What is the primary purpose of prototyping and modeling in SAFe decisions?

• A. To document marketing strategy
• B. To replace all software development
• C. To finalize user interface design
• D. To support architectural decisions

Answer: (D)

Prototyping and modeling in SAFe are used to create tangible representations of system options so architectural direction can be validated before large-scale work starts. By building lightweight prototypes and modeling how components will interact, teams uncover risks, test performance and scalability assumptions, and compare different design trade-offs. This evidence-based exploration helps stakeholders converge on an approach that best supports business goals while respecting constraints, guiding the architectural runway with real insight. They aren’t about marketing plans, replacing development, or finalizing UI on their own; those areas may be informed by prototypes, but the primary aim here is to inform and de-risk architectural decisions.
