The best way to enable a risk-based decision when considering the use of an emerging technology for data processing is to perform a gap analysis. A gap analysis is a technique that compares the current state and the desired state of a process, system, or capability, and identifies the gaps or differences between them. A gap analysis can help to evaluate the benefits, costs, risks, and opportunities of using an emerging technology for data processing, and to determine the feasibility, suitability, and readiness of adopting the emerging technology. The other options are not as helpful as a gap analysis, as they are related to the specific aspects or components ofthe data processing, not the overall assessment and comparison of the current and desired state of the data processing. References = Risk and Information Systems Control Study Manual, Chapter 1: IT Risk Identification, Section 1.2: IT Risk Identification Methods, page 19.
