What is Qualitative?

Understanding Qualitative

Measuring something without using numbers, using adjectives, scales, grades, etc. Qualitative risk assessment uses subjective attributes rather than precise numerical measurements to evaluate risk factors, often employing descriptive categories such as High/Medium/Low or rating scales. This approach is useful when exact data is unavailable or when expert judgment provides valuable context that numbers alone cannot capture. Qualitative assessment methods are described in standards like NIST SP 800-30, ISO 27005, and FAIR. Organizations implement qualitative analysis through risk matrices, scenario evaluations, expert interviews, and consensus-based assessments. For example, a healthcare organization might conduct a qualitative risk assessment of its telehealth platform using subject matter expert interviews to categorize threats as High/Medium/Low based on likelihood and impact, facilitating prioritization despite the absence of precise frequency and loss data.
