- Provide a comprehensive written description of the design decisions, challenges, and user interactivity goals in a DOC file.
- Analyze potential user scenarios and include explanations on how the dashboard meets these requirements.
Evaluation Criteria
Your submission will be evaluated on the creativity and utility of the dashboard design, the effectiveness of interactive elements, and the thoroughness of your documentation. Clarity, detail, and a user-centric approach are critical. The final DOC file should clearly articulate the process, design logic, and functionality of your interactive dashboard.
Objective
This task encourages you to combine all your acquired skills into an integrative reporting project that tells a coherent data story. The focus is on constructing a narrative through thoughtful visualizations that not only display data but also provide context and insights. You will integrate multiple data insights to form a comprehensive analysis narrative suitable for decision-making contexts.
Expected Deliverables
- A detailed DOC file explaining the narrative behind your data, including screenshots and explanations of each report section.
- A description of the integration process of various Power BI features such as calculated measures, interactive visuals, and storytelling techniques.
- A concluding section that summarizes key insights and suggests next steps or recommendations based on your analysis.
Key Steps to Complete the Task
- Select a publicly available dataset that offers a multi-dimensional perspective on the issue at hand.
- Create multiple report pages or sections that each focus on different aspects of the data analysis.
- Integrate interactive visualizations, calculated measures, and detailed annotations to build a compelling narrative.
