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.
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.
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 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.
_____ 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.
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.
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.
Envision a situation where a software application needs to cater to both novice and expert users. How might you approach UI design to accommodate both user groups effectively?
- Create separate apps for novices and experts
- Implement a modular UI with user-defined customization
- Focus only on expert users since novices can adapt
- Provide extensive training for novice users
To accommodate both novice and expert users, a modular UI with user-defined customization is a strategic approach. This allows users to tailor the interface to their level of expertise and preference. Novices can start with a simple layout, while experts can access advanced features. This design balances usability and functionality.
In API development, the term "Endpoint" refers to a specific _____ that is exposed by the API for the purpose of processing API calls.
- Web server
- Database
- URL
- Function
In API development, an "Endpoint" is a specific URL that is exposed by the API for the purpose of processing API calls. Clients make requests to these URLs to interact with the API.
In software testing, what is the main objective of performing defect testing?
- To find and fix defects in the code
- To validate the requirements
- To verify the usability of the software
- To assess the performance of the software
The primary objective of defect testing is to find and identify defects or bugs in the software code so that they can be fixed before the software is released.
How does automation in software testing enhance the ability to detect errors and improve overall software quality?
- Automation eliminates all errors
- Automation speeds up testing without error detection
- Automation allows for repetitive and systematic testing
- Automation increases the cost of testing
Automation in software testing allows for repetitive and systematic testing, ensuring that the same tests are executed consistently. This not only detects errors more efficiently but also improves software quality by reducing human errors and providing faster feedback.
What role does data re-engineering play within the broader scope of software re-engineering?
- Data re-engineering is unrelated to software re-engineering
- Data re-engineering focuses on improving software security
- Data re-engineering involves restructuring and optimizing data storage and management within the software
- Data re-engineering only deals with data backup and recovery
Data re-engineering is a vital aspect of software re-engineering, focusing on the improvement of data storage, data management, and data-related processes to enhance the software's performance and efficiency.
