By using the values of lean construction, the preferred result would be to take full advantage of the value and productivity of a project while reducing waste and delay. This result will formed when typical construction ideas are fused with a clear understanding and brief remarks of construction project materials and data, preparation and control cost. It may appear complicated to comprehend, but the importance of lean construction system is to use what is needed without additional.

A number of researchers have investigated on the vital role of the construction sector to the overall economic growth. In Rhodes’ paper who stated the construction industry in the UK contributed £83.0 billion in economic output in 2012, which accounts for 6% of the total. Also, workforce jobs in the construction industry in UK were 2.03 million in 2012 and 2.12 million in 2013, account 6.4% and 6.5% in total respectively (C. Rhodes, 2013).

A recent report of U.S. Bureau of Economic Analysis showed that the GDP value added of construction industry was $652,723 million in 2014, 3.7% of total GDP (http://www.bea.gov/industry/gdpbyind_data.htm).

In “Lean Production in the German Automobile Industry: A Test Case for Convergence Theory”, Wolfgang Streeck seeks to analyze the degree to which the global economy drives national industries to pursue similar strategies through the case study of lean production in the German and Japanese auto industries. He accomplishes this by first defining lean production (LP) and discussing the issue of transferability before proceeding to discuss the actual auto industries themselves. While the chapter does not definitively say whether or not German companies will utilize the lean production system, it argues that doing so is unlikely as various barriers prevent complete implementation.
Companies are continually striving to increase productivity and output of their operations. Their goal is to satisfy the customer with the exact product, quality, quantity, and price in the shortest amount of time. Lean has been originally created and defined as the process of eliminating waste.

[3] A value stream is the set of processes required to transform raw materials into finished goods that customer’s value. Mapping of the value stream aids the identification of value adding and non-value adding activities. [2] Some examples are listed below:
