I went with on-time delivery rate as my North Star and then had to defend why that beats cost-per-package or utilization.
Start by clarifying the COO's goals and the company's strategic priorities, then propose a North Star metric that balances customer experience and operational efficiency. Justify your choice by linking it to business outcomes and discuss how it would be supported by secondary metrics.
Pro tip: Choose a metric that is actionable and aligns with the company's strategy, and be prepared to explain how it would be instrumented and used in decision-making. Avoid generic metrics like 'on-time delivery' without context; instead, frame it as a composite or ratio that captures trade-offs.
Ask questions to understand the company's strategic focus, such as cost leadership vs. service differentiation, and the COO's key responsibilities.
Brainstorm potential North Star metrics that reflect operational health, such as on-time delivery rate, cost per package, or customer satisfaction.
Assess each candidate against criteria like alignment with strategy, actionability, and ability to drive trade-off decisions. Choose one that best captures the COO's impact.
Specify how the metric is calculated, its components, and how it would be tracked. For example, 'Perfect Order Rate' = % of orders delivered on time, in full, without damage, and with accurate documentation.
Explain how the North Star metric would be supported by a dashboard of secondary metrics to diagnose issues and avoid unintended consequences.
