Build a metric tree for Vision Pro after a major redesign

Problem Statement Description

Product context: Apple is a consumer hardware, software, and services company; its products include iPhone, iPad, Mac, Apple Watch, AirPods, iOS, App Store, iCloud, Apple Music, and Apple TV+.

Apple has recently shipped a major redesign of Vision Pro, with a particular focus on improving the experience for creators who use spatial computing for design, video, 3D workflows, collaboration, and content review. The redesign may affect onboarding, comfort, content creation flows, app usage, ecosystem integration, and long-term retention, so leadership needs a clear way to understand whether the redesign is working.

Your task is to build a metric tree that connects the redesigned Vision Pro experience to business and user outcomes. The metric tree should help Apple evaluate creator value, product engagement, hardware-software experience quality, and downstream ecosystem impact without relying on a single vanity metric.

Be explicit about how you would define each metric, who is included in the denominator, what events or signals need to be instrumented, and how the tree would be used to diagnose success or failure after launch. Assume this is for a premium Apple product where privacy, accessibility, device quality, and ecosystem trust matter.

The experience should consider:

- The primary user segment: creators using Vision Pro for productive or creative workflows

- A clear top-level success metric and how it breaks down into input, output, and guardrail metrics

- Metric definitions, denominators, time windows, and relevant cohorts such as new users, existing users, power users, and app-specific creator segments

- Instrumentation needed across device setup, app usage, session quality, creation workflows, sharing/exporting, and cross-device continuity

- Guardrails around comfort, safety, accessibility, privacy, hardware performance, battery, app crashes, and user frustration

- How to distinguish redesign impact from seasonality, marketing, app ecosystem changes, or hardware availability

- How the metric tree would support decisions such as iterating the redesign, investing in creator tools, or addressing workflow drop-offs

The goal is to demonstrate that you can translate a major Vision Pro redesign into a structured measurement framework that is actionable, privacy-conscious, and useful for both product and executive decision-making.
