  1. Foundations: Customer Data & Analytics

    4 weeks
    Goals
    • Understand customer lifecycle stages, touchpoints, and journey mapping

    Resources
    • Khan Academy - Statistics and Probability
    • Mode Analytics SQL Tutorial
    • Coursera: Customer Analytics by Wharton
    • Kaggle: E-Commerce Behavior Dataset
    Milestone

    You can query a customer event database, build a cohort retention chart, and articulate where in a customer journey a decision engine would add value.

  2. Machine Learning for Decision-Making

    6 weeks
    Goals
    • Master supervised learning fundamentals: classification, regression, feature engineering
    • Learn uplift modeling and causal inference basics (double ML, meta-learners)
    • Understand multi-armed bandits: epsilon-greedy, Thompson sampling, UCB
    Resources
    • fast.ai Practical Machine Learning course
    • Coursera: Machine Learning by Andrew Ng
    • Causal Inference for the Brave and True (free online textbook)
    • Vowpal Wabbit bandit tutorial
    • Papers: 'A Tutorial on Thompson Sampling' (Russo et al.)
    Milestone

    You can build a basic contextual bandit model, run an uplift analysis on historical campaign data, and explain the exploration-exploitation tradeoff to a business audience.

  3. Real-Time ML Pipelines & CDP Architecture

    5 weeks
    Goals
    • Learn event-driven architecture with Kafka and streaming feature engineering
    • Understand CDP data models and identity resolution
    • Deploy a real-time inference endpoint using SageMaker or Vertex AI
    • Implement experiment tracking with MLflow
    Resources
    • Confluent Kafka 101 free course
    • Segment CDP documentation and Academy
    • AWS SageMaker Getting Started tutorials
    • MLflow documentation and quickstart
    Milestone

    You can build an end-to-end pipeline that ingests streaming customer events, computes features in real time, scores a decision model, and logs predictions for monitoring.

  4. LLM-Augmented Next Best Action

    4 weeks
    Goals
    • Learn prompt engineering for generating personalized action variants
    • Use LangChain to chain LLM calls with retrieval-augmented context from customer profiles
    • Build a prototype NBA system that combines a bandit model with LLM-generated content
    Resources
    • OpenAI API documentation and cookbook
    • LangChain documentation and Tutorials section
    • HuggingFace course on NLP and Transformers
    • DeepLearning.AI short courses on LangChain and ChatGPT prompt engineering
    Milestone

    You can build a working prototype where an RL model selects the action type and an LLM generates the personalized execution (message copy, agent script, offer framing) in real time.

  5. Production, Ethics & Business Impact

    5 weeks
    Goals
    • Design ethical guardrails: frequency capping, sensitivity rules, demographic fairness audits
    • Build executive-ready dashboards connecting model metrics to business KPIs
    • Practice stakeholder storytelling: translate model performance into revenue impact narratives
    • Study real-world NBA case studies from banking, telecom, and e-commerce
    Resources
    • Google Responsible AI Practices guide
    • Tableau or Looker dashboard tutorials
    • Harvard Business Review articles on AI-driven personalization
    • Case studies: McKinsey Next Best Action reports
    • Fiddler AI fairness documentation
    Milestone

    You can present a complete NBA system to business leaders - from data pipeline to model logic to ethical guardrails to measured business uplift - and handle challenging questions with authority.

Practice Projects

Apply your skills with hands-on projects. Ordered by difficulty.

E-Commerce Next Best Action Recommender

Beginner

Build a basic multi-armed bandit system for an e-commerce dataset that recommends the best promotional action (discount, free shipping, bundle offer, or no action) for each customer based on their browsing and purchase history. Use the UCB or epsilon-greedy algorithm and evaluate with simulated reward feedback.

Multi-armed banditsCustomer segmentationPython data analysis

Uplift Modeling for Marketing Campaigns

Intermediate

Using a publicly available marketing campaign dataset, build an uplift model (using the CausalML or EconML library) that identifies customers who will respond positively only if targeted. Compare treatment vs. control group outcomes and demonstrate incremental lift over a naive propensity model.

Real-Time NBA Pipeline with Kafka and Feature Store

Intermediate

Design and implement a real-time event processing pipeline using Apache Kafka that ingests simulated customer events, computes features on the fly, and serves predictions from a trained model via a REST API. Include a simple online feature store backed by Redis.

~45h
Event streamingReal-time feature engineeringModel serving

LLM-Powered Personalized Message Generator

Intermediate

Build a LangChain pipeline that takes a customer profile (demographics, recent interactions, predicted propensity) as input and generates personalized email subject lines and body copy for the recommended action. Include output validation, tone control, and A/B comparison with rule-based templates.

End-to-End NBA System for Telecom Churn Prevention

Advanced

Build a complete NBA system for a telecom churn scenario: ingest streaming customer usage data, compute behavioral features, train a contextual bandit model that selects from retention actions (loyalty offer, plan upgrade, callback, survey, or no action), generate personalized messaging via an LLM, and deploy with monitoring dashboards. Include fairness analysis across customer segments and a holdback experiment to measure uplift.

NBA Model Explainability and Compliance Dashboard

Advanced

Build an interactive dashboard (using Streamlit or Dash) that allows a compliance officer to query any customer, see the model's recommended action, the top features that drove that recommendation (via SHAP), the alternative actions considered and their scores, and a full audit trail of past actions and outcomes for that customer.
