Nonfunctional Requirements Test

Why this matters?

Nonfunctional requirements are critical to the success of any software project, as they define the quality attributes that determine the system's behavior, performance, and usability. This question helps assess a candidate's ability to identify and prioritize nonfunctional requirements for a project.

What to listen for?

Look for candidates who can describe their process for gathering nonfunctional requirements, including how they identify stakeholders, elicit requirements, and prioritize them based on their criticality and impact. Listen for their ability to balance conflicting requirements and constraints, and their understanding of how to communicate these requirements effectively to the development team.

Why this matters?

Nonfunctional requirements must be validated and tested to ensure that the system meets the desired quality attributes. This question helps assess a candidate's ability to evaluate and test nonfunctional requirements, and their understanding of how to measure and report the system's performance against these requirements.

What to listen for?

Look for candidates who can describe their approach to evaluating and testing nonfunctional requirements, including how they set up test environments, use test tools, and analyze test results. Listen for their ability to use metrics and benchmarks to measure the system's performance against these requirements, and their understanding of how to report the results to stakeholders.

Why this matters?

Performance is a critical nonfunctional requirement that determines the system's ability to handle user requests and process data. This question helps assess a candidate's experience with performance tuning and optimization, and their ability to improve the system's performance to meet nonfunctional requirements.

What to listen for?

Look for candidates who can describe their experience with performance tuning and optimization, including how they identify performance bottlenecks, use profiling tools, and optimize code and database queries. Listen for their ability to use caching, load balancing, and other techniques to improve the system's performance, and their understanding of how to measure and report the results.

Why this matters?

Security and privacy are critical nonfunctional requirements that protect the system and its users from unauthorized access and data breaches. This question helps assess a candidate's experience with security and privacy requirements, and their ability to ensure that the system meets these requirements.

What to listen for?

Look for candidates who can describe their experience with security and privacy requirements, including how they identify and classify sensitive data, use encryption and authentication mechanisms, and comply with relevant standards and regulations. Listen for their ability to perform security assessments and penetration testing, and their understanding of how to report and address security vulnerabilities.

Why this matters?

Usability and accessibility are critical nonfunctional requirements that determine the system's ease of use and accessibility to users with disabilities. This question helps assess a candidate's experience with usability and accessibility requirements, and their ability to ensure that the system meets these requirements.

What to listen for?

Listen for candidates who have experience with usability and accessibility requirements, including knowledge of relevant accessibility standards and guidelines. Look for their ability to describe their approach to designing and testing for usability and accessibility, including how they use user-centered design principles and conduct user testing with diverse populations. Additionally, listen for their understanding of how to address specific accessibility issues, such as providing alternative text for images, ensuring keyboard navigation, and optimizing color contrast for users with visual impairments. Finally, look for their ability to communicate and work collaboratively with designers, developers, and other stakeholders to ensure that the system meets usability and accessibility requirements.
