Executive summary
A pipeline that continuously ingests customer feedback from every channel — reviews, tickets, surveys, and social — classifies sentiment and topics, and surfaces emerging themes before they become churn. It quantifies what customers actually feel, alerts on negative spikes, and hands leaders a clear, trended picture with representative quotes.
Business problem
Customer feedback is scattered across platforms and mostly unread at scale. Negative trends are noticed only after they have done damage — canceled accounts, one-star reviews, or a viral complaint. Teams lack an objective, ongoing read on sentiment and its drivers.
Architecture

Data flow
- 1
Feedback from reviews, tickets, surveys, and social lands in an S3 data lake.
- 2
Comprehend scores sentiment and extracts entities; Bedrock clusters items into themes and likely root causes.
- 3
Scored records and trend aggregates are stored in DynamoDB.
- 4
Negative spikes trigger SNS alerts to the responsible team in near real time.
- 5
QuickSight dashboards show sentiment over time, top themes, and representative quotes for leadership.
Security considerations
- Customer feedback and any PII encrypted at rest and in transit.
- PII detection and optional redaction before analysis.
- Least-privilege IAM; source credentials in Secrets Manager.
- Aggregated reporting avoids exposing individual records unnecessarily.
Cost considerations
- Comprehend (per unit of text) and Bedrock (per theme run) are the main variable costs.
- Event-driven processing means you pay only for new feedback.
- S3 and DynamoDB are inexpensive with lifecycle tiering.
Scalability
- Serverless throughout; scales with feedback volume across channels.
- New sources attach as adapters into the same lake.
- Theme taxonomies and alert thresholds are configurable per business.
Deployment roadmap
Phase 1 — Sources & taxonomy
Week 1- — Connect feedback channels and define themes
- — Provision AWS foundation and data lake
Phase 2 — Build & visualize
Weeks 2–4- — Build classification and theme extraction
- — Stand up dashboards and spike alerts
Phase 3 — Validate & tune
Week 5- — Validate sentiment accuracy on your data
- — Tune thresholds and theme clustering
Future enhancements
- Churn-risk scoring linked to individual accounts.
- Competitor sentiment benchmarking.
- Closed-loop follow-up workflows for detractors.
- Product and CX prioritization tied to theme volume.
