1. Eliminate waste: Waste is one of the major problems in the production process of real estate companies. The goal of lean manufacturing is to eliminate these wastes, including overproduction, inventory, transportation, and waiting time. By reducing or eliminating these wastes, companies can significantly improve efficiency.

2. Optimize processes: Housing companies can improve efficiency by optimizing production processes. This includes reducing the number of production steps, optimizing design, and reducing unnecessary steps. By optimizing processes, companies can reduce the waste of time and resources and increase productivity.

3. Use of advanced technology: with the development of science and technology, advanced technology has also been applied in the real estate field. For example, the application of technologies such as IoT, artificial intelligence, and big data can help real estate companies better manage their projects and improve efficiency.

4. Employee training: Lean manufacturing emphasizes the human factor. Therefore, real estate companies need to train their employees to understand the concepts and methods of lean production and be able to apply them in their actual work. Through training, companies can improve the skills and efficiency of their employees and further promote the realization of lean production.

5. Continuous improvement: Continuous improvement is one of the core concepts of lean manufacturing. Real estate companies need to constantly look for opportunities for improvement, including process improvement, technological innovation and so on. Through continuous improvement, companies can continuously improve efficiency and reduce costs.
