What action should be taken if a decline in product usage is observed?

When observing a decline in product usage, it is crucial to utilize the Customer Success Playbook (CSP) and refer back to it for an internal review. The CSP provides structured methodologies and strategies that can help identify the underlying causes of decreased usage. This process involves analyzing customer health scores, understanding engagement levels, and identifying any potential obstacles customers may be facing while using the product. By revisiting these internal resources, customer success professionals can gather insights that lead to targeted actions tailored to the customer's unique situation, ultimately facilitating a more focused response to improve the user's experience.

The other options, while they may provide some value, do not directly address the immediate need to understand and resolve the drop in usage as effectively as reviewing the CSP. Engaging with customer feedback is beneficial for understanding sentiment but may not lead to actionable insights without further analysis. Increasing marketing outreach might attract new users but won't necessarily retain current users facing issues. Setting up a technical review session could help address specific product-related problems but might not be as comprehensive without the insight derived from the internal review process outlined in the CSP.
