Final answer:
A truly quantitative risk analysis is difficult to achieve due to limitations in observing internal thought processes, difficulty in parameterizing and analyzing risks, and software and hardware limitations.
Step-by-step explanation:
A truly quantitative risk analysis is difficult to achieve due to several limitations. First, some internal thought processes and personal explanations are impossible to observe directly and can only be conveyed qualitatively through words. This makes it challenging to organize and tabulate the information for quantitative analysis.
Second, risk analysis can be difficult to parameterize, analyze, and communicate effectively. The complexity of risk factors and their interdependencies make it challenging to assign precise numerical values to them.
Third, quantitative risk analysis is often limited by software and hardware requirements. The computational power and resources needed to perform complex quantitative analysis may not be readily available to everyone.
