Diversity isn’t about achieving magic numbers; it is about building and sustaining a high-performing workforce. When used responsibly, however, numbers can help us understand the diversity problem and our progress toward solutions. Numbers gathered by the National Science Foundation tell us that even when women and under-represented minorities make it through the STEM education pipeline, they leave the engineering workforce disproportionately often when compared to their white male counterparts. Fortunately, the numbers also help us identify causes of – and potential solutions to – this problem. Building on the outcomes of the TMS Summit on Diversity in the Minerals, Metals, and Materials Professions (DMMM1), we will discuss strategies, tools, and resources that educators, employers, and individuals can use to maximize retention and success in the context of a diverse engineering workforce. In the process, we will dispel a few myths, exchange some anecdotes, and enjoy a lively discussion.
