The Data Science Lifecycle (CRISP-DM)
Part of the Data Science Roadmap
In short
A widely used framework — business understanding, data understanding, data preparation, modeling, evaluation, deployment — describing how a real project actually moves (with lots of looping back).
How to learn this
- 1Sketch a real or hypothetical project through all 6 CRISP-DM stages.
- 2Identify which stage usually eats the most time in practice (data preparation).
- 3Learn to budget your own project time expecting non-linear iteration, not a straight line.
