Hanson Cheng discusses automating key HR processes to improve efficiency. The document outlines 7 important HR functions to automate: 1) talent acquisition to streamline screening and improve the candidate experience, 2) onboarding for a smoother process and higher retention, 3) performance management for fair evaluations, 4) analytics to monitor metrics like engagement, 5) payroll to reduce errors, 6) leave calculation/approval for ease of use, and 7) offboarding to protect the organization. The benefits of HR automation include increased productivity, reduced costs and errors, and the ability to focus on more strategic work. Failure to automate risks wasting time and money through inefficiencies.
