Alliance Delivery in Practice: Building High-Trust Teams in Infrastructure with Marcia Medrano
To what extent is leadership success contingent on specific industry expertise? Marcia Medrano began her career in buildings, not transit. Yet, her experience developing and guiding teams, budgets, and procurement projects is proof that people management is not bound by sector—as long as you’re willing to make the most of the experts around you.In this episode of Master Builder, Riccardo and Shormila sit down with the Executive Vice President of Capital Projects at Metrolinx to explore what it takes to rise to leadership without pretending you’re an expert in everything. Marcia traces her path from architecture and vertical infrastructure to transit delivery and the core lesson that’s shaped her career: big infrastructure delivery is fundamentally about people—building trust, aligning teams, and getting things done. Marcia doesn’t hesitate to push back against conventions and assumptions. Choosing to leverage her parallel expertise rather than be daunted by a new sector, she often asks, “Why not?” Over and over, she sees the question unlock progress in new and exciting approaches for the infrastructure industry.The three experts hold a candid discussion about impostor syndrome and women in leadership, the superiority of alliance projects, and the importance of transparency on all sides of a major programme. They call out the danger of blindly following rigid structures and the shifting of the status quo as the Canadian infrastructure industry dives into ever larger and more ambitious projects. Throughout it all, Marcia champions a new understanding of steering the ship, and all the assets that come along with “leading like a woman.”Key takeawaysThe relationship-building and human connection that underpin infrastructure delivery success;How transparency drives success, however varied a team’s expertise and experience; Why incentivizing on-the-ground solutions and cooperation outweighs claims that stall progress at every turn;The importance of updated governance and project-wide empowerment on the owner side of collaborative contracts;What’s poised to change for women in infrastructure leadership.Quote“Challenging our own biases of the things that we know and the things that we don’t know is part of challenging the status quo.” - Marcia MedranoThe conversation doesn’t stop here—connect and converse with our community via LinkedIn:Navigating Major Programmes, Season 2 Episode 6 with Lawrence Rowland: https://navigatingmajorprogrammes.transistor.fm/s2/23 Follow Navigating Major Programmes: https://www.linkedin.com/company/navigating-major-programmes/Read Riccardo’s latest at www.riccardocosentino.comFollow Riccardo Cosentino: https://www.linkedin.com/in/cosentinoriccardo/Follow Marcia Medrano: https://www.linkedin.com/in/marcia-medrano-34a2962a/
