Key components at a glance

A strong product specification follows a clear and predictable structure that helps teams stay aligned throughout development. Each section plays a distinct role in describing what the product is and how it should function. The structure can vary depending on the industry or company, but the most effective specifications include these key parts:

• Product summary: Explains what the product is, why it exists, and who it serves.
• Scope: Defines what will be included and excluded from development to prevent unnecessary expansion.
• Functional and technical requirements: Describe how the product should work, which systems it depends on, and any key integrations or technologies.
• Design specifications: Detail the product’s appearance and user experience, from interface layout to materials or visual style.
• Performance criteria: Establish measurable standards, such as response time, durability, or energy efficiency.
• Acceptance criteria and risks: Indicate how success will be measured and identify potential challenges early in the process.^[1]
