Categories Maturity Evaluation

For the evaluation of the maturity level of the category, the following formula is applied:

Category maturity level = floor ( ( Q1(score) + … + Qn(score) ) / n )

Where n is the number of questions in the category.

List of categories

The following categories are recognized as part of the PKI maturity assessment:

#CategoryDescriptionInputs and evidence

Q1(score) = 3, Q2(score) = 4, Q3(score) = 1, Q4(score) = 5, Q5(score) = 5

Category maturity level = floor(3+4+1+5+5) / 5 = floor(3,6) = 3 (Advanced)
