What is a one-pager? Examples, rules, template

A one-pager is an essential tool for product managers to communicate effectively across various business departments, providing a concise and strategic overview of a product, project, or idea. It fosters alignment and clarity among stakeholders by presenting key details, objectives, and value propositions in a single-page format. Unlike traditional documents such as project plans, product requirements documents, and business cases, which can be cumbersome and outdated, a one-pager is agile and adaptable to modern software development practices. Popular models for creating one-pagers include Amazon's press release approach, the Shape Up pitch document, and the Lean Canvas, each offering unique advantages and challenges. The one-pager's main purpose is to ensure all departments are aligned and can support the product development process efficiently, with the document being continually shared and updated to incorporate feedback and maintain alignment across the organization.
