Process Capability Indices (PCI) are among the most important quality measurement tools for the Continuous Improvement of quality and Six Sigma Program (Arcidiacono, Costantino, and Yang 2016). For instance, pointed out that the proper use of Capability Indices can improve process control performance, they can evaluate the relative process performance and can compare one material or supplier with others. A process is a unique combination of tools, materials, methods, and people engaged in producing a measurable output (Duncan 1986).
Statistical Process Control (SPC) is a methodology that was first developed by Walter Shewhart (Shewhart 1986) to measure quality and variability during a manufacturing process. Every process reveals variation of two kinds: “common cause” variation, natural and controlled; “special cause” variation, uncommon or unstable (Chiu and Wetherill 1975; Montgomery 2013). It is now generally agreed that the SPC regime is implemented in two phases or stages in practice: Phase I, the so-called retrospective phase, and Phase II, the prospective or monitoring phase. In Phase I, the primary interest is to better understand the process and assess process stability; the latter often consists of trying to bring a process in control by analyzing historical or preliminary

It compares the output of a stable process to the specification limits by using Capability Indices and it is a measurement with respect to inherent precision of a manufacturing process. Process Capability can be assessed through the computations of various Process Capability ratios and indices. Process Capability Indices are intended to provide single number assessment of the ability of the process to meet specification limits on quality characteristics of interest. Thus, it identifies opportunities for improving quality and operational performance (Liu and Chen
Even though I have no real experience in software development I know that dealing with software is not easy and can be very frustrating. Six sigma incorporates many tools that help organizations determine their customer requirements. Before reading this article I thought six sigma was just about statistics and improving processes. It is so much more than that. It’s also about managing all given information or data quantitative or not. Six sigma can help with customer requirements and also with understanding processes capability.
Initial understanding of a process excellence team is an important foundation for understanding this specific team collaboration. Process excellence as described by Carter (2010) is a “Six Sigma process …used to eliminate defects and inefficiencies in a process or service.” In healthcare, our business is patient satisfaction. “Six Sigma” (Carter, 2010) is a team process that utilizes an approach to effectively control ...
In today's competitive marketplace, all firms are seeking ways to improve their overall performance. One such method of improvement, recently adopted by many firms, is benchmarking. Benchmarking is a technique used to evaluate internal business processes. "In this analysis, managers determine the firm's critical processes and outputs, baseline those processes, then compare the performance of each process against a standard outside the industry" (Bounds, Yorks, Adams, & Ranney 1994). To effectively improve a business process to world-class quality, managers must find a firm that is recognized as a global leader, not just the industry standard. Successful benchmarking requires tailor-made solutions, not just blind copying of another organization. Measurement and interpretation of data collected is the key to creating business process solutions.

Basically, the focus of the recommendations is to reduce the disparities between the capacities of the processes involved. Ideally, their outputs must be equal if not, similar to the preceding and succeeding procedures in order to achieve an efficient manufacturing process.
The Six Sigma approach was designed by Motorola in 1986. The primary objective of the concept was to develop a tool for tallying the process defects and, as the result, improving business operations. The foundations of the approach are the customer needs, statistical analysis of data and facts, and timely execution. The method promises numerous benefits such as increasing performance and profitability of an organization, improving product or service quality and employee morale, decreasing costs, the growth of market share, the higher level of satisfying customer needs, etc. (Meredith & Shafer, 2013). The primary advantage
During this project, I am going to mention the details of TOYOTA production process system which was developed more than 40 years ago by Taiichi Ohno, the president of Toyota Motor company at that time. The production system that Toyota company uses now and before is relevant to the concept of the process costing system which is currently used in all department of the company.
Business improvement techniques such as Six Sigma, Lean Management, Theory of Constraints (TOC) and Continuous Process Improvement (CPI) are successful and accepted worldwide. Many successful firms, for instance Toyota uses production planning techniques to achieve world class quality output. AGI in this paper illustrates the before and after stages by implementing various business improvement techniques to achieve the desired output. Also, high end business such as, U.S Navy implements the integrated blend of TOC, Lean and Six Sigma approach- “AIR” to eliminate the problems arising from uncertainty and inefficiency. Furthermore adding speed and direction to their project. On the other hand, Youngman demonstrates the production planning using
The report highlight’s the essential aspects of the control process. In terms of concurrent feedback as well as feed forward, that companies can use to implement so that they can have better outcomes in terms of efficiency of the business. Consequently the report underlines as well as emphasizes of the many contributing factors of these controls. The authors have contrasting views on the control models of an organization, they believe that in order to create an effective control process, and organization first needs to determine its strategic plans for instance in terms of what it is and where is it going.
The development of the manufacturing industry, quality and control, manufacturing capacity increase or the duration and the need to reduce cost has arisen is inevitable. Thus automation and programming concepts were started years ago. Automation is a machine's operative procedures and their sequence start form beginnig to end without human intervention, and its done automatically. Programming of the sequence of operations is prerared and tranfered to the counter. A bench during the operation of the program, and in the process, this will provide for amendments to the alignment and speed, then the counter is called flexibility.
In past few years, companies and industries of various sizes have become aware that they need to improve business processes such as product development, order fulfilment, planning, distribution, and customer service. So everybody is now focusing on doing process improvement or redesigning.
The process control is a method to control, prevent and make better the process functionality of the companies. The advantage of the process control is detect early and prevent the problems and achieves goals to make the future better for customers, employees, partners, etc.
Firstly, there is a need to focus on the company competitive dimensions before embarking on the decisions. In this aspect, the Competitive capabilities are the Cost, Quality, Time, and Flexibility dimensions that a process or value chain actually processes and is able to...
Manufacturing Execution: consistency on manufacturing throughput the cycle of production with different execution capabilities to ensure maximize production flexibility, improve execution process and increase efficiency of the plant by planning and management of inventory.
Improvement in the quality is a continuous process; by discontinuing the continuity will shatter the business competitiveness in the market. Generally, six sigma, lean and Kaizen are being used for continuous improvement by the companies. But in case of manufacturing companies, they need to be more calculative and carful in the continuous improvement is essential but the company should be cautious in not investing in destructive research. It is not possible for implementing the TQM in all process (Ashkenas, 2013).
