Abstract: Release train formation, as part of SAFe transformation proceeded by forming a SAFe pilot with teams that already had experience with agile practices. Success of pilot led to launching of new release trains. The forming of new trains was challenged with: politics, difficulties in identifying value streams and, not wanting a radical restructuring of the organisation. These challenges led to opting for an organic way of transformation. Next, management organized several workshops to identify stakeholders for the second train. This was followed by teams choosing their teams based on skills and interests. And the last two trains were formed using lego workshops. The most significant challenges of forming release trains were: struggles with projects and challenges due to dependencies.
