  • A user story is an agile software development/ project management tool that provides teams with simple, natural language explanations of one or more features of the project thats written from the perspective of the end-user.
  • The user story doesnt go into detail but only mentions how certain types of work will bring value to the end-user. The end-user, in this case, could be an external component or an internal customer/colleague within the organization.
  • They also form the building block of agile frameworks like epics and other initiatives.

    Explain Empirical Process Control In Scrum

    Empiricism is a very important term when discussing Scrum. It is defined as work thats based on facts, experiences, evidence, observations, and experimentation.

    Empiricism is used in Scrum to improve transparency by providing information about what has happened/happening within the team, as well as keeping track of progress and making any changes when require for observation purposes.

    Instead of relying on gut feeling or guesswork alone, empirical thinking improves with agile practices such as refactoring code in iterations for example.

    What Should Be The Ideal Length Of A Sprint

    The Sprint duration should be short enough in order to keep the team focused and also, to keep the business risk acceptable to the Product Owner. Ideally, the sprint length can be short enough to be able to synchronize the development work with other business events. The Scrum guide limits the Sprint length to 1 month but there is no official lower limit. So, 1 week can be often accepted as the shortest sprint duration. So, you can find the length that is best for your team in between 1 week – 1 month.

    What Is The Relationship Between User Stories Tasks And Epics

      Why the Interviewer Asks This Question

      This is a general knowledge question. Interviewers want to know if you can clearly articulate the relationships between user stories, tasks, and epics, as this is often knowledge a Scrum Master is called upon to teach. Scrum Masters are also responsible for ensuring Scrum principles are upheld when these concepts are applied to the product backlog or Scrum process management tools.

      What to Avoid

      Avoid using examples that are not simple or relatable. Some epics are unique to certain lines of business and may confuse the interviewer. For example, do not provide an example epic that is an acronym for a warehousing inventory control function to an interviewer who specializes in HR technology solutions.

    What Are The Sprint Burndown And Burnup Charts

    These charts help to keep track of the progress of the sprint. Burn up charts indicates the amount of work completed in the sprint and the burndown chart indicates the amount of work remaining in the sprint

    The Product Owner determines the amount of remaining work and compares it to the remaining work of the previous Sprints and forecasts the completion date of the project.

    In the Burn-Down chart, the vertical axis shows the amount of work , and the horizontal axis shows the amount of time passed from the beginning of the project or the number of Sprints passed.

    We usually add another line to present the uniform distribution of the volume of the work across the initially estimated number of sprints. This line acts as our planned progress and will be used to compare to our actual values.

    In the above chart, we can expect the project to be completed earlier than initially planned.

    In the Burn-Up chart, the vertical axis is the amount of work and is measured in units or story points, and the horizontal axis is time, usually measured in days.

    Each day you can see the amount of work completed and the total amount of work. The distance between the two lines is thus the amount of work remaining. When the two lines meet, the project will be complete. This is a powerful measure of how close you are to completion of the project.

    Bill Wake has given us the mnemonic INVEST which help us in writing a well-formed User Story.

    Splitting a story is not an easy task.

    What Is The Time Boxing Of A Scrum Process Called

    Time boxing concept is aligned to make best use of time and remove unwanted distractions by making the team more focused. It is like packing a suitcase where you have fixed amount of space and you try to fit in as much as possible or required for your travel.

    So in time boxing, the tasks are broken up in fixed sizes and team works on them. Since the time is fixed, so there is increased focus of the team to make the best use of time.

    To get the best value from time boxing, try to have a reasonable time box window that is neither too harsh nor too lenient.

      Avoid vague answers that do not describe the specific gaps the SAFe framework was meant to address. Enterprises rely heavily on concepts such as program management that are not addressed in Scrum. Interviewers want to ensure you understand how to manage a Scrum Team and deliver the necessary information to stakeholders outside of the Scrum Team.

    How Does The Agile Testing Methodology Differ From Other Testing Methodologies

    [ð??ð??ð??ð?? ð??ð??ð??ð??ð??] scrum master interview questions and answers â? agile interview questionsâ?[ð?·ð?¨ð?¹ð?»-1/4]

    Testers ensure that the whole process of testing is broken down into as small steps as possible, and just a small unit of code is tested in each of these steps. The team of testers consistently communicates the results of their work and changes the short-term strategy and even the development plan on the go, based on the results of the agile testing. The agile methodology encourages a flexible and rapid response to change, which leads to better end results.

    What Is Meant By Yesterdays Weather In An Agile Project

    Yesterdays weather was the word for Extreme Programming to keep teams from becoming too complacent during running and batting times.

    The story goes something like this. Once upon a time, a government spent a full amount of money on a satellite in the weather forecast. It took years. Million dollars cost. But in the end, they were able to launch a satellite that was able to accurately predict the weather at about 70% of the time. Not bad.

    It is then that one realizes that if they say that todays weather will be the same as yesterdays, they will be 70% accurate.

    XP uses this concept to keep teams from becoming too committed during sprints/iterations. It reminds us that the best prediction for the future is what we have done in the past.
