Review Questions

• How does the systematic approach of software engineering enhance the quality of software products?
  • The systematic approach in software engineering involves structured processes such as requirements analysis, design, implementation, testing, and maintenance. By following these well-defined steps, teams can identify and address potential issues early in development, which leads to higher quality outcomes. This structure also facilitates better communication among team members and stakeholders, allowing for clearer expectations and more effective collaboration.
• Discuss the role of agile methodology in modern software engineering practices.
  • Agile methodology plays a significant role in modern software engineering by promoting adaptability and responsiveness to change. By breaking down projects into smaller sprints, teams can deliver incremental updates and gather user feedback quickly. This iterative process not only helps in refining requirements but also allows for continuous improvement throughout the project lifecycle, making it easier to align the final product with user needs.
• Evaluate the ethical considerations that software engineers must take into account when developing new technologies.
  • When developing new technologies, software engineers must evaluate ethical considerations related to user privacy, data security, and accessibility. They should ensure that their software solutions do not inadvertently harm users or society by perpetuating biases or excluding certain groups. Furthermore, engineers need to consider how their work impacts users' rights and freedoms, striving to create responsible technologies that contribute positively to society.
