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.

In this composition, team members can work together on various aspects of a project that encourages the collective problem-solving approach and shared responsibility for tasks.
• Iterative Development: Agile uses iterative development cycles, so-called sprints in Scrum, with small functional increments of a product being delivered regularly. This process is iterative because collaboration and feedback can occur frequently, ensuring the final product matches stakeholders' expectations.
• Frequent Communication: Agile methodologies focus on consistent and open communication. Daily stand-up meetings, sprint planning sessions, review meetings, and retrospectives offer regular opportunities for team members and stakeholders to discuss current progress ratings challenges or impediments they have encountered together with any needed adjustments.
• Customer Involvement: In agile, there is a high level of customer collaboration throughout the development process. A product that reflects customers' true needs and expectations can be achieved by regularly integrating their feedback through interactions with them.
• Product Backlog Prioritization: The Product Owner works with stakeholders to develop and rank the product backlog. This collaboration ensures that the team focuses on the most valuable and high-priority features to align with all business goals in terms of development.
• Adaptability to Change: Agile welcomes change and encourages evolving requirements, even at a late development stage. This flexibility enables teams to adapt quickly when getting a new insight or priorities change, leading to the spirit of collaborative behaviour that adapts easily due to problems related to projects being in constant evolution.

Q14. What are the most typical Agile metrics for evaluating a project’s performance?

Common Agile metrics include:

• Velocity (the amount of work completed in a sprint).
• Burn-down and Burn-up charts (visualizing work progress).
• Lead Time (time from the start to the completion of a user story).
• Cycle Time (time from when work starts until it's delivered).

These metrics help teams track progress and identify areas for improvement in their Agile processes.

Agile Interview Questions- Methodology [Basic+ Advanced]

Agile methodology is an adaptable and iterative approach to software development that prioritizes adaptability and customer collaboration. It breaks down projects into smaller, manageable increments known as sprints, where cross-functional teams work collaboratively to deliver working software. Agility provides immediate information, and change can be done during the project. Value to customers within a short period is the main focus. Unlike traditional sequential development methods, it fosters a flexible project management method.

Q41. What are the core principles of Agile methodology, and how do they guide software development practices?

Agile methodology is guided by the following:

• customer collaboration,
• responding to change,
• delivering working software and
• individuals and interactions over processes and tools.

These principles prioritize flexibility, customer satisfaction, adaptability, and human-centric approaches in agile software development practices.

Q42. What is the significance of planning poker in Agile project development, and how does it contribute to project estimation and prioritization?

Planning Poker refers to a project planning process that calculates values and prioritizes product elements in an iterative model such as User Story. This is a collaborative process that includes team members like developers and testers as the key decision markers.

Here's how it contributes to project estimation and prioritization:

• Team Involvement: Planning poker involves every team member in the estimate process. This enables the sharing of perspectives from all the parties and hence promotes collaboration, discussion, and consensus-building among peers.
• Reliable Estimates: The team members need to discuss various perspectives on the same scenario to improve the efficacy and reliability of their estimated efforts of performing the task.
• Prioritization: Moreover, planning poker can be applied for purposes of both estimating and prioritizing. The team will determine the priority of each backlog item by assigning story points (effort estimates) as an estimate of its value and complexity.
• Transparency: It is a simple process that is transparent, and all people's inputs are considered. By so doing, this enhances stakeholders' and team members' understanding of what is required, making them all understand on the same frequency.

Planning Poker helps establish a common ground for communication within an Agile team regarding project development.

Q43. What are the key principles of the Crystal Methodology, and discuss how it aligns with Agile development methodologies?

Key Principles of Crystal Methodology:

• People-focused: Underscoring the need for qualified people and proper interaction in a project team.
• Frequent Delivery: Continuously delivers workable software for regular feedback provision and accommodations in response to emerging changes.
• Reflective Improvement: Motivates team members to assess their process and provide feedback to refine practice.
• Sensitivity to Project Complexity: It takes a flexible outlook in its procedures, depending on the degree of complexity, and offers suitable strategies for every range of complexity.
• Early Delivery of High-Value Features: Provides business value by introducing new features early in the development cycle.

