What is the difference between the definition of user requirements of mobile applications and traditional system analysis?

The difference between the definition of user requirements of mobile applications and traditional system analysis is that the details of system requirements are different, the emphasis is different and the angle is different.

First of all, the details of system requirements are different.

1. Definition of user requirements: The definition of user requirements has no clear details of system requirements.

2. Traditional system analysis: Traditional system analysis has a clear and definite detail of system requirements.

Second, the emphasis is different.

1. User demand definition: The focus of user demand definition is what the mobile application system needs to do.

2. Traditional system analysis: The focus of traditional system analysis is to reasonably subdivide what mobile application systems must do.

Third, the angle is different.

1. User demand definition: User demand definition defines the system demand from the external behavior of the system, that is, the user's point of view.

2. Traditional system analysis: Traditional system analysis analyzes system requirements from the perspective of users and developers.
