Product Management Root Cause Analysis Question: Investigating battery charging speed decrease for StoreDot's EV technology

Introduction

StoreDot's extreme fast charging battery technology has experienced a 15% decrease in charging speed over the past quarter, raising concerns about the product's performance and market positioning. This analysis will systematically investigate the root cause of this issue, considering technical, user behavior, and external factors that may have contributed to the slowdown.

Framework overview

This analysis follows a structured approach covering issue identification, hypothesis generation, validation, and solution development.

Step 1

Clarifying Questions (3 minutes)

  • Looking at the timing, I'm thinking there might be a seasonal component. Has this decrease been observed in previous quarters or is it unique to this one?

Why it matters: Helps distinguish between cyclical patterns and new issues. Expected answer: No previous seasonal patterns observed. Impact on approach: If seasonal, we'd focus on adapting to cyclical demand; if new, we'd investigate recent changes.

  • Considering the specificity of the 15% decrease, I'm curious about our measurement precision. Has there been any change in how we measure or define charging speed recently?

Why it matters: Ensures we're addressing a real issue, not a measurement artifact. Expected answer: No changes in measurement methodology. Impact on approach: If measurement changed, we'd recalibrate our analysis; if not, we'd focus on actual performance factors.

  • Given the nature of battery technology, I'm wondering about the test environment. Have there been any changes in the testing conditions or battery samples used?

Why it matters: Isolates whether the issue is with the technology itself or testing variables. Expected answer: Testing conditions have remained consistent. Impact on approach: If conditions changed, we'd standardize testing; if not, we'd investigate the technology itself.

  • Thinking about product lifecycle, I'm curious about the age of the batteries being tested. Are we seeing this decrease across all production batches or just newer/older ones?

Why it matters: Helps identify if it's a production issue or a degradation problem. Expected answer: The decrease is observed across all batches. Impact on approach: If batch-specific, we'd focus on production; if universal, we'd investigate the technology more broadly.
