What is the role of fast feedback in product development?

• A. It reduces uncertainty
• B. It delays decisions
• C. It accelerates knowledge
• D. It increases documentation

Answer: (C)

Fast feedback is about turning real-world input from users, customers, and the product environment into validated learning quickly. When teams get rapid input, they convert assumptions into knowledge faster, so they can adjust the product, design, and priorities without waste. This learning drives faster, evidence-based decisions and reduces risk because choices are based on actual data rather than guesswork. While faster feedback does help reduce uncertainty, the clearer description of its role is that it accelerates knowledge, enabling you to act sooner and more confidently. It also supports lean practices by avoiding unnecessary documentation and focusing on delivering working increments.
