The document discusses how machine learning can be used to empower decision making in labour market strategy. It proposes using descriptive, predictive, and prescriptive analytics on data to provide information, insights, and recommendations to inform and communicate policy design. It also emphasizes establishing reusable analytical pipelines and experiments that can be reproduced to facilitate collaboration and reduce errors.

As a policy person
I want to find enough, relevant data that I understand and trust
so I can compare and explore by geography, time and
characteristic information to identify trends and issues to form

The importance of experiments reproducibility
“Establishing workflows that effectively allow other members of the team to reproduce our analysis
with the same data we used and obtain exactly the same results”
• Save time
• Improved collaboration
• Reduce risk of errors
