### What is Process Stability?

Process Stability Process A process is a set of sequential activities that convert the input to the desired output. Stability Process stability is the ability of the process to perform within a predictable limit. We can also state stability of a process refers to its predictability. Why processes become unstable? Processes tend to become unstable over time due to variations. The variations occur either because of the inherent nature of the process or some external or forced changes, called disturbances....

### Systematic Problem-Solving

What is Problem-solving? Before we understand problem-solving, let us first calibrate ourselves on 'what is called a problem?' A Problem When there is a gap between our expectations and reality, we feel unhappy – which is a Problem. This is how a deviation from the specification, a failure to meet timelines, etc., become our problems. A problem could be defined as “the gap between our expectations and actual state or observation”. From the gap analogy, we also understand that as...

### Statistical Tools & Application Matrix

What are statistical tools? Statistics is a branch of science that deals with samples, measurements, calculations and estimation of population properties. Statistical Process Control Statistics found its application in manufacturing way back in the 1920s with Dr Shewhart of Bell Laboratories. We acclaim him for his application of Statistics in Manufacturing Science to predict when the process will produce a defect. From there on, the application of statistics in manufacturing spread across the world and became instrumental in the Japanese...

### Statistical Process Control using Minitab

What is Statistical Process Control? SPC, or statistical process control, is a framework embedded with the statistical tools used to monitor, control, and improve processes.  Conceptually, it applies the statistical technique to control the processes to improve their reliability and predictability. What is data? Data is a collection of facts, such as numbers, words, measurements, observations or even just descriptions of things. Any and every piece and form of information. What is Data Analysis? The collection of structured data –...

### Data Analysis using JMP

What is JMP? JMP, usually pronounced as 'jump', is a statistical data analysis tool that works well on MAC and Windows OS. It is developed in 1989 by the SAS institute. Because of its user-friendly nature, people in Six Sigma, Design of Experiments, Statistical Process Control (SPC), research and development extensively use JMP. JMP software focuses on exploratory data analysis and visualisation. It provides lots of features to easily and seamlessly switch between various visualisation tools on a single screen....

### What is ‘Quick Wins’ in Six Sigma?

Quick Wins are the actions/projects that require minimum efforts and would offer a reasonable benefit in a Six Sigma Project. Six Sigma Framework Six sigma is an investigative problem-solving methodology. It provides a proven framework and sets of tools and techniques to help us solve problems.We call this framework the DMAIC method, depicting five steps of problem-solving. They are Define, Measure, Analyse, Improve and Control. Six sigma also prescribes tools and techniques for application in each phase.It also helps us...
