B. Overview of Lean Management
The lean management principle was first developed by Japanese production industries (Toyota Car Company).It was executed by a discoverer named John Krafcik in the year 1988.
C. Lean Construction
According to Koskela and Thomas et al. [4], Lean construction includes practice of just-in-time, use of pull-driven arrangement, reduction of variability in labour productivity, improvement of flow dependability, removal of waste, overview of the operation, and implementation of benchmarking.
D. Waste Elimination
Waste elimination is very significant process in the construction sector to improve the quality and productivity of the project. Waste may be generated directly or indirectly during the construction in the construction industry.
III. LITERATURE
Lean is best defined as “a systematic approach to identifying and eliminating waste (non-value added activities) through continuous improvement by flowing the product only when the customer needs it (called pull) in pursuit of perfection” (Sarkar, 2008, p. 1). Lean thinking along with Six Sigma have generated interest all industries. This can be seen by the countless studies and quality improvement efforts undertaken by many corporations, with training and building staff as certified Lean Six Sigma experts.
Lean manufacturing refers to systematic identification and elimination of waste through CI processes in pursuit of perfection (Khan et al. 2013; Yang & Yang 2013). Lean production is now used worldwide in manufacturing plants to eliminate waste from all ar...
With the disposal of solid waste from process, manufacturing and its waste pose considerable challenges for many organizations. Since, landfilling has become limited, and with the cost of waste disposal continuing to rise, they needed alternative measures.
Waste management is the operation of how waste materials are handled. The affair of waste management is relevant to everyone world-wide. Wastes are materials that have no further economic use, and when disposed of, are hazardous to humans and the environment. Wastes include solid waste, liquid wastes, and air pollutants created by humans and cannot be naturally recycled. Current waste management techniques need to be completely overhauled because funding in government budget is not enough to meet standards, landfills are reaching their maximum capacity worldwide, and nuclear waste storage must be handled correctly. Waste management has been a highly thought about complication for global authorities. Due to
Lean Six Sigma is a methodology that creates processes within an organization to cut waste and improve the company’s performance. However, studies have shown that over the past decade applying Lean Manufacturing and Six Sigma can create problems for companies financially and potential problems for employees. Companies should take great care before implementing a Lean Six Sigma solution because in some instances, going lean can do more harm than good both financially for the organization as well as destroying employee loyalty and moral.
The raw materials are then sent to the production shop to be processed in large containers and under certain conditions for product manufacturing. At this stage of the production cycle, high amounts of energy and water are consumed and wastes are generated. Most of the companies in the industry are aiming to reduce the consumption of energy and water, and production of waste with their sustainability programmes and
Therefore, Henry Ford with some other engineers invented some theories that could help eliminate waste during production. In addition to this, other theories and developments such as the study of time, standardize work and the elimination of non-value added activities were also invented and applied to the Toyota production system. This proves that lean concept began from Craft Production through to Mass Production and finally
Achieving quality of conformance involved conform to specifications that involve providing customers with a quality product at the right price which accounts for the cost of materials. In order for a company to achieve and produce a successful product that customers want and need, it is vital that quality management and lean systems play front row. Quality management helps organizations to reduce waste and inventory. “Lean is about challenging the way things are done and opening our eyes to that waste and inefficiency” (Lean Benefits - Benefits of Lean, Why Lean is Important, 2015). Within each of these concepts are important tool and techniques that organizations can use to achieve a quality product. In this paper I will discuss “cost of quality” from the quality management side and “kaizen’s” from the lean system side, while discussing how each of these concepts are implemented into my own life or
With the aid of study that reports obstacles and issues associated with implementation of LPS on a construction project.

Elimination of waste in business practices is an important part of Kaizen. Waste is any activity which raises costs without adding value to a product. Waste could be time wasted while staff waits before starting their tasks; time wasted when workers move unnecessarily in the workplace; the irregular use of a machine.
The main idea is to fulfill the internal or external customer’s wants. Through lean thinking, it is hoping that nonmanufacturing company’s can provides value to the customers with minimum cost, effort and can save time. Thus, it will lead to improve performance and optimum utilization of the company’s additional capacity and resources.
