Combining checklist items into a single score often destroys valuable information.
A profile shows performance on each dimension separately. A score collapses everything into one number.
Profiles reveal strengths and weaknesses. They show where improvement is needed. A single score of 7/10 tells you nothing about what's working or what needs attention.
For improvement purposes, profiling is almost always superior. You can see exactly which areas need work.
Only combine scores into rankings when you absolutely must choose between alternatives and cannot avoid it.
When you do need an overall score, be very cautious about weighting. Equal weighting is often the most defensible approach, despite its limitations.
