How to quickly identify functional requirements of Internet product 1

The identification of user needs plays an important role in Internet products, and also identifies the functional requirements for Internet product R & D. How can we quickly identify user needs as product features?

Generally, when a user needs to write or describe the document from the user's point of view, the document presented is also a more "Natural Language" descriptive, more inclined to business. User requirements are still at the upper layer of the product and have not reached the implementation layer. Functional requirements are the beginning of the product's functional reality. Developers pay more attention to the product's functional implementation, if you can achieve your needs. The two different requirements target different readers, so the focus will be different.

The functions of any system or product are shown in the following three aspects:
1. Why
Why is this function required? What is the significance of this function? This is an understanding of user needs.
Let developers understand the significance and role of this function. This is equivalent to the function overview.
2. Who
Who is using this function? Which roles are using this function? What specific user cases are there?
This is equivalent to system user classification recognition.
3. How
How can we achieve this function and achieve the user's goal? How can this problem be solved?
Operations for different users? How do I display function operation information and data? How can we achieve good interaction between users and the system?
 
Sending results can be considered based on the above three points, allowing you to quickly locate all aspects of functional requirements.
Each point is extended by tree-based thinking to consider functional requirements, subdivided into detailed functional points, performance requirements, and permission requirements, user management requirements form the first draft of the current functional requirements.
