OPTIONAL!
This last milestone is strictly optional. Should you decide to complete it, its score will replace the lowest milestone score you have received this semester. If you score lower on this milestone than any other milestone, it will have no effect.
Maintaining Existing Infrastructure
Remember that all business decisions should be compounding over the semester, and thus that you should ensure that all existing dashboards for past milestones remain functional and accurate to the data at hand. This may be as simple as not touching what was done before, and everything still works. But if you need to make architectural changes (which should be documented with an ADR!), it may require revisiting older milestones to ensure they still operate correctly. In general, you should plan on each business decision mapping to a single dashboard. You could reuse components of existing dashboards, but it should be clear in Grafana what business decision each dashboard maps to. Keep in mind that for these assessments, what matters is the accuracy and degree to which the provided dashboard helps inform the business decision. The technical means by which you compiled and created that dashboard is not considered here, but should be included in your documentation.
The Business Question
For this optional sixth milestone, the Blue line is finally active!
After months of anticipation, Prague’s metro system has finally activated a long-delayed new line—a north–south connector designed to ease congestion in the central-south region and improve service to several underserved neighborhoods south of downtown. With the line now operational, city planners are eager to understand its real impact: Has it successfully redistributed ridership across the network? Are certain stations now seeing reduced congestion or shorter wait times? Have travel patterns shifted in ways that suggest a broader change in commuter behavior? By comparing station congestion and wait-time metrics from before and after the line’s opening, officials hope to evaluate the effectiveness of the expansion and identify any unintended consequences elsewhere in the system.
Assessment
You will be assessed on the following for each dashboard/business decision:
| Category | 4 – Exemplary | 3 – Proficient | 2 – Developing | 1 – Insufficient |
|---|---|---|---|---|
| Relevance to Business Question | Dashboard clearly and directly answers the question; all content is purposeful. | Dashboard mostly answers the question; minor gaps or tangents present. | Partially answers the question; some visuals are only loosely related. | Does not address the business question meaningfully. |
| Analytical Insight and Context | Provides thoughtful analysis and useful context; insights go beyond surface-level. | Provides some interpretation or context; insight is basic but present. | Interpretation is minimal; context is unclear or overly simplistic. | No analysis or meaningful interpretation provided. |
| Accuracy and Reproducibility | Data is accurate and internally consistent; results could be closely replicated. | Minor inaccuracies or unclear methods; mostly consistent and plausible. | Not clearly reproducible; errors or inconsistencies raise concerns. | Major inaccuracies or contradictions; cannot be trusted. |
| Design and Aesthetics | Visually appealing and easy to interpret; layout, labels, and colors enhance clarity. | Clear design with minor layout or labeling issues. | Layout or chart choices hinder interpretation; lacks polish. | Poorly designed; unclear or disorganized layout and labels. |
| Communication and Presentation | Titles, captions, and text are clear, professional, and aid interpretation. | Generally well-communicated; minor missing or unclear text elements. | Explanations are vague, sparse, or unhelpful. | No explanations or guiding text; confusing to the intended audience. |
