Obeya is a lean management concept that provides a space for collaboration, decision-making, and problem-solving. In lean construction, Obeya is used to promote communication and collaboration within the project team and increase the efficiency of construction projects.

The main principles of Obeya are:

• Collaboration: Obeya promotes collaboration between different functions and departments within the project team to enable effective problem solving and decision making.
• Transparency: In the Obeya room, information, progress, and challenges are openly shared to ensure transparent communication and rapid decision-making.
• Continuous improvement: The use of Obeya supports the continuous improvement of construction processes through collaboration, transparent communication, and joint problem solving.

The advantages of Obeya in lean construction include:

• Improved communication and collaboration: Obeya promotes communication and collaboration within the project team, leading to greater efficiency and quality in construction projects.
• Faster decision-making: Transparent communication and joint problem solving in the Obeya room enable decisions to be made more quickly.
• Continuous improvement: The use of Obeya supports the continuous improvement of construction processes through collaboration, transparent communication, and joint problem solving.