Alignment with Agile:

Crystal Methodology embodies aspects of individual and interaction, working software, customer collaboration, and responsiveness to changes, which formulates the basic Agile principles. The first approach emphasizes flexibility, adaptation, and development in a cyclical way to add value to the customer.

Q44. Explain the importance of iterative development, and how it contributes to delivering successful software projects?

• Importance of Iterative Development in Agile and Contributions to Successful Software Projects: Agile development employs an iterative approach, breaking down the project into small, manageable iterations or sprints.
• Early and Continuous Feedback: This iterative development approach facilitates frequent reviews of deliverables during their ongoing production. Stakeholders give input along the way, thus decreasing the chances of misinterpretations and achieving what customers expect.
• Adaptability to Change: Iterations allow modification by emerging requests. The ability to adapt ensures that the software is tuned to customers’ requirements and the changes in the market.
• Risk Mitigation: Breaking down functions into manageable chunks permits a continuous risk reduction throughout development. It helps to cushion against the effect of unexpected events, resulting in increased project predictability.
• Faster Time-to-Market: It produces a potentially shippable product increment for each iteration. These facilitate frequent releases that enable quick time-to-market and positioning in a competitive business landscape.
• Continuous Improvement: Iterative development fosters a culture of continual improvement. At each iteration, teams review what worked and could be improved in processes, collaboration, and product quality.

Q45. What is the role of the Project Owner in Agile methodology, and how does effective communication with the team contribute to project success?

In Agile methodology, the Project owner determines business needs and priorities and communicates with a customer vision to a team. It makes communication effective in a team such that development should be according to customers’ requirements. This, in turn, enhances product quality, improved customer satisfaction, and successful project realization.

Q46. In the context of Agile development methodology, how do you integrate software testing techniques to ensure comprehensive test coverage?

Software testing should be integrated into all the activities necessary to implement Agile development methodology successfully. Next, test activity is tightly coupled with development iterations.

Teams can use strategies like TDD—where tests come before code, or BDD—focused on developer/non-developer collaboration—to ensure that "testing" is not a separate but intrinsic part of developing. Moreover, the routine tests are automated and can be executed very fast and repeatedly at every moment when the evolving codebase needs validations.

The company adopts a continuous testing and integration approach whereby software testing is not considered a standalone activity but a constant and parallel practice during the entire development cycle. This approach ensures a high level of thoroughness in testing, leading to the belief that what has been developed is a quality product.

Q47. Explain the Scrum cycle in Agile methodology and its role in achieving frequent deliveries of working software.

The Scrum cycle is an essential component of the Agile methodology, especially in relation to the Scrum framework. It comprises several important activities and roles that are interrelated to ensure frequent software releases in working conditions. The Scrum cycle includes the following elements:

Roles:

• Product Owner: Represents both stakeholders, incorporates product backlog and prioritizes work.
• 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?

A Professional Scrum Master ensures that there is an effective working of a team and Agile practices. Therefore, they act as coaches and guides who ensure that the team follows the Agile concepts. They are barrier removers who pave the way for Agile practices and enhance teamwork synergy. On the other hand, a great Scrum Master works to develop teams’ cohesiveness, providing a positive working environment, allowing continuous development, and making sure that everybody behaves according to Agile principles.

Q49. Explain how Agile methodology accommodates quick feedback and why this feature is essential for success.

Quick feedback is provided within the iterative and incremental nature of the agile methodology. It helps deliver working software increments with short development cycles, usually in time-boxed iterations or sprints. Using a frequent release cycle, various stakeholders, such as end-users and product owners, can quickly contribute their suggestions concerning the deliverables.

The quickness of review periods that include sprints and demo sessions facilitates the continual validation of a product in relation to changing needs. This becomes crucial for success as it ensures the development meets user expectations and business requirements.

The integration of immediate feedback helps resolve problems as they develop; it gives room for modification and enables consistent growth during product development. The iterative feedback loop constitutes a pillar for Agile's capability to provide practical, dynamic, and responsive high-quality, customer-oriented software.
