Quality is a necessary characteristic for Industrial Engineers to observe, study, and understand. Process improvements often begin at an analysis of the level of quality in a system or organization. For organizations that offer products and services to customers, a system within this company is a process that produces, maintains, or supports a product or service.
According to Kirkpatrick (1970), “a system is a physical or conceptual entity comprised of interdependent parts that interact within boundaries established to achieve some common goal or goals. “Six Sigma training provides an Outputs of systems include products, services, or components to create products and services. An example of a system would be a manufacturing line that produces the raw materials for product prototyping, or the process at a hospital that supports incoming emergency patients.
In both examples, the quality of each system can be analysed independently from its contribution to the whole facility of organization. It is important to note that this definition is universally applicable to not simply products and product design, but also service and service process design. Also, the design vulnerabilities of a product or service can either be inherit in the type of product or services being created, or perhaps established by improper conceptual design.
Regardless of which type of vulnerability may exist, the quality of a product or service is only decreased when it affects either the process that creates it by increasing costs, time, and constraints, or by affecting the end product or service that a customer uses. This implies that in sixsigma training quality is not merely achieving the perfection of a product or service, but rather, high quality is achieving perfection of product or service performance, or getting as close to it as possible.
Lean Six sigma training focus on, the quality of a product or service is determined by the individuals in the design sector. Often, decisions of product characteristics are decided by top management, and these decisions are based on their view of how well a product or service should perform, as well as what types of functionalities the product or service should have. From a total quality management perspective, the quality of a product should have many determinants, other than opinions of top management and the designer intention.
Lean Six sigma course trains the professionals in sales increases, declines, and if not corrected, can potentially lead to the termination of a product, service, or organization altogether.
While undergoing six sigma training the main focus is on a customer satisfaction perspective and an organizational ideal, rather than a simple product requirement, it can be conceptualized as a product or service characteristic that is affected by several types of organizational processes, from production processes and manufacturing concerns, to managerial implementations of quality assurance and company mind-states..
This evolution of quality as understood in Industrial Engineering disciplines has paved the way for theories and concepts such as Total Quality Management, Six Sigma, Just-In-Time (JIT), and other managerial process and quality improvement methods established around the premise of customer satisfaction by continuous quality improvements.
