Many leading organizations are proactively leveraging technology as part of organization-wide strategies for achieving “Diversity, Equity and Inclusion (DEI) 4.0”. However, there are often unintended consequences and risks when implementing new technology tools. This toolkit highlights the opportunities and outlines the challenges specific to the greater use of technology in the service of DEI efforts. These areas are explored through three lenses: 1) Talent Sourcing and Selection, 2) Organizational Analysis and Monitoring, 3) Employee Experience, Reward, and Development. For the Talent Sourcing and Selection lens, a few challenges discussed include a) addressing bias in job advertisement – where the language used might bias the application process and limit the pool of applicants. b) tapping into talent pools of diverse candidates – where existing approaches to posting roles might fail to reach diverse talent pools, and c) identify best-fit candidates based on merit and skills – interview process might introduce a range of biases into the hiring process. The insights throughout this report can be used to drive DEI through technology while minimizing unintended consequences.
