How would you approach creating a product roadmap without prior knowledge of the product?

To build a product roadmap with no prior knowledge, I'd start by immersing myself in the business. This involves understanding the company's mission, vision, and strategic goals. I'd then conduct thorough stakeholder interviews—talking to leadership, sales, marketing, engineering, and customer support—to gather diverse perspectives on the product's current state, market position, and future opportunities. Simultaneously, I'd dive into understanding the target customer, their needs, pain points, and existing solutions. Analyzing competitor landscapes and market trends is also crucial. By synthesizing this information, I can identify key themes, define strategic objectives, and then prioritize potential initiatives based on their potential impact and alignment with business goals, ultimately forming the foundation of the roadmap.
