Yuvraj’s approach

Metric: Booking confirmation error rate Where: Globally When: Over the last month target metric= failed confirmations/total booking attempts)

Scope: across all platforms- web, ios and android? Also is this 5% global aggregate or region wise?

Segmentation: platform: web, android, ios region: Europe, USA, Asia Payment method: Credit/debit card, Wallet Booking type: Instant, Scheduled to book User segment: new vs repeated user

Possible clauses: Technical issues: API failure/downtime, payment gateway failure, server issues Product updates: new version has checkout flow bugs Regulatory issues, data issues User behaviour: spike in fraud accounts, attempts or invalid payment details

Most likely cause: Recent product release Payment gateway issues

Validation: Compare error rates by platform, region, payment method Check if error rates increased after new release Check error logs for failed API calls or payment issues Rollback to most recent version to verify if error rate drops

Fixes: Rollback to stable release Improve error message at UI level for users Strict QA for new releases More payment provider options in checkout
