Questions & Answers

Q: What is Requirement Engineering in the software development lifecycle?

Requirement Engineering is the phase where requirements for a software product are gathered from users and developers to define the problem statement and understand the needs of the product.

Q: What are functional requirements in software development?

Functional requirements specify what the software is supposed to do and how it should work. Examples include capturing images in a camera or searching records in a search engine.

Q: What are non-functional requirements?

Non-functional requirements are aspects of the software that are not directly related to its functionality but are necessary for its proper functioning. These can include security measures, logging capabilities, and storage requirements.

Q: Why are user interface requirements important in software development?

User interface requirements focus on the direct appeal of the software to users. An effective user interface that is easy to operate, responsive, and handles operational errors well can greatly enhance user satisfaction and acceptance of the software.

Summary & Key Takeaways

• Requirement Engineering is the first phase of the software development lifecycle, where requirements are gathered from users and developers to define the problem statement.

• Functional requirements define what the software is supposed to do and how it will function, such as capturing images or searching records.

• Non-functional requirements include aspects like security, logging, and storage, which are necessary for the proper functioning of the software.

• User interface requirements relate to the appeal and usability of the software, including factors like the interface's ease of operation, responsiveness, and error handling.
