In a recent post, Eugene Yan makes a blunt observation: he almost never revisits a data science project and replicates the results on the first attempt. That experience, he says, led him to adopt a set of habits designed to make follow-up easier and more reliable.
The post centers on the underappreciated value of returning to completed work. Yan suggests that without deliberate follow-up, even well-executed projects can become difficult to reproduce or build upon later. His own practice is a response to that recurring failure.
The significance lies in what it implies for data science teams: reproducibility is not a one-time achievement but an ongoing discipline. Yan's argument is a reminder that the end of a project is not the end of responsibility.
