Thank you Jeremy for such in-depth walkthrough. I'm glad you state it clearly at the end of the article about the cost of applying those 5 principles in real world projects.

May I ask you some questions?

- How to best apply those 5 principles if I don't get to work on a project from the start? I meant if the foundation of a project is quite poor.

- Do you have any article about testing ML projects?

Appreciate your time :)
