Which design approach helps with design flexibility to support changing requirements?

The correct answer—set-based design—emphasizes flexibility in the design process by exploring multiple alternatives simultaneously rather than committing to a single solution early on. This approach allows teams to gather information, assess various design options, and make informed decisions based on their changing needs and any evolving requirements. As requirements often change during the development process, set-based design enables teams to adapt and pivot as necessary, resulting in solutions that are more aligned with current project goals and stakeholder expectations.

Set-based design fosters collaboration and innovation, allowing for different ideas to coexist and evolve, which helps mitigate the risks associated with premature decisions. This adaptability is crucial in environments like Agile or SAFe, where iterative feedback and adaptive planning are key principles.

In contrast, the other design approaches do not inherently emphasize flexibility in response to changing requirements. Point-based design focuses on specific solutions without considering multiple options. Emergent architecture evolves over time but may not adequately address requirements until they are fully understood. Intentional design strives for explicit alignment with goals but can lead to rigid structures if changes are needed. Therefore, set-based design is the most effective in accommodating variability in requirements while still maintaining design integrity.
