Q & A

What is the main topic discussed in the video?

The main topic is about recruitment in e-government applications, specifically focusing on the importance of functional and non-functional requirements.

Why do users often experience frustration with applications?

Users may feel frustrated when applications do not meet their expectations, often leading to error messages like 'failed to provide' due to server overload or unoptimized code.

How does the speaker describe the nature of software?

The speaker describes software as intangible and not easily visible, with much of its critical functionality existing behind the scenes.

What are functional requirements?

Functional requirements are user-oriented specifications that describe what the software must do, such as allowing users to view a countdown timer or requiring payment activation.

What are non-functional requirements, and why are they important?

Non-functional requirements pertain to system performance and constraints, such as response time and security protocols. They are important because they impact the overall usability and success of the software.

What role do stakeholders play in the requirements gathering process?

Stakeholders are crucial in the requirements gathering process as their involvement ensures that the end product meets user needs and expectations.

What is the significance of the requirements elicitation process?

The requirements elicitation process is significant as it involves researching user needs, clearly specifying those needs for developers, and validating requirements with stakeholders to ensure alignment.

How is documentation important in the development process?

Documentation is important because it provides a detailed account of project scope and deliverables, helping to prevent scope creep during development and ensuring all parties are aligned.

Can you provide an example of a non-functional requirement mentioned in the video?

An example of a non-functional requirement is the system's ability to handle 10,000 requests per second, especially during high-traffic periods like promotions.

What conclusion does the speaker reach at the end of the video?

The speaker concludes by expressing hope that the information shared has been enlightening and offers apologies for any errors made during the presentation.
