Overview/Description
Probability distributions are an essential part of descriptive statistics that Six Sigma teams can use to assist in fitting collected data into various types of distributions. Probability distributions help to ascertain specific probability values in the distribution and lead the Six Sigma teams down the hypothesis testing roadmap to the next stage of the Six Sigma DMAIC process. Of course, all this is meaningless if the data you have gathered and used is not accurate or precise, which is where measurement systems analysis (MSA) comes into play. MSA is a task in the...

Organizations need to make inferences about a population from sample data, and understanding how to calculate the probability that an event will occur is crucial to making those inferences. In a Six Sigma context, it is often important to calculate the likelihood that a combination of events or that an ordered combination of events will occur. Understanding probabilities can provide Black Belts with the tools to make predictions about events or event combinations. To make accurate inferences about a population from the sample data collected in the Measure stage, Black...

Achieving your problem-solving goals typically involves applying problem-solving skills and tools through various steps in an established problem-solving process. Whatever you think of your current problem-solving skills, it is always possible to improve upon them, and even to develop new skills. To improve, you first need to assess your existing problem-solving style, identify your strengths and weaknesses, and develop an ongoing strategy for sharpening and building your skills. You also need to recognize the key barriers that lie in the way of effective problem solving...

Norman Vincent Peale, who stressed the need for analyzing a problem at a granular level, once said, 'When a problem comes along, study it until you are completely knowledgeable. Then find that weak spot, break the problem apart, and the rest will be easy.' A fact-based, honest analysis happens at two key steps in the problem-solving process: first when you analyze problems to identify the root causes, and then, when you evaluate and analyze potential solutions to determine the one that has the maximum chance of success. Several tools are used for analysis and evaluation...

'The problem,' says author and psychiatrist Theodore Rubin, 'is not that there are problems. The problem is expecting otherwise and thinking that having problems is a problem.' A problem is a question or situation that presents doubt, perplexity, or difficulty. It's an issue that needs to be corrected or overcome in order to achieve a desired state. Problem solving involves goal-oriented thinking and action in situations for which no ready-made solutions exist. Whether consciously or unconsciously, everybody solves problems relating to their personal or work life every...

Albert Einstein is reputed to have said, "The significant problems we face cannot be solved at the same level of thinking we were at when we created them." To solve quality and process-related problems, managers should continuously enhance their knowledge of organizational processes and quality management tools. These tools help managers find root causes of problems, an important step toward removing them. Success in ensuring quality and organizational excellence depends on how effectively managers apply these tools to solve quality and process-related problems. This...

In any improvement initiative, organizations must determine whether their existing processes meet the targets and specifications demanded by the business, or by the customer. Measuring and analyzing the capability and performance of a process under review enables organizations to numerically represent and interpret its current state, and to report its sigma level. When done correctly, process capability analyses enable Black Belts to precisely assess current performance in light of future goals, and ultimately, to determine the need and targets of process improvement....
Overview/Description
To improve the processes behind an organization's products and services, a Six Sigma Black Belt must measure them. But first, they must identify those processes. Among the many Six Sigma tools, several are designed specifically to isolate relevant process variables, determine their relationships to each other, prioritize their importance relative to customer or business requirements, and assess their efficiency. Using SIPOC and cause-and-effect matrices, Black Belts can determine which process inputs to target first â those with the most significant impact on important...

A process is a means of creating and delivering products and services needed by customers. According to Takashi Osada, Japanese author and quality pioneer, "if the process is right, the results will take care of themselves." By Six Sigma standards, a "right process" is one that creates and delivers precisely what the customer needs. By this logic, no Six Sigma effort can start without having a high-level picture of an organization's customers and other stakeholders, their needs, and the business processes meant to fulfill those needs. A thorough analysis of the existing...

Why can some people walk into a room and start making new acquaintances almost immediately? It's as if they're hardwired to know how to introduce themselves and establish a relationship with everyone they meet. Wouldn't it be great to have that kind of finesse with people and be able to network with ease? The reality is that while networking may seem intimidating or awkward at first, it's becoming a 'must have' for many in the modern professional environment. It requires confidence and sincerity. This course helps you develop that confidence by exploring the obstacles...
