Software Engineering 7 - Exam part 3 Flashcards
Agile development methods focus on more efficient production. The goal is to develop methods to increase quality, reduce costs, increase productivity, and job satisfaction.
Describe how the objective “increase quality” is addressed in Scrum
Increase Quality
Scrum emphasizes building high-quality increments through several key practices:
Definition of Done (DoD)
Continuous Feedback and Inspection
Frequent Testing and Iterative Development
quality is increased through continuous feedback and testing
Agile development methods focus on more efficient production. The goal is to develop methods to increase quality, reduce costs, increase productivity, and job satisfaction.
Describe how the objective “reduce costs” is addressed in Scrum
Reduce Costs
Scrum helps reduce costs by minimizing waste and ensuring efficient use of resources:
Prioritization of High-Value Work
Early Detection of Issues
Reduced Rework through Clarity
costs are reduced by focusing on valuable work and early issue detection
Agile development methods focus on more efficient production. The goal is to develop methods to increase quality, reduce costs, increase productivity, and job satisfaction.
Describe how the objective “increase productivity” is addressed in Scrum
Increase Productivity
Scrum focuses on maintaining a productive team environment through efficient workflows:
Time-Boxed Sprints and Clear Goals
Cross-Functional Teams
Sprint Retrospectives for Continuous Improvement
productivity improves due to time-boxed sprints and cross-functional teams
Agile development methods focus on more efficient production. The goal is to develop methods to increase quality, reduce costs, increase productivity, and job satisfaction.
Describe how the objective “increase job satisfaction” is addressed in Scrum
Increase Job Satisfaction
Scrum fosters job satisfaction by promoting collaboration, autonomy, and recognition:
Self-Organizing Teams
Recognition and Frequent Wins
Supportive Environment
Work-Life Balance
job satisfaction rises from autonomy, collaboration, and recognition
Explain Definition of Done (DoD) in scrum
The Definition of Done specifies the criteria that each product increment must meet (e.g., passing tests, code reviews, documentation).
Example: A software development team ensures that all features meet testing and quality benchmarks before being considered “done,” which prevents bugs from accumulating.
Explain Continuous Feedback and Inspection in scrum
Scrum includes frequent Sprint Reviews where stakeholders provide feedback, and Sprint Retrospectives where the team reflects on improving processes.
Example: If stakeholders notice a feature that doesn’t align with their needs during a review, the team can adjust quickly instead of waiting until the end of the project.
Explain Frequent Testing and Iterative Development in scrum
By delivering small, tested increments at the end of each sprint, defects are identified and resolved early.
Example: A game development team tests new levels after each sprint to ensure smooth gameplay before expanding to more complex levels.
Explain Prioritization of High-Value Work in scrum
The Product Owner ensures that the most valuable features are prioritized in the Product Backlog. This prevents the team from spending time on low-priority features.
Example: A mobile app team focuses on releasing a payment feature first, as it directly contributes to user satisfaction and monetization, instead of developing secondary features like theme customization.
Explain Early Detection of Issues in scrum
Issues and bugs are identified early through continuous testing and stakeholder feedback, reducing expensive fixes later in the process.
Example: In a web development project, the team catches a performance issue during the second sprint rather than discovering it after the product launch, avoiding costly rework.
Explain Reduced Rework through Clarity in scrum
Regular communication in daily stand-ups ensures that the team remains aligned, preventing costly misunderstandings.
Example: A marketing automation platform development team synchronizes daily, ensuring their API implementation matches the external service specifications without unnecessary backtracking.
Explain Time-Boxed Sprints and Clear Goals in scrum
Sprints are time-boxed with specific goals, ensuring the team focuses on a manageable set of tasks without multitasking.
Example: A development team sets a sprint goal to complete a customer dashboard feature in two weeks rather than tackling unrelated items, leading to faster delivery.
Explain Cross-Functional Teams in scrum
Scrum teams are cross-functional, meaning they include developers, testers, and designers, which reduces handoffs and delays.
Example: A data visualization team includes both back-end and front-end developers, ensuring that new charts are built and styled within the same sprint.
Explain Sprint Retrospectives for Continuous Improvement in scrum
Teams hold retrospectives to identify and resolve productivity blockers after each sprint.
Example: A team notices that their build times slow down development, so they implement continuous integration tools to streamline the process.
Explain Self-Organizing Teams in scrum
Scrum teams decide how to approach their work and manage tasks, giving members autonomy and a sense of ownership.
Example: A software development team assigns tasks among themselves based on their strengths and preferences, creating a balanced and fulfilling workload.
Explain Recognition and Frequent Wins in scrum
By delivering working increments at the end of each sprint, team members can see the immediate impact of their work and celebrate their progress.
Example: After delivering a new feature for a shopping app, the team receives positive feedback from the Product Owner, reinforcing their sense of accomplishment.
