In the iterative development method, software development cycles are repetitive until your team achieves a final product, while incremental development segregates system functionality into increments and portions.
Through cross-discipline work, functionality segments are delivered each increment from requirements to deployment.
10. What are burn-down and burn-up charts?
Burn-up charts show completed work, while burn-down charts indicate remaining work in a project.
11. What is the Scrum of scrums?
If a project has several teams working on it, each team leads its meeting. For coordination among various teams, a separate meeting is organized, and it is called Scrum of Scrums. Each team is represented by an ambassador in such a meeting.
12. What are some primary agendas for scrums of scrums?
The primary points in such a meeting include; team's progress since the last meeting, tasks to be completed before a consequent meeting, and challenges faced by the teams while completing previous tasks.
13. Can you explain pair programming and its benefits?
Pair programming is a combined team effort where one programmer writes while another one reviews a code.
Pair programming improves the quality and facilitates the transfer of knowledge. Chances of mistakes are fewer as there are two people simultaneously working on it.
14. What is test-driven development?
In test-driven development, developers create small codes to pass an automated test instance describing your new function then refactors the encryption later to meet required standards.
15. What is the velocity of a sprint?
A velocity is a development tool used for approximation of work speed and expected time for project completion.
You calculate it by reviewing work completed during earlier sprints.
16. List principles of the testing methodology?
The principles include;
• Customer satisfaction
• The developers work together as a team
• Customers should be welcome to changes
• It Promotes sustainable development
• Focusing on essence instead of lengthy documentation
• Encourages face to face communication
17. Qualities that a good tester must-have?
A competent tester should;
• Be aware of all principles, concepts, and values
• Be capable of understanding requirements fast
• Prioritize work on a requirement basis
• Have excellent communication skills.
18. What is Zero sprint?
Zero Sprint is setting up done before starting an initial first sprint, for example, by preparing backlog and setting up an environment for development. Thus, it is a pre-step to diving into your first sprint.
19. What does story point mean?
A story point is a unit used to estimate the effort and time needed to finish a backlog.
20. Why are user stories not estimated using working hours?
Estimating user stories by working hours compromises product quality and relies heavily on budget and management cost. Hence, it is mandatory to estimate under terms of workforce and complexity of a project.
21. Explain the roles of a Scrum Master.
A master is a leader of a team. They are responsible for ensuring the principles and values are observed and that processes agreed upon are followed.
22. List of Most critical Matrices?
The critical matrices include;
• Velocity
• Defect removal awareness
• Work category allocation
• Sprint burn-down matric
• Cumulative flow diagram
• Delivery of business value
• Defect resolution time
• Time coverage
• Clearing virus picture
• Scheduling a fix
• Fixation of defect
• Report for resolution
23. Challenges involved while developing Software?
Some challenges include;
• Completion of each feature before moving on
• Numerous tests and client involvement
• A lot of preparation is required
• Ensuring all codes work fine to have a working application
24. A product roadmap means?
It is a holistic view of a product and its features that help to create a product vision.
25. What is a product burn-down chart?
A product burn-down chart is a graph description of implemented product backlog.
26. What is a sprint burn-down chart?
It is a graphic representation of implemented number of sprints and non-implemented ones within the cycle.
27. What is a defect burn-down chart?
It is a representation of a number of defects identified and removed.
28. What is Release burn-down chart?
A release burn-down chart is a graph illustrating pending releases.
29. What is refactoring?
Refactoring is modifying a cypher without changing its functionality to improve its performance.
30. What is Application Binary Interface?
It is an interface that compiles a low-level interface between the operating system and an application.
31. What is a tracer bullet?
The tracer bullet tool examines end-to-end process feasibility.
32. What is increment?
It can be defined as total backlog items of a product during a sprint. It is cumulative and includes increment values of a previous sprint.
33. How to manage remote teams?
Remote project management tools help with remote teams management by helping you know in what way to bring them on board and manage resources, people, and tools.
34. What does impediment mean?
Impediments are obstacles that hinder smooth workflow resulting to team underperformance.
