Lean Construction And The Construction Process

Lean manufacturing is the production of goods using less of everything than in mass production: less human effort, less manufacturing space, less investment tools and less engineering time to develop a new product. A company becomes lean by continuously increasing its capacity to produce high-quality goods while simultaneously decreasing

Production practices have had an important role in satisfying the dynamic market. Many approaches have being developed in order to respond effectively to specific business requirements. In fact, some areas of management have focused its study on the overseeing, designing, and controlling the process of production in an effort to find the best methodology that ensures the business success and performance. However, complexities arise in this field because many variables such as costs, inventory, scheduling, suppliers, etc have to be considered in any business. Lean approach and the traditional approach are two points of view that aim to address this complexities, and those will be examined in this essay.

“Lean is a systematic approach to identifying and eliminating waste (non-value-added activities) through continuous improvement by flowing the **product at the pull of the customer in pursuit of perfection.” Lockwood [24].

Lean operations emphasizes the understanding of the customer by producing units only as they are needed. As individual units are manufactured this reduces inventory drastically. This also would reduce any waste of products created and not sold. Both of these processes would have been a benefit to my company as there were several units of certain brands that were not desirable or meeting customer needs. This caused a loss of revenue by having units that were produced but not sold. The lean operations and Just In Time methods would eliminate this problem from the manufacturing side of my company.

The advantages of lean operations are that they cut costs, save time, and are easy to monitor. The disadvantages are difficult implementation.

Overall, the purpose of lean is to improve processes. Lean is not a methodology that seeks for the reduction of costs, even though it might appear as a result of a great implementation of Lean. Neither is a methodology to improve productivity, as it might require to do more work that do not necessarily means that the staff is doing the right things. Lastly, Lean is not about restructuring the work the staff do, as it might simply mean changing activities without considering if they are actually value added or not.

Lean production is an incorporated group of activities set up to attain high volume production by using low inventories of raw materials, processing goods, and finished goods (Chase, Jacobs, & Aquilano, 2006). Using a lean production process, the China plant will be able to produce goods at a lower cost. Riordan China plant will need to eliminate any waste in the production process to achieve the highest level of efficiency.

“Lean means creating more value for customers with less” (Krejewski, L., Ritzman, L.P., & Malhotra, M.K., 2013). Implementing this into a project can make the project very successful at a lower rate of cost and time. There are five steps in allowing the lean process to work successfully. This process is easy to remember but not always easy to achieve. Specifying the value from the customer’s point of view of the product that the customer is interested in purchasing is the first step. Identifying all the steps of value for the product the customer wants to purchase and eliminating the steps that are unnecessary is the second step. Creating a sequence of steps that flow in a consistent fashion and will flow smoothly toward the customer is the third step. Introducing the flow of the product that the customer is interested in purchasing and allowing the customer to pull value from the product is the fourth step. The fifth and final step in the lean technique process is “as value is specified, value streams are identified, wasted steps are removed, and flow and pull are introduced, begin the process again and continue it until a state of perfection is reached in which perfect value is created with no waste” (Lean Enterprises Institute, 2015).

Lean Manufacturing system pursues optimum streamlining throughout the entire system by the elimination of waste (non-value added/ waste) and aims to build quality into the process while recognizing the importance of cost reduction.

History above shows growth. Switchgear market is fully developed see exhibit 4. Customer orders increased by 75% and expected to keep rising. Lean implementation is needed to meet demand utilizing existing capacity to improve financial performance for the factories. The order follows the route see exhibit 5. Each department fulfils its responsibilities before passing on to the next. Lean started with meetings between management and lean team explaining its benefits in response to panels demand rise. Layout and processes were restructured. Mapping process was done. Lean team held discussions with every department in value chain to understand the current working process. Brainstorming and awareness sessions were done resulting in process flow chart that changes the way

The application and implementation of lean principles or thinking is a process that requires commitment from every stakeholder in the organization. This process entails commitment to the organization's workers and to the system itself in order to make changes towards improvement. Generally, the implementation of lean thinking is geared towards continuous improvement through the elimination of waste. However, lean management or implementation of the principles sometimes incorporate mistakes that are made by leaders in the execution process. This is mainly because lean leadership appears to be simple though its complex because of the costs associated with it. The mistakes usually occur because of intrinsic complexities of exploring deeply into organizational philosophies, business strategy, psychology, and macroeconomics.

According to the collected data and the relations associated with involved components, the researcher summarizes the beneficence and contribution of IPD, Lean principles, and BIM in the conceptual model. In order to establish a powerful checklist for construction projects that expect to apply all remarkable characteristics of each element in ILB’s collaboration, six prime measures are evaluated and considered for the common synergies. As a result, the summary is represented in Table 5.2.

Lean is defines the manufacturing philosophy that reduces the time between the shipping and customer demand, which based on the systematic method by eliminating waste, that means giving the customer what they want when they want it, and don 't waste whatever. Rahmana, Sharif and Esa (2013) suggested lean production is mentioned to improve the company 's performance from the philosophy in reducing waste in order. That means, lean system destination is the decrease cost by removing the non-value activities, which they are applying a category of tools and techniques for checking and eliminating defective in the production process. In the Evenort Company should emulate the five overriding principles of lean thinking in terms of implementing lean that there is guarantee the company has been driving correctly in the lean manufacturing (Cardiff 2015) as can show in table 1.

Lean is a process where creating more value to customers by minimizing wastage, time with less resources. Lean organization understand the customer value and try to increase proceed which adding more value to the business. In order to accomplish the lean thinking
