Real-World Example: Customer Churn Prediction Project

Project Profile

Organization: TelecomPro (telecommunications provider)
Challenge: 18% annual customer churn rate resulting in $24M revenue loss
Objective: Reduce churn by 25% through predictive analytics and targeted interventions
Team Size: 8 specialists across data and business roles
Timeline: 3-month development, followed by iterative improvements

Sprint 1-2: Discovery & Data Assessment

Day 1: Project Kickoff Meeting

Product Owner

We're facing an 18% annual churn rate, costing us $24M. Our goal is to build a predictive model that helps us identify at-risk customers before they leave. Key success metric is a 25% reduction in churn within 6 months of implementation.

10:05 AM

Business Owner (Customer Service Director)

From our initial analysis, we believe service interruptions, billing issues, and competitive offers are key drivers. We have data from our CRM, billing system, and network monitoring that should be relevant.

10:12 AM

Data Steward

For CRM data access, we'll need to ensure GDPR compliance. Some customer data is restricted. I'll document what fields are available and any anonymization requirements. Also, the data quality in the billing system has been problematic - about 15% of records have inconsistencies we'll need to address.

10:18 AM

Data Engineer

I'll start setting up the data pipeline to extract and merge data from these systems. The network monitoring data is in a different format and refreshes hourly - we'll need to decide on the integration approach. Can we schedule a data architecture session tomorrow?

10:25 AM

Data Scientist

Based on similar projects, we should aim for a model that gives us 80%+ recall on high-risk customers. I'll need historical data going back at least 12 months with churn outcomes labeled. Let's also identify what intervention data we have to measure past retention efforts' effectiveness.

10:32 AM

Project Manager

Great input everyone. Let's organize our first two sprints: Sprint 1 focused on data access, quality assessment, and exploratory analysis; Sprint 2 on feature engineering and initial modeling. I'll create the backlog items and we'll prioritize them in our planning session tomorrow.

10:40 AM

Sprint 1-2 Key Outcomes:

- Data sources identified: CRM, billing, network, customer support, product usage
- Data quality assessment: 15% of billing records incomplete, requiring cleansing
- Privacy compliance plan documented with Data Steward approval 
- Initial data pipeline implemented connecting 3 primary systems
- Exploratory analysis revealed 5 potential churn indicators
- Initial feature set of 27 variables documented
- Decision to use 18 months of historical data with 3-month lead time

Sprint 3-4: Model Development

Day 15: Model Approach Workshop

Data Scientist

Based on our exploratory analysis, I propose we try three modeling approaches: logistic regression as a baseline, gradient boosting for better performance, and a deep learning approach to capture complex patterns. Our dataset has 120,000 customers with 18 months of history and 21,600 churn events.

2:05 PM

Product Owner

For business adoption, we need model explainability. Our retention team needs to understand why customers are flagged as high-risk to devise appropriate interventions. How does each approach handle this?

2:12 PM

Data Scientist

Good point. Logistic regression is most interpretable but may miss complex patterns. For gradient boosting, we can use SHAP values to explain predictions. The deep learning approach would be the least explainable but potentially most accurate. Given your requirement, I suggest we prioritize the gradient boosting approach with SHAP for our initial implementation.

2:18 PM

Data Engineer

For implementation, we'll need to ensure the feature pipeline can run daily. Some metrics like "days since last customer service call" need to be calculated dynamically. I'll update our pipeline to handle this and create a feature store for consistent access.

2:25 PM

MLOps Engineer

Let's discuss deployment requirements early. Will this be batch scoring or real-time? For customer service integration, we'll need API endpoints with sub-second response times. Also, how often will the model need retraining?

2:30 PM

Business Owner

Daily batch scoring should be sufficient for our retention campaigns, but we also need real-time access when customers call in. Retraining quarterly makes sense since promotions and pricing change on that cycle, which affects churn patterns.

2:35 PM

Project Manager

Let's plan the next two sprints accordingly: Sprint 3 for model development and evaluation with the gradient boosting approach, focusing on explainability; Sprint 4 for refinement and preparation for deployment with both batch and API endpoints. I'll update our roadmap and sprint backlog.

