ITK has integrated the 6 sigma approach in SPC Wizard and it is also implemented in DataLyzer.
The calculation of the sigma value for a process is not always very clear and easy. To facilitate the calculation of the sigma value of a process ITK has developed the sigma calculator. This freeware program can be downloaded below and you are encouraged to distribute it as much as possible.
SPC Wizard has the following features which will facilitate the application of 6 sigma:
SPC Wizard is the ultimate tool to use in six sigma environments. SPC Wizard has several strong advantages over other statistical programs often used in six sigma programs. All analysis is interactive which means you can evaluate what-if hypothesis directly on screen and show relations btween graphs. With 2 clicks of the mouse the quality tools can be applied: Control chart, histogram, scattergram, Pareto, multi vari analysis and frequency distribution. Wizard has a direct link to ACCESS and Excel and is very easy to use even for green belts. SPC Wizard fills the gap between Excel and sophisticated statistical programs. An sound ICT strategy for quality improvement is sophisticated packages for black belts and master black belts and SPC Wizard for all other users.
Free F and t test calculator
To stimulate the use of the F and t test we have provided a free F and t test calculator. You can enter the average, sigma and number of measurements of 2 datasets and the calculator will give you the full F and t test analysis with a summary what the result is. At that point you can analyse the influence of the chosen confidence percentage. See graph belowITK has extensive experience in training black belts. If you want more information please contact ITK.
