Genchi Genbutsu is a principle in lean management based on direct observation and experience. In lean construction, Genchi Genbutsu is used to solve problems effectively and make informed decisions.

The main principles of Genchi Genbutsu are:

• Direct observation: Genchi Genbutsu requires decision-makers and project managers to be directly on the construction site in order to personally observe and understand problems and challenges.
• Experience-based decision-making: Decisions are based on direct experience and understanding of the real situation, rather than on theoretical assumptions or third-party reports.
• Continuous improvement: The application of Genchi Genbutsu promotes continuous improvement of construction processes through direct observation, experience, and learning.

The benefits of Genchi Genbutsu in Lean Construction include:

• Effective problem solving: By directly observing and understanding the real situation, problems can be effectively identified and solved.
• Informed decision-making: Experience-based decision-making helps to ensure that well-founded and realistic decisions are made in construction projects.
• Continuous improvement: The application of Genchi Genbutsu supports the continuous improvement of construction processes and contributes to increased efficiency and quality.
