Prepare the data
Use consented account histories with time-bounded features and exclude post-departure information.
01 / THE IDEA
Customer Churn Prediction in practice.
Churn prediction requires a precise observation window and a later departure outcome. A score identifies association; it does not prove that a retention intervention will help.
Real-world use case · Proposed extension
A possible application for subscription support teams: Help subscription support teams investigate recurring service issues and offer useful assistance. This extension is not delivered by the supplied starter.
02 / THE BUILD
How to build a customer churn prediction project
step by step.
Build the experiment
Train a calibrated binary baseline and compare it with a simple recency rule.
Evaluate the result
Evaluate precision-recall and calibration on later accounts, checking important customer groups.
Define a reviewable output
Create a staff-reviewed support queue with reasons, opt-outs and no automated penalties.
03 / SOURCE SNAPSHOT
What the customer churn prediction starter actually does.
The supplied starter creates 800 synthetic binary-classification rows with ten numeric features. It makes a stratified train/test split, fits a scaled RandomForestClassifier pipeline and prints a classification report.
SOURCE EXCERPTPython
model = Pipeline(
steps=[
("scale", StandardScaler()),
("classifier", RandomForestClassifier(
n_estimators=250, random_state=RANDOM_STATE)),
]
)
model.fit(X_train, y_train)
predictions = model.predict(X_test)
print(classification_report(y_test, predictions))Important limitation
The source has synthetic labels rather than customer histories or churn outcomes. Synthetic binary classification does not establish performance on the proposed application. The source report uses one split; it supplies no deployment or real-world validation.
04 / BEYOND THE CLASSROOM
Where a customer churn prediction project could go next.
PROPOSED BUSINESS CONCEPT
Customer Churn Prediction: a pilot concept
Proposed extension: Help subscription support teams investigate recurring service issues and offer useful assistance.
WHO IT COULD SERVESubscription support teams
FIRST MVPCreate a staff-reviewed support queue with reasons, opt-outs and no automated penalties.
KEY RISKPrivacy and manipulative targeting
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
05 / WHAT YOU TAKE AWAY
What a customer churn prediction project puts on your resume.
- Train a calibrated binary baseline and compare it with a simple recency rule.
- Evaluate precision-recall and calibration on later accounts, checking important customer groups.
- Create a staff-reviewed support queue with reasons, opt-outs and no automated penalties.
- Explain this limitation: The source has synthetic labels rather than customer histories or churn outcomes.

06 / QUESTIONS STUDENTS ASK
Customer Churn Prediction project FAQs.
- Is this suitable as a final year project?
- Yes — it’s a solid intermediate ML practice for final year students, emphasising problem framing, feature engineering and evaluation rather than production deployment.
- What skills and tools do I need to complete it?
- You should know Python, pandas, scikit-learn, basic statistics and model evaluation metrics; familiarity with time windows and business context for churn helps.
- How should I evaluate progress and expected effort?
- Benchmark models using accuracy, ROC-AUC, precision/recall and calibration; expect several weeks to refine features, validate time-based splits, and test intervention assumptions. Note the starter provides synthetic labels rather than real customer histories.
