Original prompt

Create a process document tailored for product managers at OctoAcme. The document should provide clear, actionable guidelines on the product management process, including:

• Product vision and strategy alignment
• Requirements gathering and prioritization
• Cross-functional collaboration
• Roadmap planning and communication
• Success metrics and reporting
• Iteration and continuous improvement

The document should be easy to follow, formatted in Markdown, and placed in the repository at the root level as product-management-process.md. It should reflect best practices for modern product management and be customized to reference "OctoAcme" where appropriate.
