A product roadmap is a strategic plan that outlines the vision for the product, the business objectives that need to be achieved, and the timeframes for delivering key milestones or features. It provides a high-level overview of the product's development, aligning the team and stakeholders on the product's direction and the expected delivery timeline.

Product vision defines what the product aims to achieve and the value it will deliver to customers or the business.

Business objectives outline what the product aims to accomplish in terms of business impact, like increasing revenue or improving customer satisfaction.

Timeframes indicate when key milestones or releases are planned to occur, ensuring that progress can be tracked and expectations set.

This high-level structure is essential for guiding product development and keeping stakeholders aligned, without delving into the specific details of design or project management, which are more suited for other planning documents.
