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

AWS services

Amazon S3

  • Sentiment scoring and entity/topic detection
  • Language detection

Amazon Bedrock

AI / ML
  • Cluster feedback into themes and root causes
  • Draft representative summaries

Amazon DynamoDB

Database
  • Scored and tagged feedback records
  • Trend aggregates

Amazon SNS

Messaging
  • Alert owners on negative sentiment spikes

Amazon QuickSight

Observability
  • Sentiment trend and theme dashboards

Amazon EventBridge

Messaging
  • Trigger analysis on new feedback

Amazon CloudWatch

Observability
  • Logs, metrics, and cost alarms

Data flow

  1. 1

    Feedback from reviews, tickets, surveys, and social lands in an S3 data lake.

  2. 2

    Comprehend scores sentiment and extracts entities; Bedrock clusters items into themes and likely root causes.

  3. 3

    Scored records and trend aggregates are stored in DynamoDB.

  4. 4

    Negative spikes trigger SNS alerts to the responsible team in near real time.

  5. 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.
