CEMEX is a global building materials supplier with over 112 years of experience, having its headquarters in Monterrey, Mexico. The purpose of this case, based on the experiences from a cement plant in Colombia, is to provide a global view of how CEMEX’s managers carry out GEMBA WALKS in order to listen to and help their employees whenever problems arise. CEMEX started its lean journey in 2013 with the support of external consultants, with a vision to run the safest and most efficient cement operations company worldwide. Gemba walks were standardized in 2016 and they are nowadays conducted by top managers with a target of three walks per week. As a practice for continuous problem-solving, it is supported by an internal APP to collect ideas from all employees anytime, anywhere.
