Brief

The Drivetrain Approach, promoted by Jeremy Howard and summarized in Salman's close read, prescribes: define the goal, consider levers, gather and assess data, then implement an assembly-line process. Salman stresses prioritizing actionable steps that achieve objectives and treating model predictions as supplementary data, not as the actions themselves.

Why it matters

Jeremy Howard's 'Drivetrain Approach' (highlighted by Salman/@ForBo7_) outlines four steps: Define goal → Consider levers → Consider data → Implement assembly line.

Key details

  • Salman emphasizes that the most important element is having actions that directly fulfill the objective, and that model predictions should be treated as additional data rather than as actions.
  • Public mention occurred on 2026-06-23 when Jeremy Howard noted renewed interest in the approach and linked Salman's close read thread.

Did a close read of @jeremyphoward et al's Drivetrain Approach

Define goal → Consider levers → Consider data → Implement assembly line

Most important is having actions that fulfill the objective

Predictions are more data, not actions
