Implementing roadmapping guides improved strategy development for organizations not only to produce new products or services but also to navigate the entire process of organizational capability development to accelerate innovation. However, keeping roadmapping alive in organizations is challenging due to the complex integration process with a broad range of stakeholder involvement. While previous studies have contributed to staged development for managing roadmapping implementation, relatively little attention has been given to practical steps required in each stage for organizations to review the past, understand the current position in terms of where they are up to, and plan for the future to navigate the complex integration process efficiently and effectively. This article introduces a maturity model to guide the process of organization-wide roadmapping implementation. This is achieved by examining industrial cases to characterize practical steps, from the perspective of maturation, by which organizations implement and eventually integrate roadmapping into the organizational system and business cycles for technology and strategic planning. The Gerdsri three-stage model was utilized for discussion and analysis, aligning with the maturity model development. Six maturity levels have been characterized as follows: 1) Initial; 2) Defined; 3) Rolled Out; 4) Developed; 5) Standardized; and 6) Sustained.
