Understanding what requirements define

Product requirements describe what the product must achieve to meet user and business needs. They focus on outcomes, not implementation. A well-written requirement answers the question “what should the product do?” rather than “how will it do it?” For example, a requirement might specify that users should be able to securely store and access personal data or track orders in real time.

Requirements are shaped by customer feedback, market research, and stakeholder goals. They outline expected features and functions, helping teams align around a common vision early in the process. Because they deal with the big picture, they are intentionally flexible and can change as new insights appear. Their value lies in creating clarity about goals before technical details are defined, ensuring that what is built serves real user and business priorities.^[1]
