Technical requirements

  • Build your report using only Power BI
  • The number of pages in the report is not limited
  • At least one report page has to contain a minimum of 2 ZoomCharts Drill Down Visuals. See a practical guide on Drill Down Visuals here

What should your report include?

Create a report that allows end users to easily find answers to the following questions: 

  • What is the relationship between product ratings and recommendation status?
  • Which brands have the highest average customer satisfaction, and how does it vary across different product categories?
  • How do product features (like color or dimensions) influence reviews and ratings?

Judging criteria

Business users use reports to make data-driven decisions. That’s why reports are called effective if they enable users to drill down and filter data quickly and intuitively to find answers to any question they might have and analyze data in all possible directions and dimensions. We will evaluate:

  1. How easy is it to understand the data? (max 10 points)
    • Is too much text used for explanation?
    • Are the indicative colors in charts instinctually understandable?
    • Does it tell a story?
  2. How easy-to-use is the report? (max 14 points)
    • Cross-chart filtering implementation across the report. Can other visuals provide relevant data as the user explores the report?
    • Response time
    • Drill Down: multi-layer data exploration. Can the user drill down and gain additional insights within the report?
    • Use of tutorial overlays and other elements to assist new users. Can a new user start using this report straight away with just the guidance provided within the report itself?
  3. How good is the report design and is it suitable for its purpose? (max 10 points)
    • Visual design: is the overall look consistent, no empty spaces, no overcrowding?
    • Interface design: are there unnecessary visualizations/buttons/complexity in use?
    • UX design: is the produced report usable?
    • Report design: is the main challenge answered?
    • Technical: are all the fonts used the same, are the sizes readable?

You are encouraged to use various techniques at your disposal, such as tooltips, drill-throughs, drill-downs, cross-chart filtering and page navigation features, to enhance your analysis.
