Modernization is often treated as a technical challenge, yet its success is shaped by people. Drawing on conversations from the Mainframe Coven podcast, we'll examine a recurring theme: modernization efforts are weakened when certain voices and experiences are overlooked, particularly those of women and other underrepresented practitioners whose work often sustains critical systems. We’ll share real stories and practical approaches to strengthen knowledge transfer, maintain engagement, and foster environments free from gatekeeping. This session is for anyone seeking to align modernization initiatives with human-centered practices and build resilient, sustainable mainframe teams.
