Architectural runway is assisted by?

• A. Design spikes, emergent design, refactoring modeling, automated deployment
• B. Design spikes, emergent design, refactoring modeling, test automation
• C. Marketing research, customer interviews, branding
• D. Regulatory compliance documents, audits, licenses

Answer: (B)

Architectural runway is the evolving technical foundation that enables upcoming work, kept healthy through ongoing exploration, deliberate design evolution, and rapid feedback. Design spikes are time-boxed experiments to investigate uncertain technical options, helping you choose viable approaches without committing prematurely. Emergent design acknowledges that architecture will naturally evolve as learning occurs, so you enable and guide that evolution rather than attempting to lock in every detail upfront. Refactoring and modeling support a clean, scalable architecture: refactoring improves structure without changing behavior, while modeling clarifies decisions and guides future work. Test automation provides fast, continuous validation as the architecture and features grow, ensuring changes don’t break core technical integrity. Together, these activities sustain and extend the architectural runway. The other options focus on market research, branding, or regulatory aspects rather than maintaining the technical foundation.
