Define Key Performance Indicators (KPIs) for a Product Manager Role

As a Project Management Office (PMO) Lead, you need to establish clear performance metrics for a 'Product Manager' role overseeing a B2B SaaS product. These KPIs should drive accountability and measure success.

**Role**: PMO Lead / Project Manager
**Context**: Setting clear expectations and measurable goals for a crucial product-focused role.
**Specifics**: Identify at least 5-7 measurable KPIs that directly relate to the Product Manager's responsibilities and contribute to overall product and business success (e.g., product adoption, customer satisfaction, revenue growth, feature usage). For each KPI, explain why it's important and how it would be measured.
**Output**: A list of KPIs with explanations of their importance and proposed measurement methods.
