Common dashboard mistakes and how to fix them

Home / Everything About / Everything About Analytics / Common dashboard mistakes and how to fix them

Dashboard mistake one: too many metrics.

Dashboard shows fifty metrics. Stakeholder is overwhelmed. Reads nothing. Makes no decisions.

Dashboard is built but nobody uses it. Failure.

Fix: cut to ten metrics. Prioritize metrics that drive decisions. Metrics that are interesting but not actionable get removed. Metrics that support other metrics get relegated to supporting dashboards. Primary dashboard shows five to ten. Supporting dashboards show detail.

Mistake one: too many metrics

Fifty metrics overwhelm reader. Reader cannot process. Reads nothing. Makes no decision.

Fix: cut to five to ten metrics. Cut metrics that do not drive decisions. Keep metrics that answer: should I spend money here. Should I hire here. Should I change product here.

Mistake two: no baseline for comparison

Metric shows revenue is five hundred thousand. Is that good. Reader has no idea. No context.

Fix: always show baseline. This month compared to last month. This month compared to same month last year. Comparison to goal. Pick two baselines. Too many baselines creates confusion.

Mistake three: no status indicators

Metric shows conversion rate is three percent. Reader thinks: is that good. Needs to know target.

Fix: add color. Green if at or above target. Yellow if slightly below. Red if significantly below. Color removes ambiguity. Reader scans colors, finds problems instantly.

Mistake four: metrics without explanation

Metric shows traffic up thirty percent. Reader thinks: why. Does not know. Cannot decide whether good or bad.

Fix: add brief explanation. Traffic up thirty percent from new paid search campaign launched Tuesday. Campaign is tracking at two point five x ROAS. Explanation tells reader why metric moved and what to do.

Mistake five: no action clarity

Metric shows problem. Red indicator shows something is wrong. But reader does not know what to do.

Fix: add action item. Error rate is two percent (target one percent). Action: investigate payment processor latency. Assigned to ops. Due Friday. Action item tells reader what to do.

Mistake six: inaccurate data

Dashboard shows email channel generated one hundred thousand revenue. Actual was fifty thousand (data error). Company makes decision based on wrong number. Doubles email budget. Wastes fifty thousand dollars.

Fix: audit data monthly. Compare dashboard data to source system. Fix discrepancies. Validate numbers before displaying. One hour of validation prevents one hundred thousand dollar mistake.

Mistake seven: metrics that do not matter

Dashboard shows page views (vanity metric). Page views are interesting but do not drive decisions. Should be cut.

Fix: only show metrics that drive decisions. Metric should answer: should I spend money here. Should I hire here. Should I change product here. If metric cannot answer those questions, cut it. Vanity metrics go to supporting dashboard if anyone cares.

Mistake eight: outdated data

Dashboard updated yesterday but new data arrived overnight. Dashboard shows yesterday's numbers. Decision is made on stale data. Decision is wrong.

Fix: set update frequency to match decision frequency. If decisions happen daily, update dashboard hourly or near-real-time. If decisions happen weekly, update daily. If decisions happen monthly, update weekly. Align refresh to decision cadence.

Mistake nine: beautiful but incomprehensible

Dashboard has fancy charts, lots of colors, looks amazing. But reader cannot understand what it shows.

Fix: simplify visuals. Make numbers large. Make colors meaningful (not decorative). Make labels clear. Clarity over beauty. Beautiful dashboard that confuses reader is useless. Simple dashboard that clarifies metrics is valuable.

Mistake ten: no documentation

Metric shows revenue. Reader does not know: does this include refunds. Does this include pending transactions. Does this include subscription vs one-time. Metric is ambiguous.

Fix: document metric. Revenue includes completed transactions in last thirty days. Excludes refunds. Includes subscription and one-time sales. Excludes pending transactions (not yet processed). Documentation removes ambiguity.

Real example: fixing a broken dashboard

Company has dashboard with fifty metrics. Team ignores it. Dashboard is not used.

Audit reveals

Metrics are confusing (no baseline). Data is inaccurate (revenue discrepancy of ten percent). Metrics do not drive decisions (includes vanity metrics like page views).

Redesign

Step one: identify metrics that drive decisions. Revenue, conversion rate, customer acquisition cost, churn, feature adoption, system uptime, customer support response time. Cut everything else.

Step two: add baselines. Each metric shows: actual, last month, last year, goal, trend.

Step three: add status colors. Green/yellow/red based on goal.

Step four: add explanations. Why did metric move. What action is needed.

Step five: audit data. Pull dashboard numbers, compare to source systems. Find errors. Fix errors.

Step six: update daily at 6am. Dashboard refreshes with previous day's data before team standup.

Result

Team uses dashboard. Team sees at a glance which metrics are healthy and which need attention. Team makes decisions based on dashboard. Mistakes are caught and fixed faster.

Cost of fix: one week of redesign and data audit. Benefit: faster decision-making, fewer wrong decisions, more consistent strategy.
