In software engineering, requirements analysis refers to all the work that is required to describe the purpose, scope, and definition of a new system when creating a new or changing existing computer system. Requirement analysis is a key process in software engineering.
In this process, the system analyst and the software engineer determine the customer's needs. Only when these needs are identified will they be able to analyze and seek solutions to t

A complete understanding of software requirements is critical to the success of software development efforts, and the task of requirements analysis is to discover, refinement, model and standardize processes. Report the functionality and performance requirements of the software to potential users, enabling them to determine whether the software

However, if the project has been signed a contract, there will be a problem of whether to continue with the original contract, suspension, or change the payment conditions. For internal projects, the so-called cost is the problem of how tired the engineering staff are and when tired. At this time, it is best for Software Engineering practitioners to understand that, before they are exhausted, the boss, and those colleagues who are ignorant of technology
