Consumer Product Efficiency Testing

I need a clear, repeatable way to quantify the efficiency of a consumer-grade product that is currently in late-stage development. The goal is to design and carry out a performance-measurement protocol, gather raw data under controlled conditions, analyse the results, and deliver a concise report that a non-technical stakeholder can understand at a glance. The scope centres on efficiency only—speed, durability and other metrics are not required at this stage—so every test, instrument choice and data point should directly support that single KPI. You are free to propose the most suitable tools (e.g., high-precision power meters, data loggers, statistical software such as R, Python/pandas) provided they produce reproducible results. Deliverables • A brief test plan outlining methodology, instrumentation and acceptance limits • The complete, unaltered data set in CSV or XLSX format • A summary report highlighting efficiency findings, key observations and any actionable insights Acceptance criteria • Test plan approved before execution • Measurements repeatable within ±2 % across three trials • Report written in clear, jargon-free English, no more than ten pages Once we agree on the protocol, I will ship the product and make any additional technical details available. Let me know if you foresee compliance or calibration requirements so we can address them early.
