13 Steps to Better Data Science: A Joel Test of Data Science Maturity

Data Science teams have different levels of maturity in terms of their ways of working. In the worst case, every team member works as an individual. Results are poorly explained and impossible to reproduce. In the best case, teams reach full scientific reproducibility with simple conventions and little overhead. This leads to efficiency and confidence in results and minimal friction in productionising models. It is important to be able to measure a team’s maturity so that you can improve your ways of working and so you can attract and retain great talent. This series of questions is a Joel Test of Data Science Maturity. As with Joel’s original test for software development, all questions are a simple Yes/No and a score below 10 is cause for concern. Depressingly, many teams seem to struggle around a 3.
