Gemba is a management practice based on the Japanese philosophy of "go and see." It involves leaders and managers physically observing and interacting with employees in their actual work environment, rather than relying on assumptions. This allows them to grasp the current situation and identify problems and opportunities for improvement. The focus is on processes, not people, and it is not meant to be a performance evaluation. Gemba walks are an essential part of the Lean management philosophy and can help track value creation and flow, as well as promote continuous improvement. The purpose of a Gemba walk is to observe, understand, and take action to improve processes, and it provides a valuable opportunity for staff to step back from their daily tasks and identify wasteful activities.
