The Result at a Glance:

PROBLEM

Dashboard had 40+ metrics but no clear answers

ROOT CAUSE

Reporting organized around available data, not business questions

SOLUTION

Restructured around 5 core KPIs tied to 3 business questions

OUTCOME

Stakeholders moved from reviewing data to making decisions. Dashboard adoption increased and manual reporting time decreased significantly.

Project Scope & Contribution:
MY ROLE

Analytics / Data Visualization

SCOPE

Stakeholder interviews → KPI definition → dashboard architecture → build → insights

01

Stakeholder Context

The existing dashboard suite contained over 40 metrics across multiple pages. Stakeholders opened it weekly but could not consistently identify what was improving, declining, or requiring action. The dashboard was comprehensive but not actionable.

02

Business Questions

I interviewed stakeholders to identify the actual questions they needed answered:

  • Are conversions declining, and if so, where in the funnel?
  • Which channels are driving qualified revenue vs. low-quality traffic?
  • Where is the funnel weakening this week compared to last week?
03

KPI Definition

I created a KPI dictionary defining exactly how each metric is calculated, what data source it uses, and what constitutes a meaningful change:

KPI Definition Source Review Cadence
Conversion Rate Purchases / Sessions GA4 Weekly
Revenue Sum of purchase_revenue GA4 + Shopify Daily
Blended ROAS Revenue / Total Ad Spend Ads + GA4 Weekly
CAC Ad Spend / New Customers Ads + CRM Monthly
Funnel Drop-off Step N / Step N-1 GA4 Weekly
04

Dashboard Architecture

I structured the dashboard in layers of detail:

Executive — 5 KPIs with week-over-week trend
Channel — Performance by acquisition source
Funnel — Step-by-step conversion analysis
Product — Top products, categories, AOV
Detail — Drill-down for investigation
05

Analytical Findings

The restructured dashboard immediately revealed patterns that were invisible in the old format. Conversion trends were visible by segment, not just in aggregate. Channel performance was comparable side-by-side. Funnel weaknesses were identifiable by step and by device.

06

Recommendations

Based on the dashboard redesign process, I recommended:

  • Start every dashboard with the 3 questions it answers — not the data it contains
  • Define KPIs before building any visualization
  • Use consistent date ranges and comparison periods across all pages
  • Add written commentary to weekly reports — charts alone don't explain "so what?"
07

Before / After

The transformation reduced cognitive load while increasing analytical depth. Stakeholders spent less time searching for information and more time acting on insights.

Dimension Before After
Metrics displayed 40+ 5 core KPIs + drill-down
Time to find answer Minutes of searching Visible on first page
Decision clarity Ambiguous Clear action signals
Dashboard adoption Opened but rarely used Referenced in weekly meetings
08

Outcome

The redesigned dashboard became the single reference point for weekly performance reviews. Stakeholders transitioned from reviewing numbers to making decisions.
