Customer Health Metrics and Scoring Questions

Designing, implementing, and operating customer health measurement systems that combine multiple signals into scores or segments to predict outcomes such as churn, retention, and expansion. Includes selecting and justifying leading indicators versus lagging indicators and choosing relevant data inputs such as product usage patterns, engagement frequency, feature adoption, support ticket volume, payment and billing signals, account changes, and customer sentiment including net promoter score. Covers approaches to constructing scores using rule based logic, weighted indices, statistical models, and machine learning models, as well as feature engineering, handling missing data, and robustness checks. Describes calibration of score ranges and thresholds into actionable risk or opportunity categories, validation techniques including backtesting and cohort analysis, evaluation metrics and performance monitoring, and methods for measuring business impact through lift analysis and controlled experiments. Also addresses operationalization and production considerations such as batch versus real time scoring, event driven pipelines, integration with customer relationship management systems and workflow automation, dashboards and alerts for operational teams, prioritization and playbook design for interventions, monitoring for data drift and model staleness, feedback loops for retraining and improvement, explainability for stakeholder trust, and governance for privacy and data compliance.

Implement in Python a function that takes a DataFrame of normalized signals (each column 0-1) and a dictionary of weights, then computes a weighted customer health score in range 0-100. Ensure your function supports missing signals by re-normalizing weights for available features and allows an optional monotonic transform (e.g., logit). Write concise, production-ready code.

Design an operational dashboard for Customer Success leadership to monitor customer health across product, support, and finance signals. List key charts (with axes), alert rules, drill-down flows for CSMs, and how you would measure whether dashboards lead to better outcomes.

CSMs have limited daily capacity. Design a prioritization heuristic that ranks accounts for proactive outreach using inputs: health_score (0-100), ARR, time_since_last_contact (days), and predicted expansion probability. Describe the formula, how you would tune it, and a simple simulation to evaluate its effectiveness.

Design a backtesting and cohort analysis plan to validate a new customer health score. Specify data splitting (time windows), cohort definitions, key metrics to compute (e.g., churn-rate-by-score-decile over 90 days), and how you would check for data leakage and confounding variables.
MediumTechnical

Using scikit-learn in Python, outline and implement a training pipeline for a churn classifier using logistic regression. Pipeline should include imputation for numeric features, one-hot encoding for categoricals, standard scaling, cross-validation (time-aware if data is time-ordered), and output AUC and precision@10% (top decile) on validation. Describe key choices in code comments.
