Competency gap on dimension j: Gap_j = Target_j - Current_j. Overall rubric alignment: Alignment% = (sum(min(Current_j, Target_j)) / sum(Target_j)) * 100%.
Chart Design & Use-Case Tips
- 01Competency gap on dimension j: Gap_j = Target_j - Current_j. Overall rubric alignment: Alignment% = (sum(min(Current_j, Target_j)) / sum(Target_j)) * 100%.
- 02Plot Current Assessment in Series A and Target Level Rubric in Series B to immediately highlight where the employee exceeds expectations vs. where coaching is needed.
- 03Use a consistent 0–100 or 1–5 scale across all axes during biannual performance and promotion calibrations.
- 04Export as PNG or PDF to attach directly to career growth plans.
Frequently Asked Questions
How many skill dimensions work best on a competency radar?+
Six to eight balanced pillars (mixing technical execution, architecture, operational rigor, and collaboration) create the clearest spider polygon.
Can I compare three candidates or team averages at once?+
Yes, populate Series C in the Data Workbench to overlay a third profile on the radar grid.
What does a balanced vs. spiky radar polygon signify?+
A broad rounded polygon indicates a well-rounded generalist or staff lead, while a sharp spike shows deep specialist expertise in one domain.
