Why has the average time to complete a transaction on Netcompany's e-commerce platform increased by 45 seconds over the past month?

Introduction

The recent 45-second increase in average transaction completion time on Netcompany's e-commerce platform is a critical issue that demands immediate attention. This significant slowdown could lead to user frustration, abandoned carts, and ultimately, lost revenue. In this analysis, I'll systematically investigate the root cause, generate data-driven hypotheses, and propose actionable solutions to address this performance degradation.

Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in the system. Has there been any significant update or deployment to the e-commerce platform in the past month?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, there was a major update. Impact on approach: If yes, we'd focus on the changes made; if no, we'd look at gradual degradation factors.

• Considering user segments, I'm wondering if this slowdown affects all users equally. Are we seeing this 45-second increase across all user types and geographies?

Why it matters: Helps identify if it's a global issue or specific to certain user groups. Expected answer: The slowdown is more pronounced in certain regions. Impact on approach: If localized, we'd investigate regional factors; if global, we'd look at core system issues.

• Thinking about the transaction funnel, I'm curious about where exactly the delay is occurring. At which step in the transaction process is the most significant slowdown happening?

Why it matters: Pinpoints the specific area of the system to focus on. Expected answer: The delay is primarily in the payment processing step. Impact on approach: We'd concentrate our investigation on the identified step and its associated systems.

• Considering potential data anomalies, I'm wondering about our measurement accuracy. Has there been any change in how we measure or define "time to complete a transaction" in the past month?

Why it matters: Ensures we're not chasing a non-existent problem due to measurement errors. Expected answer: No changes in measurement methodology. Impact on approach: If changed, we'd need to reassess the validity of the reported increase; if not, we can proceed with our analysis.
