In which phase of the SDLC is the system actually built or purchased?
- Requirements Analysis
- Testing
- Implementation
- Maintenance
The implementation phase of the SDLC is where the system is actually built or purchased. It involves coding, development, and integration of the components to create the software system.
Discuss how continuous customer or stakeholder involvement in the Agile model might influence the quality assurance process.
- It delays the quality assurance process
- It has no impact on quality assurance
- It increases the need for quality assurance
- It reduces the need for quality assurance
Continuous customer or stakeholder involvement in the Agile model can increase the need for quality assurance. Their frequent feedback and evolving requirements necessitate ongoing testing and validation to ensure that the product meets their expectations.
_____ is a graphical UI design approach that focuses on usability, ensuring that users can easily interact with the system.
- Aesthetics
- Accessibility
- Ergonomics
- User-Centered Design
User-Centered Design is a graphical UI design approach that prioritizes usability. It focuses on creating interfaces that are intuitive and user-friendly, ensuring that users can easily interact with the system.
Envision a situation where a team is developing an e-commerce application that requires various services like payment, user authentication, and product management. Discuss the suitability of microservices architecture.
- Microservices are not suitable
- Microservices are suitable
- Microservices are suitable only for small applications
- Microservices are suitable only for large applications
For an e-commerce application that requires multiple services like payment, user authentication, and product management, a microservices architecture is suitable. Microservices allow each component to be developed and scaled independently, making it easier to manage and maintain different parts of the application.
In the context of software engineering, ______ ensures that the product is built according to the specified requirements, while ______ ensures that the product meets the user's needs.
- Verification, validation
- Maintenance, testing
- Documentation, coding
- Design, planning
In software engineering, verification ensures that the product is built according to the specified requirements, making it "right." Validation ensures that the product meets the user's needs and is "built right." These two processes work together to ensure the software's quality and alignment with both requirements and user expectations.
Envision a situation where a team using the Big Bang model reaches a critical point in development and realizes a major flaw in the current build. Discuss the potential steps the team might take and the challenges posed by the Big Bang model in resolving this issue.
- Steps: Detailed documentation, Challenges: Increased cost
- Steps: Extensive planning, Challenges: Slow response
- Steps: Rapid fixes, Challenges: Reduced quality
- Steps: Start from scratch, Challenges: Wasted effort
In a Big Bang model, if a major flaw is discovered, the team might have to start from scratch, which can result in wasted effort. The model's lack of incremental development and detailed planning can make it challenging to adapt and rectify critical issues efficiently.
How does the ISO/IEC 25010 standard classify software quality in terms of characteristics and sub-characteristics?
- It defines 8 characteristics and 25 sub-characteristics
- It defines 6 characteristics and 16 sub-characteristics
- It defines 7 characteristics and 31 sub-characteristics
- It defines 10 characteristics and 42 sub-characteristics
ISO/IEC 25010 classifies software quality into 8 characteristics and 25 sub-characteristics. These characteristics include functionality, reliability, usability, efficiency, maintainability, and others, each with their own set of sub-characteristics that further categorize quality attributes.
One common method of stress testing is to deliberately introduce ______ to observe how the system recovers and maintains stability.
- High traffic
- Low traffic
- Software updates
- Security vulnerabilities
One common method of stress testing involves deliberately introducing high traffic to observe how the system responds under stress. This helps assess the system's ability to maintain stability and recover from stress-induced issues.
How does regression testing ensure the consistent functionality of software after changes have been made?
- By retesting all test cases
- By testing only the modified code
- By retesting the entire system
- By comparing the new version with the previous one
Regression testing ensures the consistent functionality of software after changes by retesting the entire system. This practice helps identify any unintended side effects of code changes and ensures that the software continues to work correctly across all its features.
Fill in the blank: "_____ refers to the ability of software to be understood, learned, used, and attractive to the user when used under specified conditions."
- Scalability
- Reliability
- Portability
- Usability
Usability is all about the user experience. It refers to how easy it is for users to understand, learn, and use the software effectively under specific conditions. High usability is crucial for user satisfaction and productivity.
