Integration

5 minutes 5 Questions

Integration is a crucial concept in creating a potentially releasable Product Increment. It refers to combining all the Product Backlog Items integrated during the Sprint into a coherent whole. It is not just about merging code in software development, but about making all parts work together. This…

Guide: Integration in Product Increment Scrum

The term 'Integration' refers to the process of combining various system components or subsystems into a single coordinated entity. In the context of Scrum, more specifically Product Increments, 'Integration' is the consolidation of all product backlog items completed during a Sprint and the value they produce, merged into a functioning whole.

Importance of Integration:
Integration plays a crucial role in Scrum. It allows for continuous progress monitoring, helps identify issues and barriers, and facilitates their resolution at an earlier stage. It ensures continuous flow and cohesion throughout the Sprint, fostering transparency and flexibility.

How it works:
Once particular backlog items are defined, developed, and tested during a Sprint, they are integrated to form a potentially shippable product increment. This integration allows teams to continually iterate and evolve the product in alignment with customer needs and feedback.

Exam Tips: Answering Questions on Integration:

Understand the basics: Know what Integration is, why it is vital, and how it works in Scrum.
Key Terms: Understand terms like 'Product Increment', 'Backlog Items' and 'Sprint' thoroughly.
Practical Understanding: Try to apply the theoretical principles of Integration in Scrum to practical examples. This can make it easier to understand questions and provide accurate answers.

Remember, thorough preparation and understanding of the core principles of Integration in Scrum are essential to answering exam questions.

PSM I - Integration Example Questions

Test your knowledge of Integration

Question 1

Scenario: You are the Scrum Master of a team developing an e-commerce platform. It plans to integrate with a popular payment gateway. During the Sprint Planning, the team realizes that integration would be more complex than anticipated. How could this situation have been forestalled?

The team should increase the duration of the sprint to accommodate the additional work required for the integration. The development team could have divided the integration task into smaller, manageable tasks to make them seem less complex, focusing on integrating basic functionality first and enhancing features in subsequent sprints. This incremental approach, though seemingly effective, might not fully address the underestimation of complexity. The Product Owner should reallocate resources to ensure that the integration is prioritized over other functionalities. The team should have engaged in more thorough backlog refinement to better understand the requirements and complexities.

Correct Answer: The team should have engaged in more thorough backlog refinement to better understand the requirements and complexities.

While increasing the sprint duration might seem like a solution, it goes against the Scrum principle of maintaining consistent sprint lengths to ensure predictability and improve estimation. Reallocating resources or priorities by the Product Owner without full team consensus can impact team morale and disrupt the sprint goal. Dividing the task into smaller parts may aid in managing work but doesn't prevent the initial underestimation of complexity. Proper backlog refinement activities enable the team to understand and discuss complexities, dependencies, and effort involved in implementing new features or integrations, hence it is the correct approach to forestall such situations.

Question 2

Scenario: As a Scrum Master for a mobile app development project, your team has successfully integrated a new feature in the latest sprint. However, negative user feedback starts pouring in after a few days of the feature release. What would be the best course of action here?

Review the feedback during the Sprint Retrospective and adjust the Product Backlog if necessary Compile all user feedback and prioritize it for discussion in the next Daily Scrum meeting for immediate action Immediately start a new sprint focusing solely on the negative feedback Assess the feedback independently before sharing it with the development team to avoid overwhelming them

Correct Answer: Review the feedback during the Sprint Retrospective and adjust the Product Backlog if necessary

The correct approach involves reviewing the feedback during the Sprint Retrospective, where the team can discuss what went well, what didn't, and how they can improve, including integrating user feedback into future sprints if necessary. Starting a new sprint based solely on the feedback, assessing feedback without team involvement, or prioritizing immediate action without team discussion and agreement on the proper course of action does not align with Scrum values and principles. The focus should always be on team collaboration, openness, and adapting to change after careful consideration and planning.

Question 3

Scenario: Your team works on a Scrum project which includes the incorporation of a cutting-edge machine learning model. A few days later, the team discovers that the model is not producing anticipated results. What could be the possible issue?

The Product Backlog items related to the machine learning model might not have been sufficiently clear, detailed, or understood by the entire Scrum Team, leading to misinterpretations in implementation. The refinement of the Sprint Backlog was not effectively done, leading to a disconnect between the planned work and the team’s progress. Since integrating cutting-edge technology requires continuous learning and adaptation, it's possible that the team's velocity is impacted due to the steep learning curve. The Development Team's failure to regularly update the Scrum artifacts, including the Sprint Backlog and Increment, may have led to a lack of transparency and misalignment with the Sprint Goals.

Correct Answer: The Product Backlog items related to the machine learning model might not have been sufficiently clear, detailed, or understood by the entire Scrum Team, leading to misinterpretations in implementation.

In Scrum, it's essential for the Product Backlog to be well-defined, clear, and understood by both the Development Team and stakeholders to ensure that the work being undertaken is aligned with the product vision and goals. Poorly defined Product Backlog items can lead to confusion, misinterpretation, and ultimately, a product increment that does not meet expectations. The wrong answers, while plausible issues in a Scrum project, don't directly impact the functionality of a specific deliverable as much as an inadequately prepared Product Backlog would.
