A roadmap, originally a travel itinerary, is now used more often to designate a simplified policy, strategy or action plan.
A roadmap is a structured (and often graphical) representation of a plan to reach a goal. The goal of a roadmap is to identify (critical) milestones and place them on a timeline.
Roadmaps are used in all kinds of fields for example economics, politics, technology etc.
Especially the technology roadmapping is often used in practice to support and strategic and long-term planning.
