This is the meta case study for The Turing Way Practitioners Hub's Cohort 1 - Case Study Series publishedonline under the CC-CY 4.0 license. The Practitioners Hub is a The Turing Way project that works with experts from partnering organisations to promote data science best practices. For more information about the Practitioners Hub, please visit our website: https://www.turing.ac.uk/turing-way-practitioners-hub. This meta-case study, drawing key lessons from five case studies published by the first cohort of EiRs. This case study provides an overview of common understanding, challenges, successful examples, and trends related to best practices, specifically in open source, open data, and collaboration across different sectors. This work is supported by Innovate UKBridgeAI.

The inaugural cohort of The Turing Way Practitioners Hub has been designed and led by Dr MalvikaSharan. The Research Project Manager is Alexandra Araujo Alvarez. Stuart Gillespie is the technicalwriter for this case study, and others in the series. Led by Dr. Kirstie Whitaker, Programme Director ofthe Tools, Practices, and Systems research program, The Turing Way was launched in 2019. The TuringWay Practitioners Hub, established in 2023, aims to accelerate the adoption of best practices. Througha six-month cohort-based program, the Hub facilitates knowledge sharing, skill exchange, case study co-creation, and the adoption of open science practices. It also fosters a network of ’Experts in Residence’across partnering organisations. For any comments, questions or collaboration with The Turing Way, pleaseemail: turingway@turing.ac.uk.
