Abstract
LEGO® SERIOUS PLAY® (LSP) is an effective methodology to enable the representation of abstract concepts and has been applied to teach several Software Engineering topics. However, there is limited evidence on how LSP can be used in training on agile mindset, which is the core and central element of agile methods. This paper demonstrates how LSP can be utilized in agile training to reveal the agile mindset of participants. We describe our experience of utilising LSP in an agile training project for local software companies. Since the project was run during the COVID-19 pandemic, we adapted the LSP methodology for online settings, which was not straightforward because face-to-face interactions and tangible objects are key characteristics of LSP. In this experience report, we describe the design of the online LSP workshops and explain how to analyze LSP models to reveal the agile mindset of the participants and to tailor the training accordingly. We also provide evidence of the effectiveness of the LSP methodology in our training project. Drawing upon our experience, we synthesize a set of lessons learned and sketch recommendations for educators who intend to apply LSP in their future endeavours.
