User Stories

User-focused software development approach.

User stories are one of the core components of Agile methodologies. These are informal descriptions of a software feature, told from the end-user's perspective. They help to create a simplified description of a requirement and focus on the value provided to users.

Question 1

Steve, a Product Owner at an e-learning company, is developing a persona named 'Busy Professional' for their language learning app. What should Steve ideally focus on while catering to this persona?

Correct Answer: Short, efficient lessons that can be completed during breaks at work.

When creating a persona named 'Busy Professional' for a language learning app, Steve, the Product Owner, should ideally focus on providing short, efficient lessons that can be completed during breaks at work. As the persona suggests, 'busy professionals' generally don't have a lot of spare time, and therefore, learning modules that are concise, efficient, and can be done in short periods would be most suitable. Offering a feature to share their progress on social media platforms is not directly related to their learning needs and can be viewed as an extra feature. Assistance for planning weekend trips and help in arranging a music playlist to study are completely outside the scope of a language learning app and might not align with the immediate learning needs of a busy professional.

Question 2

A team member is continuously arguing against a criterion in the Definition of Done believing it to be unnecessary. The rest of the team agrees with the criterion. As a Scrum Master, what will you recommend?

Correct Answer: Meet with the team member to understand their concerns and clarify the importance of the criteria agreed upon by the rest of the team.

The scrum master is a facilitator who helps the team understand and implement the principles of the scrum framework. In this situation, when a team member disagrees with a criterion in the Definition of Done (DoD), the scrum master has to ensure every team member's perspective is heard. So, the correct course of action is to meet with the team member to understand their concerns and clarify the importance of the criterion agreed upon by the rest of the team. The other answers aren't appropriate responses to this situation. Ignoring the team member's insistence and moving forward with the agreed DoD, asking the team to immediately vote on whether to keep or remove the criterion from the DoD, or changing the DoD based on the team member's disagreement without discussing with the entire team don't build agreement, empower the team member, or drive a mutual understanding of the DoD standards.

Question 3

You are working on a medical app which will provide periodical health summaries to users. The summaries would be based on data like sleep patterns, heartbeat, etc. How should the acceptance criteria be written for this feature?

Correct Answer: The system collates user health data over a defined period, generates a health summary, and delivers it to the user via the app.

The best answer will be: 'The system collates user health data over a defined period, generates a health summary, and delivers it to the user via the app.' This approach ensures the reliability and validity of the health summaries as it uses defined health parameters and collates them over a specific period. The answer aligns with Agile principles, making it suitable for the PMI-ACP course. - The answer 'The system generates health summaries regardless of available data. ' is not acceptable as the health summaries should be based on comprehensive and accurate health data. - The answer 'The system uses any random user data to generate health summaries.' is incorrect as using random data fails to guarantee accurate health summaries. Real-time user data is essential for producing reliable health reports. - The final answer 'The system collects data but fails to generate a health summary.' is clearly incorrect, as the main feature of the app would be to generate health summaries based on gathered data.
