How would you define the success of BT Group's Digital Voice landline replacement service?

Introduction

Defining the success of BT Group's Digital Voice landline replacement service requires a comprehensive approach that considers multiple stakeholders and metrics. To effectively address this product success metrics challenge, I'll follow a structured framework covering core metrics, supporting indicators, and risk factors while considering all key stakeholders.

Step 1

Product Context

BT Group's Digital Voice is a next-generation landline service that replaces traditional copper-wire phone lines with internet-based technology. This transition is part of BT's broader strategy to modernize its infrastructure and prepare for the eventual phaseout of the Public Switched Telephone Network (PSTN).

Key stakeholders include:

• Residential customers: Seeking reliable, high-quality voice communication
• Business customers: Requiring dependable communication for operations
• BT Group: Aiming to reduce maintenance costs and improve service quality
• Regulatory bodies: Ensuring universal service obligations are met

User flow:

1. Customers receive information about the Digital Voice transition
2. They schedule an installation appointment
3. A technician installs the necessary equipment
4. Customers begin using the new service, potentially with a learning curve for new features

Compared to competitors like Virgin Media, BT's Digital Voice aims to leverage its extensive existing customer base and infrastructure. The service is currently in the growth stage of its lifecycle, with increasing adoption rates but still facing some challenges in rural areas.

Software considerations:

• Platform: Relies on Voice over Internet Protocol (VoIP) technology
• Integration points: Must work seamlessly with existing home internet setups
• Deployment model: Gradual rollout, region by region
