How We Score Your Work

Our AI reviewer evaluates every submission across four dimensions:

1-5

Storytelling

Does your visualisation tell a clear, compelling story? We look for logical flow, context, and narrative progression that guides the viewer through your insights.

1-5

Design

Is your dashboard clean, readable, and visually appealing? We evaluate layout, typography, colour choices, and visual hierarchy.

1-5

Technical

Does your work demonstrate strong technical skills? We assess DAX usage, data modelling, chart type selection, and interactivity implementation.

1-5

Insights

Do you provide meaningful analysis? We look for non-obvious discoveries, actionable recommendations, and demonstrated business impact.

A score of 3 represents solid, competent work. Scores of 4-5 require exceptional evidence in that dimension.

Digital-first banks operating across multiple customer segments and transaction channels face a range of operational, financial, and risk-related challenges, and this dataset highlights several critical areas:

Operational & Analytical Challenges

  • Fragmented visibility across customers, transaction types, channels, and merchant categories makes it difficult to understand overall transaction health.
  • Variations in customer behaviour across segments (Starter, Standard, Premium, Business) obscure which groups drive value and which contribute disproportionate risk.
  • Fraud exposure is distributed across channels, merchant categories, and regions, making emerging threats difficult to detect without structured analysis.
  • Transaction failures (Declined and Reversed transactions) can occur for multiple reasons, limiting visibility into operational bottlenecks and customer friction.
  • Fee revenue is generated across different transaction types and channels, making it challenging to identify revenue drivers and potential leakage.
  • Differences in customer verification status (KYC vs non-KYC) create uneven risk profiles that are difficult to monitor without detailed segmentation.
  • High transaction volume does not always translate into high profitability, masking inefficiencies in fee structures and customer value.
  • Limited visibility into merchant category performance makes it difficult to align risk classifications with actual fraud activity.
  • Lack of clear linkage between customer behaviour, transaction outcomes, and fee generation weakens decision-making across Risk, Product, and Finance teams.
  • Cross-dimensional interactions (e.g., customer segment × channel × merchant category × region) are complex and often under-analysed, hiding opportunities for risk reduction and revenue optimisation.
  • Potential fraudulent activity, transaction anomalies, and fee inconsistencies introduce financial, operational, and compliance risks.
  • Difficulty connecting transaction activity to business outcomes such as revenue growth, fraud prevention, operational efficiency, and customer experience limits strategic decision-making.

Judging Criteria for Power BI Reports

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.
