During a backlog grooming meeting, the team encounters a user story:
“As a parent, I want to view my energy usage, billing history, carbon footprint, and peer comparisons so that I can reduce my carbon footprint.”
The developers agree that this is an “Epic” and is far too large to fit into a standard two-week iteration. To make it actionable, they spend the meeting breaking it down into four separate, smaller stories that can be delivered incrementally.
Which backlog grooming activity does this scenario best represent?
a. Story Splitting.
b. Stakeholder Management.
c. Iteration Execution.
d. Scope Creep.

答案
a. Story Splitting.
正确。
理由
Story Splitting 指的是把一个过大、无法在单个迭代中完成的 Epic 或大型 User Story 拆分成多个更小、可独立完成和交付的故事。
题目中团队正是将一个大型 Epic 拆成 4 个较小的 stories，因此属于
Story Splitting
。
Question 2
According to the case study Agile Methodology — Incremental & Iterative Development: A Case Study, how might the team have gathered feedback during the iterative process?
a. Through regular demonstrations and reviews of working software increments.
b. By not involving stakeholders until the product was fully complete.
c. Through a single, final review at the end of the project.
d. By relying solely on the initial requirements document.

答案
a. Through regular demonstrations and reviews of working software increments.
Your Agile team plans a 2-week iteration where they release a functional subset of code (a working payment gateway) while simultaneously refining an existing recommendation algorithm based on data collected from the previous release.
Question: This team is combining both iterative and incremental strategies within the same development cycle.
True
False
中文：
此处有一段内容暂不支持显示。
答案
True
正确。
理由
这里同时出现了两种开发方式：
Incremental Development（增量式开发）
新增并交付一个之前没有的可工作功能：
Working payment gateway
也就是在现有产品基础上增加新的功能增量。
Iterative Development（迭代式开发）
根据之前发布后得到的数据继续改进已有功能：
Refining an existing recommendation algorithm
因此团队同时使用了 Incremental + Iterative Development。
Question 4
According to Making data mean more through storytelling | Ben Wellington | TEDxBroadway, what are some data storytelling guidelines?
a. No narratives, no insights, make it complex
b. Connect with People, Try to convey one idea, Keep it Simple, Explore the things you know best
c. Connect with People, convey many ideas, make it complex, Explore the things you know best
中文：
此处有一段内容暂不支持显示。
答案
b. Connect with People, Try to convey one idea, Keep it Simple, Explore the things you know best
正确。
理由
Ben Wellington 强调，好的 Data Storytelling 不应该只是堆积大量数据，而应该让数据能够被人理解和产生共鸣。
核心原则包括：
Connect with People — 与受众建立联系
Try to convey one idea — 尽量传达一个核心观点
Keep it Simple — 保持简单
Explore the things you know best — 从自己熟悉的领域进行探索
因此选项 b 正确。
Question 5
You are the project manager for a team developing a new mobile application.
The team has just completed their second iteration and while the project is moving well, you have received new feedback from stakeholders regarding a desired “social sharing” feature. Additionally, the developers have realised that some upcoming stories in the Product Backlog in LeanKit are too complex to be completed in a single iteration.
To address these changes and prepare for the next round of development, you facilitate a Backlog Grooming meeting.
During this meeting, which of the following activities should your team perform?
a. Clarifying ambiguities in stories to ensure they meet the “Definition of Ready” for planning.
b. Adding or removing user stories based on the new stakeholder feedback.
c. Splitting the overly complex “social sharing” story into smaller, more manageable tasks.
d. Re-evaluating effort estimates for tasks based on what the team learned in the previous iteration.
e. Updating existing stories with additional acceptance criteria or revised technical details.
f. Prioritising user stories to ensure the most valuable features are ready for the upcoming iterations.
According to the article What Is Iterative Design? 2026 Process & UX Examples, over-investing early on to create pixel-perfect prototypes is a recommended best practice during the initial cycles of iterative design.
