Product Management Root Cause Analysis Question: Investigating NTT Global IP Network customer satisfaction decline

Introduction

NTT's Global IP Network service has experienced a 15% drop in customer satisfaction scores over the past quarter, signaling a significant issue that requires immediate attention. To address this problem, I'll employ a systematic approach to identify, validate, and resolve the root cause while considering both short-term fixes and long-term strategic implications.

Framework overview

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

Step 1

Clarifying Questions (3 minutes)

  • Considering the timing, I'm wondering if there have been any recent changes to the network infrastructure. Have there been any major upgrades or maintenance activities in the past quarter?

Why it matters: Infrastructure changes could directly impact service quality and user experience. Expected answer: Yes, there was a significant upgrade to our core routers. Impact on approach: If confirmed, we'd focus on post-upgrade performance and potential rollback strategies.

  • Looking at the customer base, I'm curious about the distribution of the satisfaction drop. Is this decline uniform across all customer segments, or are certain groups more affected?

Why it matters: Identifying specific affected segments could point to targeted issues or changes. Expected answer: Enterprise customers seem more affected than small businesses. Impact on approach: We'd prioritize investigating enterprise-specific features or service levels.

  • Considering external factors, I'm thinking about potential changes in the competitive landscape. Have any major competitors launched new services or pricing models recently?

Why it matters: Competitive pressures could influence customer perception and satisfaction. Expected answer: A competitor introduced a new high-speed tier at a lower price point. Impact on approach: We'd need to assess our value proposition and potentially adjust our offering.

  • Reflecting on internal processes, I'm wondering about any changes in customer support or service delivery. Have there been any significant alterations to our support structure or SLAs?

Why it matters: Changes in support quality or responsiveness could directly impact satisfaction scores. Expected answer: We've recently outsourced part of our customer support team. Impact on approach: We'd focus on evaluating the new support structure and identifying any gaps in service quality.
