You are designing a feature to allow users to customize their dashboard widgets. How would you approach prioritizing which widgets to include and how to allow users to rearrange them while ensuring usability and performance?

Use RICE scoring to rank widgets, then apply the CIRCLES framework to map user tasks and context. Prioritize based on impact, confidence, effort, and reach. Prototype a drag‑and‑drop UI, run A/B tests, and iterate based on usability metrics and performance benchmarks.

I would start by gathering data on current widget usage and user goals, then apply RICE scoring to quantify impact, reach, confidence, and effort for each widget idea. Next, I’d use the CIRCLES framework to map the context, user goals, and tasks, ensuring the design aligns with real workflows. With a prioritized list, I’d prototype a drag‑and‑drop interface, conduct usability tests with representative personas, and measure performance impact via load time and memory usage. Iterations would focus on reducing friction points, simplifying the UI, and ensuring accessibility. Finally, I’d launch the feature with A/B testing to validate improvements, tracking metrics such as task completion time, widget adoption rate, and Net Promoter Score.
