If you were PM for a workplace chat app, what metrics would you use to measure its success?

Focus on identifying both quantitative and qualitative metrics that reflect user engagement, retention, and overall satisfaction with the chat app. Consider metrics such as Daily Active Users (DAU), Monthly Active Users (MAU), message volume, and user retention rates. Additionally, think about user feedback mechanisms like Net Promoter Score (NPS) or Customer Satisfaction Score (CSAT) to gauge user sentiment. Be prepared to explain why each metric is important and how it ties back to the app's goals, such as improving communication efficiency or enhancing team collaboration.
