Roadmapping is an indispensable part of a long-term planning process in terms of responding to threats and keeping the competitive advantage. Arcelik is a household appliances manufacturer which develops its products and technologies. At Arcelik, the roadmapping process covers planning for market, product and technology.

Roadmaps are prepared for a five-year period with participation from different departments. Besides, technology roadmaps are studied in detail for each defined technology area. After the technology roadmaps are finalized, critical technologies captured from different technology roadmaps are consolidated under the related product roadmap. Market-product-technology roadmaps are approved and reviewed each year. After the approval, project charters and budgets are prepared.
