Define success metrics for Android OS.

Introduction

Defining success metrics for Android OS requires a comprehensive approach that considers the complex ecosystem of users, developers, device manufacturers, and Google's strategic objectives. To tackle this product success metrics challenge effectively, I'll follow a structured framework covering core metrics, supporting indicators, and risk factors while considering all key stakeholders.

Step 1

Product Context

Android OS is an open-source mobile operating system developed by Google. It powers a vast array of smartphones, tablets, and other connected devices worldwide. Key stakeholders include:

1. End users: Seeking a seamless, feature-rich mobile experience
2. Device manufacturers: Looking to differentiate their products
3. App developers: Aiming to reach a large user base
4. Google: Driving adoption of its services and ecosystem

User flow typically involves device setup, app installation, daily usage of core features (calls, messaging, web browsing), and periodic system updates. Android competes primarily with Apple's iOS, differentiating itself through customization options and a more open ecosystem.

In terms of product lifecycle, Android OS is in the maturity stage, with a dominant market share but facing challenges in emerging markets and new device categories.

Software-specific context:

• Platform: Linux kernel with custom modifications
• Integration points: Hardware abstraction layer, OEM customizations
• Deployment model: OTA updates, factory images for new devices
