What this question tests

Metrics design for a hardware product, checking you connect sales figures to genuine usage and satisfaction indicators.

Clarify what success means here, likely a mix of commercial performance and actual usage, since hardware success on units sold alone can mask poor engagement.
Propose commercial metrics: unit sales, revenue, and attach rate for accessories like the Pencil or keyboard.
Propose usage metrics: daily or weekly active use, app category usage split between consumption and productivity, and how that compares to the standard iPad.
Propose satisfaction metrics: return rate, and app store or support ticket sentiment around Pro-specific features like the higher-end display or performance.
Add a segment-specific metric: adoption among professional use cases, like design or video editing, since that is the Pro's differentiated audience versus the base iPad.
Combine into a short scorecard, explicitly flagging that units sold alone is an insufficient success measure without usage and retention data.

Explicitly distinguishes commercial success from genuine usage success, noting units sold can be high while usage still disappoints if buyers don't adopt Pro-specific workflows.
Proposes a segment-specific metric, professional or creative use case adoption, since that is what differentiates the Pro from the standard iPad.
Names accessory attach rate as a meaningful proxy for whether buyers are using Pro-specific capabilities, not just buying it as a bigger iPad.
Flags return rate and support sentiment as a guardrail against a product that sells well but disappoints on delivered value.

Measuring success purely by units sold or revenue, ignoring usage or satisfaction.
Not distinguishing Pro-specific success metrics from generic iPad metrics.
Ignoring accessory attach rate, which is a strong signal of intended-use adoption for a device like this.

How would you measure whether professionals specifically are getting value from the Pro versus casual buyers?
What would a high return rate tell you that unit sales alone wouldn't?
