The Agile Yorkshire Xmas Lightning Talks Competition in 2015 was filled with eight incredible speakers, each delivering a fast-paced 10-minute talk on exciting and engaging tech topics. With audience voting and a strict schedule, the event was a fun and educational experience. This video, filmed at the 2015 event, highlights one of the exciting presentations from the evening. Enjoy watching the talk! In this talk, Susanna discusses her experience managing the transition from Waterfall to Agile Scrum at ASDA and the resistance teams often face. She explains that the challenge lies not only in the methodology but in changing deeply ingrained mindsets and culture. Using a riverbed metaphor, Susanna highlights how difficult it is to change a company's culture. She shares practical steps ASDA took to tackle resistance, such as securing leadership support, offering education, and creating communities of practice for team members to discuss concerns and share success stories. Susanna stresses that resistance should be seen as an opportunity for growth, with a supportive approach being key to a successful Agile transformation.
