This capstone focuses on examining key elements of employee-onboarding success in organizations. From the literature, the author extracted three crucial factors contributing to effective onboarding models, Relationship-Building, Organizational Support, and Communication, and proposed a hypothesis: These three key elements are contributing to onboarding success. Then, the author identified four outstanding employee onboarding models from Netflix, Twitter, LinkedIn, and Google, by using the criteria from several human resource specialized websites. In the analysis, the author examined the three elements in the four onboarding models and found out that all the factors contributed to employee onboarding success individually and collectively. Furthermore, the author proposed that “People” is a core value of a successful employee onboarding process for organizations. This paper strongly suggests that it would be worth pursuing with a larger study to examine the three elements and extract more factors.
