Top 10 agile interview Question and Answer Set 1

1. What is a Sprint Retrospective meeting?
 This is mostly the last part of the sprint or may be done after the sprint review meeting. Scrum master and the whole team participate in it, they discuss ‘ What went well’,’ What did not went well’ and ’ what needs to be improved’. It generally lasts for 2-3 hrs.



2. Is it ever suggested to use waterfall over Scrum? If yes, explain when?
 Yes, sometimes it is suggested to use the waterfall model over Scrum. It is done when the customer requirements are simple, well-defined, fully understood, predictable, and are not subjected to change until the completion of the project.



3. What is a Daily Stand-up Meeting?
 Daily Stand-up Meeting is a daily routine meeting. It brings everyone up to date on the information and helps the team to stay organized.
Each team member reports to the peers the following:
1. What did he/she did yesterday
2. What are the impediments faced
3. What he/she will do today

In general, it’s not a recorded meeting. Reporting will be between peers not to Scrum Master or Product Owner. It is normally timeboxed to a maximum of 15 minutes.
It is 15 Minute Stand-up Meeting.



4. What is the lifespan of the scrum cycle?
 The project size and team size are the two main factors which determine the time length of the scrum cycle. The size of a team can be 3 to 9 members. Usually, it can be estimated that the time span of a scrum sprint of about 3 to 4 weeks on an average.


5. What are the main roles in the scrum?
Scrum team: – Scrum team is made by an individual person who works collectively to achieve a particular task. The team works in a bond to deliver committed and requested product
Scrum master: – scrum master is responsible for the proper execution or working of the scrum team. Being a servant – leader and a coach, he ensures the proper productivity of a team towards scrum a sprint goal.

6. What are the places where Scrum and Kanban are used?
 When there is a need for shifting towards appropriate and prominent process then you use Scrum. When you need to improve the process that is running provided that there are not many changes then Kanban is used.



7. What does a scrum burndown chart comprise?
Answer: A scrum burndown chart should consist of
X-axis that displays working days
Y-axis that displays remaining effort
Ideal effort as a guideline
Real progress of the effort



8. What does the X and Y-axis of the burndown chart?
 In burn down, chart X-axis shows working days and Y-axis shows remaining efforts.
Project XYZ
Here, in the image blue line depicts the ideal time suggested for completing the project. For example in a project ideally, 28 tasks (efforts) are pending on the starting day of the project. And the project is scheduled to be completed in 20 days. So on the 20th day, zero tasks (efforts) should remain, which means the project should get completed.

On the other hand, the red line depicts the actual task (efforts) given with respect to the days. Here on day 5, 7 tasks need to be completed as per planning, however, in actual only 4 tasks were completed.
Thus, it provides proper tracking down of the progress of the project and thereby helps in improving the efficiency and on-time taken to deliver the project.



9. What are the artifacts of Scrum process?
Sprint backlog – The Sprint Backlog is the set of Product Backlog items selected for the Sprint, plus a plan for delivering the product Increment and realizing the Sprint Goal. The Sprint Backlog is a forecast by the Development Team about what functionality will be in the next Increment and the work needed to deliver that functionality into a “Done” Increment.
Product backlog – The Product Backlog is an ordered list of everything that might be needed in the product and is the single source of requirements for any changes to be made to the product. The Product Owner is responsible for the Product Backlog, including its content, availability, and ordering.
Velocity chart- A velocity chart shows the sum of estimates of the work delivered across all iterations. Typically, velocity will stabilize through the life of a project unless the project team make-up varies widely or the length of the iteration changes.
Burn-down chart – It is a chart that shows how quickly you and your team are burning through your customer’s user stories. It shows the total effort against the amount of work we deliver on each iteration.



10. What do you mean by the disadvantages of the agile model?
 There are certain disadvantages of the agile system which are discussed below.
It is not easy to predict. If a big project is assigned you will have a problem to estimate the effort you need to put into that.
Focusing on design and documentation is not always proper.
The final product will not satisfy the customers if the guidelines given by the client are not properly understood.
The high-level decision making is in the hands of the higher authorities which makes the fresher to have little knowledge.
