For more than two decades, Global Capability Centres have been closely associated with one highly visible measure: headcount. While organisations have also tracked value creation, capability development, innovation and business impact, growth in the sector has often been described, compared and celebrated through the lens of workforce expansion. This book examines what happens when capability, output and decision-making begin to grow faster than workforce size. Drawing on industry data, policy developments, organisational design and first-principles analysis, After Scale explores how authority, accountability and decision rights become more important than scale in the next phase of the GCC model. Written for business leaders, GCC executives, policymakers and enterprise decision-makers, the book offers a practical framework for understanding what survives, what changes and what must be built next.
