Drivetrain Method

  1. Define a business problem (models should be made to address a problem, problems should not be made to fit a model).
  2. Identify the inputs (levers) that affect this problem. How can the company change its inputs? Should they produce more of x or y? Or should they focus on providing for their current customer base or expand? These are examples of inputs that can be changed based on the predictions made by a model and it’s important to know what the possibilities of your model are.
  3. The third step is to find data or develop methods to collect data for this problem and construct your model (kind of crazy that what I used to think of as my whole job is all collated into one step.
  4. Optimize based on the predictions of the model and change the inputs.