2:42 PM

Sprint 3-4 Key Outcomes:

- Gradient boosting model developed with 83% recall on high-risk customers
- SHAP implementation providing feature importance for each prediction
- Customer risk segments defined: High (>70% risk), Medium (30-70%), Low (<30%)
- Feature store implemented with daily refresh cycle
- Initial API developed for real-time scoring with 120ms average response time
- A/B testing framework designed for intervention effectiveness measurement
- Model validation completed with holdout data showing consistent performance

Sprint 5-6: Deployment & Initial Results

Day 32: Pre-Deployment Review

MLOps Engineer

The deployment infrastructure is ready. We've implemented daily batch scoring that creates a ranked churn risk file for the retention team, and a real-time API for the call center application. Monitoring includes data drift detection, performance metrics, and system health. All documented in the runbook.

11:05 AM

Data Steward

I've reviewed the deployment plan. All PII is properly handled, and we're only exposing necessary fields to each user group. We've documented the data flows and retention policies in our governance platform. One concern: we need audit logging for who accesses customer risk scores.

11:12 AM

MLOps Engineer

Good catch. I'll add comprehensive audit logging before deployment. Should be ready by tomorrow.

11:15 AM

Product Owner

The retention team is ready to start using the model outputs. We've developed tailored intervention strategies for different risk segments and causes. Our dashboard to track intervention effectiveness is also ready. Any concerns before we go live next Monday?

11:20 AM

Data Scientist

Let's make sure we have a clear process for feedback collection. When retention specialists interact with flagged customers, we need to capture the outcome to improve future predictions. Also, we should implement a progressive rollout - maybe 25% of high-risk customers in week 1, then scale up based on results.

11:28 AM

Business Owner

Agreed on progressive rollout. My team has prepared a feedback form in the CRM system to capture intervention outcomes. We've also scheduled weekly review sessions to discuss the model's effectiveness and any adjustments needed to our retention approaches.

11:35 AM

Project Manager

This sounds good for deployment. Let's finalize Sprint 5 with the deployment and initial rollout, then use Sprint 6 for monitoring, feedback collection, and initial refinements. I've scheduled a go/no-go meeting for Friday with all stakeholders. The executive dashboard for churn reduction tracking will also be ready by Monday.

11:42 AM

Sprint 5-6 Key Outcomes:

- Production deployment completed successfully
- Progressive rollout: 25% week 1, 50% week 2, 100% week 3
- Data pipeline stability at 99.8% with automated recovery
- Real-time API integrated with call center application

Common Challenges in Data & Analytics Teams

Role Boundary Confusion

Symptom: Overlapping responsibilities between Data Scientists and Data Analysts
Impact: Duplicated efforts, inconsistent approaches to similar problems
Solution: Clear RACI matrices for each project phase, documented capability models
Example: "At FinTech Inc., both analysts and scientists were building predictive models, leading to inconsistent results. Creating distinct swim lanes based on model complexity resolved the issue."

Technical-Business Translation Gap

Symptom: Data teams building technically impressive solutions that don't solve business problems
Impact: Low adoption, perception that data initiatives don't deliver value
Solution: Stronger Product Owner role with data literacy, regular business validation
Example: "ManuCorp's predictive maintenance model achieved 92% accuracy but wasn't used because it didn't integrate with technicians' workflows. Adding a UX designer and workflow specialist to the team solved this."

Data Governance Neglect

Symptom: Data quality issues discovered late in projects, compliance gaps
Impact: Project delays, reduced model performance, regulatory risks
Solution: Involve Data Stewards from project inception, include data quality in Definition of Ready
Example: "HealthCare Plus had to delay their patient risk model by 3 months after discovering PII handling issues late in development. Now Data Stewards sign off on all project charters."

Model Deployment Gap

Symptom: Models work in development but fail or degrade in production
Impact: Reduced business value, lost confidence in data science
Solution: Dedicated MLOps Engineers, production-like development environments
Example: "RetailCo's recommendation engine performed 40% worse in production than in testing due to data latency issues. Adding MLOps specialists improved deployment success from 60% to 95%."

Sprint Misalignment for Data Work

Symptom: Data preparation and model training don't fit standard sprint timeboxes
Impact: Incomplete sprint deliverables, pressure to cut corners on quality
Solution: Adapted sprint cadences, spike sessions for exploration, progressive elaboration
Example: "BankCorp moved from 2-week to 3-week sprints for their ML teams, with model training running asynchronously to avoid blocking other work."

Best Practices for Data & Analytics Teams

Team Structure & Collaboration

Establish clear role definitions but embrace T-shaped skills development
Create cross-functional pods with business and technical representation
Include Data Stewards in sprint planning and reviews
