Use a Radar Chart When One Average Score Hides Where the Options Actually Differ

An average score is tidy, but it often hides the actual tradeoff. Two vendors can both score 78 while one is strong on speed and support and the other is strong on cost and integration. A team member can look balanced overall while still having one obvious development gap. A radar chart is useful when the shape of the strengths matters more than one summary number.

Where a radar chart earns its keep

• Comparing candidates across skills where no single metric should dominate the decision.
• Reviewing product options across usability, cost, reliability, support, and implementation effort.
• Showing how a team, region, or business unit differs across the same repeated scorecard dimensions.
• Presenting before-and-after capability profiles where the pattern of change matters as much as the total.

What a radar chart shows better than a table

A table is still better for exact values, but the radar shape answers a different question: where does each option bulge outward or collapse inward? That makes imbalance visible quickly, which is often the real decision input when people are choosing between several imperfect options.

How to keep the chart honest

• Use the same scale on every axis so one dimension is not visually overstated.
• Keep the number of axes modest; if you need fifteen dimensions, a table or bar chart may be clearer.
• Label each axis with a criterion people already understand rather than internal shorthand.
• Do not pretend the chart gives statistical precision. It is for comparison and discussion, not for replacing the raw score table.
