In Lean construction, "Gemba" refers to the place where work happens—where value is created. The term comes from the Japanese word meaning "the real place," and in construction, this often means the job site or any location where tasks directly contribute to project outcomes.

A Gemba walk involves physically visiting this space to observe the processes, understand the workflow, and identify opportunities to eliminate waste. The goal is not to critique individuals but to evaluate the system and processes that drive the work.

The Purpose of Gemba

The primary purpose of a Gemba walk is to gain firsthand insight into how work is being done, ensuring that all tasks align with project goals and contribute value. It’s an opportunity to:

• Identify inefficiencies or bottlenecks in the workflow.

• Observe how well resources are being utilized.

• Engage with the team to gain a clearer understanding of their challenges and ideas for improvement.

How Gemba Supports Lean Principles
