Common Dashboard Mistakes

Dashboard anti-patterns:

  • Too many metrics: If everything is important, nothing is.
  • Vanity metrics: Numbers that look good but don't drive decisions.
  • No context: A number without comparison (target, trend, benchmark) is meaningless.
  • Chart overload: Complex visualisations that require interpretation training.
  • Stale data: Data that's too old to be actionable.
  • No drill-down: Cannot investigate when something looks wrong.

Selecting the Right KPIs

Start With Objectives

KPIs should connect to strategic objectives. If you can't explain how a metric supports a business goal, question whether it belongs on the dashboard.

Good KPIs Are

  • Actionable: When the metric moves, you know what to do
  • Measurable: Clearly defined and consistently calculated
  • Timely: Available frequently enough to act on
  • Owned: Someone is accountable for the metric
  • Leading: Indicators of future performance, not just past

Less Is More

An executive dashboard should have 5-7 KPIs. A department dashboard, 8-12. If you can't see the full picture at a glance, you have too much. Push detail to drill-down views.

Balance the Portfolio

Include a mix of metric types:

  • Financial and non-financial
  • Leading and lagging indicators
  • Internal and external perspectives

Design Principles

Provide Context

Never show a number alone. Always include comparison:

  • vs. target or budget
  • vs. prior period (last month, last year)
  • vs. trend (is it improving or declining?)

Make Status Obvious

Use colour coding (red/amber/green) so viewers can assess status in seconds. Define thresholds clearly - what level triggers red?

Choose Appropriate Charts

  • Big numbers: Best for single most important metrics
  • Line charts: Trends over time
  • Bar charts: Comparisons between categories
  • Gauges: Progress toward a target (use sparingly)
  • Tables: When precise numbers matter

Avoid Chart Junk

Remove unnecessary elements: 3D effects, heavy gridlines, decorative imagery. Every element should help understanding, not distract from it.

Logical Layout

Group related metrics. Place most important items top-left (where eyes start). Create visual hierarchy through size and position.

Data Freshness

Dashboard refresh frequency should match decision frequency:

  • Operational dashboards: Real-time or near-real-time
  • Tactical dashboards: Daily
  • Strategic dashboards: Weekly or monthly

Always show when data was last updated. Stale data without acknowledgment destroys trust.

Drill-Down Capability

Dashboards answer "what's happening?" Drill-down capability answers "why?" Every dashboard should enable investigation:

  • Click on a metric to see detail breakdown
  • Filter by time period, region, segment
  • Navigate to detailed reports
  • Export data for further analysis

Driving Dashboard Adoption

Involve Users Early

Co-design with the people who will use the dashboard. They know what decisions they make and what information they need.

Embed in Routines

Review dashboards in regular meetings. Start standups with dashboard review. Make checking the dashboard part of daily workflow.

Iterate Based on Use

Track which metrics people actually look at. Remove unused metrics; enhance useful ones. Dashboards should evolve with changing business needs.

Summary

Effective dashboards are focused, contextual, and actionable. Select KPIs that connect to strategic objectives. Provide context through targets and trends. Design for at-a-glance comprehension. Enable drill-down for investigation. Iterate based on actual use.

The test of a good dashboard: does it change behaviour? If people make different (better) decisions because of what they see, the dashboard is working. If it's just background noise, redesign it.

Key takeaways

  • Most dashboards fail because they show data instead of driving decisions.
  • Limit each dashboard to 5–7 KPIs that directly connect to actions someone can take.
  • Design for scanning: the most important metric should be visible in 3 seconds.
  • Dashboard adoption depends on trust in the data. Invest in data quality first.

Meet the person

Written by the person who does the work

This article comes from real projects. If it raises a question about your own system, you can ask the founder directly.

HELLO PEOPLE designs, builds and looks after AI, software, app and data solutions for Australian businesses, with senior expertise on every project and a scope agreed before work starts. For an older system, that means learning what it really does first, so nothing your business relies on is lost.

Since 2007, HELLO PEOPLE has delivered more than 100 projects from Perth for small and medium businesses across Australia: custom software and apps, system integrations, data migrations, reporting and dashboards, and AI that works inside the systems a business already runs.

I lead every engagement myself. I trained in accounting before moving into IT, hold accounting and IT professional qualifications and an MBA, and bring more than 20 years of experience across sales, service delivery, inventory and compliance. I am also a PhD candidate in AI at Curtin University, researching retrieval-augmented generation (RAG), so the technology is always judged by what it does for the business.

  • An old-fashioned service

    Small and boutique. The person who scopes the work is the person who does it, and the same person is there when the old system is switched off.

  • Quick responses

    No ticket queue and no account manager in between. You hear back within one business day, usually sooner.

  • A long-term partner

    The upgrade is the start, not the end. When you need the next system, integration or report, you call the same person, who already knows your business.
