A Correlation Coefficient is a statistical concept expressed as the letter “r” that measures the strength and type of the relationship between two factors (‘X’ and ‘Y’). A Correlation Coefficient is a number between -1 and +1. An ‘r’ of +1 means that there is a perfect, positive correlation between…
Cost/Benefit Analysis is a decision-making tool to compare costs (negative results) vs. benefits (positive results) of a proposed change to a process. The costs can include labor, equipment, materials and time, and the benefits often include increased customer satisfaction, increased revenue, cost avoidance and reduced cycle time. For a better…
The Control Phase is the last phase of DMAIC, and ensures that improved processes continue to work predictably and meet the customers’ expectations. In short, Control ensures any gains are maintained. During this phase the documentation is finalized, monitoring plans are put into place and response plans are designed in…
Continuous Improvement broadly describes ongoing, incremental efforts to improve products and processes. Continuous Improvement with Lean Six Sigma utilizes a data-driven approach and process analysis to solve problems. For a better understanding of Continuous Improvement and an overview of Lean Six Sigma, check out our Free Lean Six Sigma Yellow Belt…
Continuous Data refers to data that is measured on a continuum. It is data that is measured on an infinitely divisible scale (e.g., time, weight, and temperature) such that one half a unit still makes sense; half a minute, half a pound, etc. A defining characteristic of continuous data is…
Contingent Actions are pre-planned steps scheduled to go into effect when defects or failures occur. They are designed to minimize damage and cost due to failures. For a better understanding of Contingent Actions and an overview of Lean Six Sigma, check out our Free Lean Six Sigma Yellow Belt Training, Green…
Comparative Analysis is a form of deductive logic that makes an item-by-item comparison using data and facts. This method is most useful when two similar processes yield significantly different results. Comparative analysis is a low impact, low effort way of discovering the elements within the processes that are responsible for…
Common Cause Variation is a type of variation which is natural and inherent to a process. Common Causes act randomly and independently of each other, are difficult to eliminate, and often require changes to a process or system. The output of Common Cause variation generally conforms to a normal distribution…
A Cockpit Chart is a high level, at-a-glance display of key performance indicators that are regularly monitored. Ideal for presenting to process owners, senior leadership and stakeholders, Cockpit Charts vary in composition but typically measure the performance of Processes, People, Innovation, and Finance. For a better understanding of the Cockpit…
A Master Black Belt (aka a Coach) is the highest level of training for a Six Sigma practitioner. Master Black Belts not only guide improvement teams, but are responsible for identifying improvement projects. For a better understanding of the Master Black Belt and an overview of Lean Six Sigma, check out…
