Roadmapping is an effective tool for supporting innovation projects and business
strategies. It is easy to implement and can be used in many different ways. In an
international and globally operating company like Siemens, roadmapping offers
senior management a valuable aid for decision-making that is easy to understand in
any language. Siemens has developed a supportive approach to decision-making
known as the innovation business plan. The core of this innovation business plan
consists of a portfolio-based roadmapping process. The purpose of this paper is to
provide an overview of the above-mentioned portfolio-based roadmapping approach
within the innovation business plan and its compilation in the organization.
