Basic Agile Interview Questions

Q1. What is Agile, and how does it differ from traditional project management?

An Agile approach is an adjustable method of projects emphasizing frequent client involvement, response to changes, and gradual developments. In contrast to the inflexible planning used in the conventional approach, agile facilitates modifications and prioritized feature selection during the project execution period, improving adaptability and customer satisfaction.

Q2. What are the major premises of the Agile Manifesto?

The Agile Manifesto consists of four core values and twelve principles. Some key principles include

• Responding to change over following a plan,
• Prioritizing customer collaboration over contract negotiation
• Delivering working software frequently to satisfy customers
  
  

Q3. Can you explain the Scrum framework?

One of the Agile techniques that has emerged is a framework called Scrum. It involves small and autonomous groups with a limited period of operation within the duration known as sprints.

Key roles in Scrum include:

• Product Owner: In charge of specifying and arranging the product backlog, speaking on behalf of a customer/end-user.
• Scrum Master: This is the person on the team who ensures Scrum practices are followed and solves any problems encountered by the team.
• Development Team: Professionals organized into a self-directed team that would deliver the product.

Key Scrum events include:

• Sprint Planning: Every sprint starts with the planning phase, where new work is planned for the team.
• Daily Standup: Daily five-minute meetings about what is being done and any concerns.
• Sprint Review: The team shows what it has done by the end of every sprint to the stakeholders.
• Sprint Retrospective: A post-event discussion with the team about what worked and what failed.

Q4. What is a User Story in Agile, and how is it different from a traditional requirement document?

A User Story is a brief description, as seen by the user, about one feature. In most instances, it is usually presented in a plain, straightforward manner, like “As a [user role], I would like [action] because of [benefits].”

User stories foster communication among developers and stakeholders through user-centered requirements instead of elaborate technical descriptions. Unlike requirements documents, they are less formal, more customer-focused, short, detailed, and written in simple language.

5. How do you prioritize the product backlog in Agile?

A key component of the Agile process is prioritizing the product backlog, which guarantees that the team focuses on the most important and high-priority items first. Prioritizing the product backlog usually involves the following steps:

1. Product Owner Involvement: The Product Owner represents stakeholders' interests. They work with stakeholders to learn about their requirements, get their input, and match the backlog to the overarching business plan.
2. User Stories and Epics: Divide the project into epics and user stories for features or functionalities. These are fundamental components that provide fine-grained prioritization.
3. Value and ROI: Evaluate each epic or user story's contribution to the project, then rank them in order of importance based on ROI. The highest-value items or those meeting important business requirements should be at the top.
4. Dependencies: Take into account any connections between epics or user stories. Prioritizing tasks makes sense when they are dependent on one another's completion.
5. Risk mitigation: Prioritize items that deal with possible hazards at the outset of the development process. This guarantees that possible obstacles are addressed beforehand and aids in the management of uncertainty.
6. Consumer Feedback: Consistently take into account input from consumers or end users. Priority should be given to items directly addressing consumer feedback or needs to increase customer satisfaction.
7. Continuous Improvement: Setting priorities is a continuous process rather than a one-time event. The backlog should be regularly trimmed based on shifting business priorities, shifting market dynamics, and new prospects.

Q6. What is Agile's Definition of Done (DoD), and why is it important?

The 'Definition of Done' is a shared understanding within the team of what "done" means for each work item. It ensures that all necessary quality and acceptance criteria are met before an item is considered complete. Having a clear DoD enhances transparency and product quality.

The DoD is significant because of:

1. Consistency and Clarity: DoD points out to the stakeholders and team what "done" means for each increment. It eliminates uncertainty and determines clear expectations.
2. Quality Assurance: By defining specific benchmarks, the DoD ensures that every deliverable meets the required quality requirements. It covers aspects ranging from user experience to security, performance, and functionality.
3. Transparency: DoD enhances transparency by ensuring all parties involved can see the completion criteria. Transparency between team members and stakeholders also facilitates effective communication, which helps avoid misunderstandings.
4. Risk Reduction: A precise DoD reduces the chances that defects or issues may slip through undetected. It lowers the chances of problems when a work is released because it ensures that the team has covered all angles before declaring it complete.
5. Continuous Improvement: Teams can build upon the Department of Defense as a starting point and adapt to new requirements, best practices, and technology trends through regular evaluation and revision of DoDs. This way, they can change their understanding of "done" to fit the needs of a project.

Q7. How do you handle changing requirements in an Agile project?

Change requirements are always welcomed in Agile, as it is flexible enough to adapt. The project must include changes that should be prioritized and integrated on time. The team should also communicate freely with stakeholders to avoid conflicts involving changes related to the project.

Q8. What are the advantages and disadvantages of Agile?

Benefits of Agile include: 

• Faster delivery of value.
• Cost reduction through a shorter development cycle.
• Increased productivity resulting from continuous improvement.

• Customer Satisfaction: Demonstrating development progress to clients during Agile testing allows for adaptability and updates to requirements, ultimately ensuring customer satisfaction.

