In the Define phase of a Lean Six Sigma project, the primary focus is on defining the problem, objectives, and scope of the project. The identification of root causes typically occurs in the Analyze phase of the DMAIC (Define, Measure, Analyze, Improve, Control) methodology.
In a hypothesis test, a Type I error is typically associated with a "False Positive."
Type I error, also known as alpha error or producer's risk, occurs when the null hypothesis is incorrectly rejected when it is actually true. In other words, it is the probability of concluding that there is a significant effect or difference when, in reality, there is no such effect or difference in the population being studied.
The name of an approved written plan outlining the expected benefits to the business and the anticipated savings from running a Lean Six Sigma project is called a Project Business Case.
The Project Business Case is an essential document used in the early stages of a Lean Six Sigma project, particularly during the Define phase of the DMAIC (Define, Measure, Analyze, Improve, Control) methodology. It serves as a justification and proposal for undertaking the project, providing a clear rationale for investing time, resources, and effort into the improvement initiative.
The term "Blocks" usually refers to a specific technique used in regression models, such as "Blocked Multiple Regression" or "Hierarchical Regression," where the independent variables are divided into blocks or subsets and are entered into the model in a specific order. Since you requested to exclude "Blocks," I have not included that in the list of components.
Value Stream Mapping (VSM) is a technique that is considered to be part of the toolkit from Lean methodology.
Value Stream Mapping is a powerful visual tool used in Lean management for analyzing and improving the flow of materials and information within a process or across an entire value stream. The value stream represents all the activities and steps required to deliver a product or service to the customer, from the raw materials to the final product.
Benchmarking is the technique used by a company to measure its performance against that of best-in-class companies or industry leaders. It involves comparing various aspects of a company's processes, practices, and performance metrics to those of top-performing organizations or competitors with the aim of identifying opportunities for improvement and best practices.
A product or service that does not meet the expectations of the customer is often referred to as a defective product or service.
The Lean Six Sigma concept of 'Critical to Quality' (CTQ) always focuses on meeting the specific requirements of the customer.
In Lean Six Sigma, the term CTQ refers to the key characteristics or attributes of a product, service, or process that are critical in meeting the needs and expectations of the customer. These CTQs are the factors that have a direct impact on customer satisfaction and are considered vital for the success of the project or improvement initiative.
In a designed experiment, an input variable is often referred to as an experimental factor.
Standard Operating Instructions (SOIs) and Visual Management are highly applicable tools for a work team to use when there is a need to follow procedures and work instructions more closely.
Long-term process variation contains all forms of variation in the process, while short-term process variation only includes the variation that occurs within a specific subgroup or batch of data.
Both Full Factorial and Fractional Factorial Designs are valuable tools in experimental design and hypothesis testing. They allow researchers and engineers to efficiently explore and understand the relationships between factors and responses in a systematic manner. By using DOE designs, organizations can optimize processes, improve product designs, and make data-driven decisions to achieve better quality and performance. The choice between Full Factorial and Fractional Factorial depends on the specific objectives of the study, available resources, and the complexity of the factors involved.
Understanding "the voice of the customer" (VOC) is a fundamental technique used in quality management and customer-centric approaches, such as Lean and Six Sigma, to provide customers with services and products that meet their expectations and needs.
"The voice of the customer" refers to the process of gathering and understanding the specific requirements, expectations, preferences, and feedback of customers regarding a product, service, or process. By actively listening to and analyzing customer feedback, organizations can gain valuable insights into what customers truly value and desire.
The 5S Lean Six Sigma tool is used to organize and create order in the layout of tools and equipment in the workplace. It is a foundational technique in Lean management and plays a crucial role in improving workplace efficiency, safety, and overall productivity.
A regression equation describes the relationship between a response variable (Y) and one or more predictor variables (X). The equation represents the mathematical model that estimates how changes in the predictor variables are associated with changes in the response variable.
Understanding who the customer is in a process is a fundamental aspect of quality management and process improvement. The best definition of "The Customer" is anyone who receives a product or service from the process or could potentially receive a product or service from the process.
