Context
You are a Data Analyst at a digital payment app. Over the past month, the payment failure rate surged from an average of 2.1% to 6.8%, resulting in customer complaints and lost merchant transaction volume. The Head of Product wants your findings and a remediation strategy before the end of the workday.
Your Task
Present your findings to the Product Team in three parts:
- Recommendation — one concrete decision to address the payment failure spike.
- Impact — estimated changes in failure rate, transaction volume, and recovered revenue.
- Implementation Plan — execution stages including owner, sequence, and timeline.
