What do you understand by Theory of Constraints (ToC)? The Theory of Constraints (TOC) is a management approach to managing the weakest link in a process. A process can have one or more weak links, called constraints, that can be anything that prevents the process from performing to its maximum potential. TOC contends that a […]

Selecting the Right Sampling Method for LSS Projects There are different reasons why you would go for sampling.If you are a Lean Six Sigma Green Belt or Lean Six Sigma Black Belt, or just an aspirant or a Quality Engineer, you will encounter several scenarios where you have to sample the data during data collection […]

Cpm is yet another interesting process capability metric that is not very popular. In fact it is more robust than Cpk. Cpm is an advanced measure and it corrects some deficiencies in Cpk. It is also called as Taguchi Capability Measure. In order for us to understand Cpm, let’s take a step back and understand Cpk. […]

I’m sure you have heard of ‘Python’ in the context of Data Science and Analytics. Python is an object oriented high-level programming language with built-in data structures. If you are already a Certified Green Belt or a Black Belt from ASQ, IASSC or any other certification body, you might be familiar with a variety of […]

Any aspirant preparing for Lean Six Sigma Certification Exams of ASQ or IASSC, it is important for you to understand the difference between CTQ, Primary Metric and Secondary Metric.In Lean Six Sigma, the term CTQ is very commonly used. CTQ is an acronym Critical to Quality. As the name suggests, any attribute, parameter, factor or […]

Both DFMEA and PFMEA have similar principles and follow identical steps. Both involve identifying potential failures, their impact, and corrective measures to be taken for reducing or eliminating these potential failures. However, DFMEA and PFMEA differ in a few aspects, such as their focus and the stage in which these two analyses are done. DFMEA […]

Fig: A Y-shaped matrix that summarizes the requirements for different models of photocopiers The Y-shaped matrix is a matrix diagram that relates three sets of elements where one set is related to the other two sets in a circular manner. . It can be formed by bending the columns of sets A and B in […]

Matrix diagrams can be sorted into several types depending on the number of data sets being compared. L-shaped Relates two sets of elements to one another or a single set of elements to itself. T-shaped Relates three sets of elements where there is no relation between the two sets that are related to a common […]

A matrix diagram, also called a matrix chart, is a management and planning tool used for identifying relationships between two to four groups of elements or among elements in a single group. The elements in different groups are placed in rows and columns and relationships among them are analyzed by the team. Symbols indicating the […]

In the previous topic, you created a tree diagram. Key issues identified must also be sorted in the order of their importance. A prioritization matrix helps determine the order for dealing with different issues or selecting solutions according to their relative importance. In this topic, you will create a prioritization matrix to identify crucial issues […]

An interrelationship digraph, also called a relations diagram or network diagram, is a tool that depicts relationships among different elements, areas, or processes through a network of boxes and arrows. It is usually used by Six Sigma teams to understand cause-and-effect relationships among different factors of a problem.

The metrics of a Six Sigma project reflect customer needs and ensure that the internal metrics of the organization are achieved. The selection of project metrics is one of the crucial elements in the Define phase of the Six Sigma methodology. Six Sigma project metrics can be categorized into primary metrics and secondary metrics. Primary […]
