How should Abbott balance increasing the accuracy of its FreeStyle Libre continuous glucose monitoring system versus extending battery life?

Introduction

Balancing the accuracy of Abbott's FreeStyle Libre continuous glucose monitoring system against extending its battery life presents a critical product trade-off. This scenario involves weighing the importance of precise glucose measurements against the convenience of longer-lasting devices. I'll analyze this trade-off by examining user needs, technical constraints, and business implications to provide a strategic recommendation.

Clarifying Questions (3 minutes)

• Based on the competitive landscape, I'm thinking accuracy might be a key differentiator. Could you share how our accuracy compares to leading competitors?

Why it matters: Helps determine if accuracy improvement is necessary for market positioning. Expected answer: We're slightly behind in accuracy but lead in battery life. Impact on approach: Would prioritize accuracy improvements if we're significantly behind.

• Considering user segments, I'm assuming we serve both Type 1 and Type 2 diabetics. Can you confirm our primary user base and their specific needs?

Why it matters: Different user groups may prioritize accuracy vs. battery life differently. Expected answer: Primarily Type 1 diabetics who require more frequent monitoring. Impact on approach: Would lean towards accuracy for Type 1 users who need precise, frequent readings.

• Looking at our revenue model, I'm guessing the device is sold at a premium with recurring sensor sales. Is this correct, and how does it impact our strategy?

Why it matters: Helps understand if longer battery life could impact recurring revenue. Expected answer: Correct, sensors are the primary revenue driver. Impact on approach: Might favor accuracy to justify premium pricing and maintain sensor sales frequency.

• From a technical standpoint, I'm curious about the relationship between accuracy and power consumption. Is there a direct trade-off, or are there other factors at play?

Why it matters: Determines if we can optimize both simultaneously or if it's a zero-sum game. Expected answer: Increased sampling frequency for accuracy does impact battery life. Impact on approach: Would explore innovative solutions to improve efficiency if direct trade-off exists.

• Regarding our product roadmap, are there any upcoming features or integrations that might influence this decision?

Why it matters: Ensures alignment with broader product strategy and future plans. Expected answer: Planning integration with insulin pumps in the next 18 months. Impact on approach: Would consider accuracy more critical for successful integration with other medical devices.
