The purpose of this paper is to test the reliability and validity of the qualitative section of Lean Assessment Tool LAT starting from the point where a reliable and valid tool is needed to measure increasing leanness level of business organizations. The questionnaire used in this study included the qualitative component of LAT developed by Pakdil and Leonard The unit of the study was individual employees who work in manufacturing firms participating in this study.
This study focused on the data collected from three firms that operate in Turkey and two firms that operate in the USA.
The total respondents from Turkish firms were employees, while the employees responded from US firms. The statistical analysis showed five distinct factors, namely process, delivery, quality, customer satisfaction and human resource. In addition, the fuzzy logic showed appropriate loadings to make the argument for its use in analysis of the LAT.
This study moves the debate about the success or failure of lean efforts forward. With the debates about lean and its potential, it is necessary to have a scientific determination of success and the areas where further work in the firm is needed. Such measurement is the backbone of management progress, and the authors believe that this paper is useful. This places huge importance upon sponsorship to encourage and protect these experimental developments. Lean management is nowadays implemented also in non-manufacturing processes and administrative processes.
In non-manufacturing processes is still huge potential for optimization and efficiency increase. The espoused goals of lean manufacturing systems differ between various authors. While some maintain an internal focus, e. Some commonly mentioned goals are: [ citation needed ]. The strategic elements of lean can be quite complex, and comprise multiple elements.
Four different notions of lean have been identified: . Lean production has been adopted into other industries to promote productivity and efficiency in an ever changing market. In global supply chain and outsource scale, Information Technology is necessary and can deal with most of hard lean practices to synchronise pull system in supply chains and value system. The manufacturing industry can renew and change strategy of production just in time. For instance, Dell sells computers directly from their website, cutting franchised dealers out of their supply chains.
Then, the firm use outsourced partners to produce its components, deliver components to their assembly plants on these main markets around the world, like America and China. Zara made decision of speeding their fashion to the consumers market by fast-producing cloths within five weeks with their local partners in Spain and never involved in mass production to pursue new styles and keep products fresh.
The other way to avoid market risk and control the supply efficiently is to cut down in stock. With the improvement of global scale supply chains, firms apply lean practices JIT, supplier partnership, and customer involvement built between global firms and suppliers intensively to connect with consumers markets efficiently. James Womack had warned Toyota that cooperating with single outsourced suppliers might bring unexpected problems.
The following steps should be implemented to create the ideal lean manufacturing system: . A fundamental principle of lean manufacturing is demand-based flow manufacturing. In this type of production setting, inventory is only pulled through each production center when it is needed to meet a customer's order.
The benefits of this goal include: . A continuous improvement mindset is essential to reach the company's goals. The term "continuous improvement" means incremental improvement of products, processes, or services over time, with the goal of reducing waste to improve workplace functionality, customer service, or product performance.
Lean is founded on the concept of continuous and incremental improvements on product and process while eliminating redundant activities. Overall equipment effectiveness OEE is a set of performance metrics that fit well in a lean environment. Also, PMTS, methods-time measurement, cost analysis and perhaps time study can be used to evaluate the wastes and IT effectiveness in the operational processes.
For example, Jun-Ing Ker and Yichuan Wang analyze two prescribing technologies, namely no carbon required NCR and digital scanning technologies to quantify the advantages of the medication ordering, transcribing, and dispensing process in a multi-hospital health system. With comparison between these two technologies, the statistical analysis results show a significant reduction on process times by adopting digital scanning technology. The results indicated a reduction of One criticism of lean is that its practitioners may focus on tools and methodologies rather than on the philosophy and culture of lean.
Consequently, adequate management is needed in order to avoid failed implementation of lean methodologies. As a result, lean implementations often look good to the manager but fail to improve the situation. In addition, many of the popular lean initiatives, coming from the TPS, are solutions to specific problems that Toyota was facing.
Validation of qualitative aspects of the Lean Assessment Tool (LAT)
Toyota, having an undesired current condition, determined what the end state would look like. Through much study, the gap was closed, which resulted in many of the tools in place today. Often, when a tool is implemented outside of TPS, a company believes that the solution lay specifically within one of the popular lean initiatives. The tools which were the solution to a specific problem for a specific company may not be able to be applied in exactly the same manner as designed. Thus, the solution does not fit the problem and a temporary solution is created vs.
The lean philosophy aims to reduce costs while optimizing and improving performance. Value stream mapping VSM and 5S are the most common approaches companies take on their first steps towards making their organisation leaner. Lean actions can be focused on the specific logistics processes, or cover the entire supply chain. For example, you might start from analysis of SKUs stock keeping units , using several days to identify and draw each SKUs path, evaluating all the participants from material suppliers to the consumer.

Conducting a gap analysis determines the company's 'must take' steps to improve the value stream and achieve the objective. Based on that evaluation, the improvement group conducts the failure mode effects analysis FMEA , in order to identify and prevent risk factors. It is crucial for front-line workers to be involved in VSM activities since they understood the process and can directly increase the efficiency. Although the impact may be small and limited for each lean activity, implementing a series small improvements incrementally along the supply chain can bring forth enhanced productivity.
After adopting the lean approach, both managers and employees experience change. Therefore, decisive leaders are needed when starting on a lean journey. There are several requirements to control the lean journey. First and most importantly, experts recommend that the organization have its own lean plan, developed by the lean Leadership.

In other words, the lean team provides suggestions for the leader who then makes the actual decisions about what to implement. Second, coaching is recommended when the organization starts off on its lean journey. They will impart their knowledge and skills to shopfloor staff and the lean implementation will be much more efficient.
Third, the metrics or measurements used for measuring lean and improvements are extremely important. It will enable collection of the data required for informed decision-making by a leader. One cannot successfully implement lean without sufficient aptitude at measuring the process and outputs. To control and improve results going forward, one must see and measure, i. Lean manufacturing is different from lean enterprise. Recent research reports the existence of several lean manufacturing processes but of few lean enterprises. For standard cost accounting, SKUs are difficult to grasp.
SKUs include too much hypothesis and variance, i. Manufacturing may want to consider moving away from traditional accounting and adopting lean accounting. In using lean accounting, one expected gain is activity-based cost visibility, i. From Wikipedia, the free encyclopedia. This article has multiple issues.