Q29. Explain the concept of Test-Driven Development (TDD) in Agile.

TDD is one of the practices in Agile, which refers to writing test scripts in advance before one types in code.

The process typically follows these steps:

• Write a Test: The first step in test-driven development is when developers create a failed test case that specifies what is supposed to be done next. The test is usually quite small to focus on a particular functional aspect.
• Write the Code: Developers will then write the minimum code required to make a failed test pass. Often, such code is concerned with the instant functions required.
• Run the Test: The test runs after the code has been written. It is successful if it goes through. Developers can only continue to change the code if they fail at testing.
• Refactor the Code: Since the test is being passed, the developer can redesign it and make it work at an increased performance level.

TDD remains critical in Agile since it assures that code is tested properly at the initial stage, minimizing the likelihood of introducing bugs and thus facilitating the smooth maintenance and development of a software system. Secondly, it drives developers toward expected behavior and requirements, which will result in the alignment of development with customer demands.

Agile Testing Definition of Done refers to the criteria or conditions that should be satisfied for a user story, feature, or task when handing it over as complete, ready, and fit for release. It works as a common definition of the quality and completeness targets that should be reached for every working item by members within the Agile team. The DoD is crucial in ensuring high-quality product delivery for several reasons:

• Quality Assurance: The DoD serves as a checklist that defines what attention to detail must be given when producing deliverables regarding functionality, performance security, and good user experience. By following the DoD, this team guarantees that the product stays a certain level of quality.
• Clear Expectations: The DoD is transparent on what constitutes a completed task and informs about expectations for the work. This clarity reduces the chances of misunderstandings within a team and makes everybody's understanding about what level of completeness each work item must achieve.
• Prevention of Technical Debt: Sticking to the DoD can prevent technical debt that constitutes cost rework or maintenance from using short-term solutions and compromising quality. The team reduces the risk of technical debt by identifying and resolving problems within the DoD.
• Incremental Improvement: The DoD is not stringent and can evolve over time due to lessons adopted plus changes in project requirements. Such flexibility fosters ongoing enhancement and enables the team to set a higher standard on quality rules in further releases.
• Collaboration and Communication: DoD is used for collaboration with team members developers, testers and product owners. It makes communication easier by giving people one kind of language and a common set of expectations so that everyone is always clear about what gets done in order for a task to be seen as finished.
• Customer Satisfaction: Adhering to the DoD ensures that the product delivered at the end of each iteration meets the agreed-upon quality standards. Regularly providing high-quality increments to customers enhances their satisfaction and confidence in the team's ability to deliver a reliable product.

• Scrum Master: Functions as a Scrum Master, removes barriers and pursues adherence to the principles of Scrum.
• Development Team: Soldiers responsible for providing the product’s increment.

Events:

• Sprint Planning: (Sprint Kick-off Meeting) A collaborative meeting at the beginning of a sprint where the team plans what work is to be done during that particular sprint.
• Daily Stand-up: The meetings are brief daily, with team members discussing.
• Sprint Review: In a final sprint meeting, the team will show all tasks performed during a period for stakeholders.
• Sprint Retrospective: A wrap-up meeting at the end of a sprint, where team members talk about what went well and did not go so well over that particular sprint. They also plan for changes to be made during subsequent iterations.

Artifacts:

• Product Backlog: A task definition list of features, improvements, and bugs, which is the work needed to be done on the project.
• Sprint Backlog: The team commits to deliver a subset of the product backlog during the sprint.
• Increment: This is the cumulative complete set of all product backlog items completed at the end of a sprint, which should be in a “potentially releasable” state.

Role of Scrum Cycle in Achieving Frequent Deliveries:

• Time-Boxed Sprints: Sprints are a set period of time (usually 2 – four weeks) during which the team performs on some predefined group of work. This limits the life cycle of each product, thus exerting consistent pressure on releasing new products.
• Iterative Development: The Scrum cycle focuses on the aspect of iterative development, where there are regular increments that are delivered at the end of each sprint. This permits ongoing feedback and allows stakeholders to have measurable progress often.
• Adaptability: The Scrum framework allows teams to adjust and update their product backlog at the final sprint based on changing requirements or priorities. This flexibility supports the delivery of such valuable features that can change with changed demands.
• Continuous Feedback: Events like the Sprint Review and Sprint Retrospective regularly occur to provide opportunities for continuous feedback for stakeholders and team members. This loopback assists in refining the product and enhancing developmental practices over time.
• Transparency: The Scrum cycle fosters openness by demonstrating the progress and obstacles encountered noticeably for everything related to teamwork and stakeholders through artifacts such as Sprint Backlog, burndown charts, or product increments. This openness creates trust and positive collaboration.
• Continuous Improvement: Sprint Retrospective is a special time for the team to review their processes and find areas to enhance their performance. This commitment to ongoing change creates more efficiency and effectiveness in future sprints.

Q48. What is the role of a Professional Scrum Master in Agile methodology, and how does it contribute to effective team collaboration and Agile practices?
