Our Approach
A focused, strategic approach accelerates data value. We help you translate business priorities into analytics initiatives and build a strategic roadmap for growth. This ensures that your first use cases deliver results to strengthen buy-in and investment going forward. Our typical approach has five key elements.
Business translation
In this phase, we work with your domain experts to define the objective of the project, key performance indicators, boundary conditions and the approach we will take to solve the business case.
Data analysis
We collect, clean, structure, and analyze internal and external data to identify relevant patterns.
Modelling
Machine learning models are trained, selected, and optimized based on qualitative and quantitative factors.
Evaluation
Evaluation of model results in collaboration with your team enables us to further refine the algorithms.
Implementation
We help you implement the model in the production environment where it can begin delivering return on investment for your business.
The Milliman Data Science Team has experience in a variety of industries and use cases.
Predicting customer behavior
Churn modelling: Predict customers at risk of leaving
If your business relies on a subscription model, knowing which customers are likely to cancel can provide you with an important competitive advantage. It is a lot more expensive to acquire a new customer than to keep an existing one. Our predictive churn models deliver high accuracy across industries including energy, telecom, insurance, and fitness.
