Why has Talkdesk's Interactive Voice Response (IVR) system seen a 15% drop in successful call routing over the past month?

Introduction

Talkdesk's Interactive Voice Response (IVR) system has experienced a 15% drop in successful call routing over the past month, indicating a significant issue that requires immediate attention. This analysis will systematically identify, validate, and address the root cause while considering both short-term fixes and long-term strategic implications.

I'll approach this problem by first clarifying the context, then ruling out external factors before diving deep into the product's user journey, metric breakdown, and data analysis. From there, I'll form hypotheses, conduct root cause analysis, and propose validation methods and solutions.

Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might have been a recent system update. Has there been any significant changes to the IVR system in the past 1-2 months?

Why it matters: System changes often correlate with performance shifts. Expected answer: Yes, there was a minor update. Impact on approach: If yes, I'd focus on change management and regression testing processes.

• Considering user segments, I'm curious about the distribution of the issue. Is the 15% drop consistent across all customer types or more pronounced in specific segments?

Why it matters: Helps identify if the problem is systemic or segment-specific. Expected answer: The drop is more significant in enterprise customers. Impact on approach: If segmented, I'd investigate unique characteristics of affected segments.

• Regarding performance metrics, has there been any change in how "successful call routing" is defined or measured in the past month?

Why it matters: Ensures we're comparing apples to apples in our analysis. Expected answer: No changes in definition or measurement. Impact on approach: If changed, I'd focus on metric consistency and data integrity.

• Thinking about user behavior, have you noticed any changes in call patterns or volume that might explain the routing issues?

Why it matters: User behavior shifts can impact system performance. Expected answer: Call volumes have remained stable. Impact on approach: If volumes changed, I'd investigate capacity and load balancing.
