Context & Problem

I have built dashboards that people treated like gospel. I built the India FinTech dashboard to map $15B+ across years. I built Shark Catalyst to test myths with SQL and statistics, analyzing 250Cr+ investments across 4 seasons. Both projects taught me that a chart is a tool not a verdict. People interpret charts through bias, goals and pressure. The same visualization can cause investment or cause dismissal. That gap between data and decision is where most products fail.

Process & Examples

When I built the FinTech dashboard I focused on accuracy. I cleaned thousands of rows and created 9 DAX metrics for analyst use. Analysts still came to different conclusions from the same dashboard. Why? Because they started with different questions and different incentives. One team looked for growth signals. Another looked for concentration risk. The visualization did not change. The narrative did.

With Shark Catalyst I tried a different approach. I paired every chart with the SQL query that produced it and a one line verdict that stated the hypothesis the chart tested. That reduced argument time in meetings. People stopped arguing about the numbers and started arguing about implications. If the data supports a claim state the assumptions, show the p-value and move on. If not, show the effect size and explain the operational impact. That small change made meetings shorter and decisions faster.

Design Rules I Follow

Make the question explicit at top of each view. The human viewer must know what decision this chart is intended to inform.
Show the data lineage and one sentence method note. If a KPI uses a specific filter or approximation show it. That avoids surprises.
Offer the binary fast path and the slow path. The fast path is a single sentence verdict for a leader. The slow path links to the SQL and the full table for analysts.
Surface uncertainty. Show confidence intervals, sample sizes and p values when you test a hypothesis. People trust numbers less when they are hidden.

Tools & Execution

I use Power BI and Plotly for visuals and SQL backed views for truth. For Shark Catalyst every chart links to the underlying SQL snippet. For the FinTech dashboard I added a small KPI card that shows sample size and data coverage. For North Star, I modeled behavioral signals so product nudges match the data pattern. The toolchain is secondary. The primary design work is choosing what question the dashboard answers.

What Leaders Should Care About

Dashboards built with human context produce measurable outcomes. In my work the change was operational. Meetings that used the Shark Catalyst views reduced churn in decision threads and shortened time to decision. The FinTech dashboard turned ad hoc requests into repeatable analysis. Those are the outputs leaders value. They want fewer ambiguous discussions and faster execution.

Practical Checklist you can Apply

• Add a one line question above each chart.

• Add a one sentence verdict for leaders with a link to the data.

• Display sample size and a simple uncertainty mark.

• Design a fast path and a slow path in each dashboard view.

Outcome & Impact Summary

Shark Catalyst became an evidence tool not a conversation pit. The FinTech dashboard moved analysis from manual spreadsheet reports into a repeatable Power BI process. Both products show a single truth. A visualization without human context is just a prompt for argument. With context it becomes a lever for action.
