Stop escaping your past. How leaders turn legacy into a self-reinforcing advantage

Purpose This article helps executives determine when a firm’s legacy can support transformation and which constraint is preventing progress and must be resolved first. Design/methodology/approach The article develops a practitioner diagnostic – the Legacy Multiplier – by integrating strategy, corporate heritage, complementarity and platform insights with illustrative case evidence from legacy-firm renewal and failure. Findings Legacy firms rarely fail because they lack assets. They often stall because inherited assets remain disconnected. The framework identifies three viability conditions and five interdependent levers – narrative capital, organizational networks, adjacent value pools, value architecture and platform infrastructure. When aligned these levers can reinforce one another. A blocking-lever logic helps leaders identify the constraint preventing progress. Research limitations/implications The framework is an interpretive practitioner diagnostic; its causal claims require future empirical testing. Practical implications The diagnostic helps leadership teams shift from asking “what should we do next?” to “what must be fixed first?” Originality/value The article reframes legacy as a system-activation challenge and provides an executive tool for diagnosing when heritage supports renewal, when it constrains it and how to sequence action.
