Research Plan: Validate User Needs and Benchmark Competitors' Adoption of Group Calling
You are designing a research plan for a consumer communications product considering a group calling (voice/video) feature. Produce:
Part A — Survey (User Needs Validation)
Draft 8–10 concrete survey items (exact question text + response scales) to uncover:
- Use cases
- Ideal group size
- Willingness to invite others
- Acceptable latency
- Blockers
Include at least two randomized vignettes (e.g., different UI/latency trade-offs). Also specify:
- Sampling frame and recruitment method
- How responses will be linked to behavioral telemetry while preserving privacy
Part B — Competitor Benchmarking (Adoption Estimation)
Without internal data, outline how to estimate a U.S. adoption rate for group calling within ±20% relative error. Provide:
- Specific external signals and how to collect them (e.g., search trends, app store review mining, third-party mobile panels, web telemetry, WebRTC STUN/TURN traffic proxies via ethical/consented providers, public earnings remarks)
- A triangulation and calibration model to translate signals into adoption estimates
- Assumptions, bias risks, and validation steps (e.g., back-testing on known launches)
