown they are eager to learn, so it might be worth giving some thought to what else millennials might not know how to do — cleaning silver, changing a watch battery, stringing beads—and how to incorporate those activities into offerings in a non-condescending way.
