As western economies have transformed from industrial-based to service-based, trades and vocations have smaller roles.[7] However, specific hard skills and mastery of particular skill sets, with a focus on digital literacy, are in increasingly high demand.[2][3] People skills that involve interaction, collaboration, and managing others are increasingly important.[4] Skills that enable people to be flexible and adaptable in different roles or in different fields, those that involve processing information and managing people more than manipulating equipment—in an office or a factory—are in greater demand.[9] These are also referred to as "applied skills" or "soft skills",[10] including personal, interpersonal, or learning-based skills, such as life skills (problem-solving behaviors), people skills, and social skills.
