Hello there !
My job is to find a good and useful software for statiscal analyses in our six sigma projects.
Is there any help?
Greetings,
Ralf

There are really two packages predominately used in the SS community. Minitab and JMP. You need to define good. As far as the calculations the formulas do not differ. I have n’t seen someone come up with a breakthrough formula for the mean median or mode, etc. The question is ease of use, support, etc. You will probably get lots of feed back about the really cool speacial analysis features and tools. Bottom line is they don’t get used much. If you have someone who need some high level analysis technique then buy them some thing and send them back to their office. BB will be able to do 99.9…..% of what they need to do with either package.
I have never done a deployment with JMP. Motorola uses both. Allied, GE, & Ford use Minitab. I prefer to use it because of the support and commitment Minitab has made to the SS community. We have had strong onsite support from the Minitab staff since wave 1 at Allied. They have reacted to our input and incorporated changes to help BB’s.
You might want to see what your customer is using. There is nothing more nonvalue added than watching two BB meet to work on a project and spend a few hours verifying how each others software works.
For my money – Minitab is the software of choice.0March 9, 2002 at 8:53 pm #73041

Many applications have good basic statistical tools. A subset of them have good DOE tools. MINITAB, JMP, Statistica, and StatGraphics tend to be the only ones with complete measurement system analysis and process capability tools.
All four are proficient. Try going to their websites and downloading thier demos. The only way to gain an opinion is to take a test drive. Unfortunately many of these demos are crippled by manufacturer – JMP forces you to use included data – Statistica only provide one of the many modules. MINITAB & StatGraphis do better by providing a complete installation, but it will timeout and stop functioning after a month or so. If necessary, call the manufacturer and try to arrange to use a full installation for testing.
JMP – http://www.jmpdiscovery.com/MINITAB – http://www.minitab.com/Statistica – http://www.statsoft.com/StatGraphics – http://www.statgraphics.com/
Another thing to consider is the license arrangement.
Minitab Inc., provides a license which allows concurrent use on a LAN. That means that you can purchase a few licenses, load it onto a LAN, and provide access to maybe hundreds of potential users.
SAS Institute, makers of JMP, do not offer concurrent licensing. It used to, but stopped back in the midtolate 1990’s.
For myself, I use MINITAB.0March 10, 2002 at 2:40 am #73046If your organisation is already using a package then I suggest you just go with that because people will be familiar with it and will use it more freely.
We use Minitab and I find it very good. I haven’t used any other software so cannot comment on others. Also, we have a corporate license for Minitab so any employee can have Minitab installed on their PCs.
Reduction in variability is the essence of 6Sigma so whatever you choose, ensure that it is consistent across the organisation because having different software packages across different departments will is just another source of variability.
TJ0March 11, 2002 at 1:12 pm #73066I think Minitab serves the vast majority. JUMP is for the statistical elitists, it also is very good,however, not as user friendly as Minitab.

be notified via email.Here at Sony, we primarily use SPC XL. If you are any good with statistical formulas, you would be amazed at the functions that are built into Microsoft XL. SPC XL is basically a bunch of macros that run with your Microsoft Excel. These macros take input in spreadsheed tables and convert them into pretty charts, etc. I believe we use it because it is very economical, but it will do the following large list of charts, analysis tools, and quality tools:
Control Charts: XbarR, XbarS, Indiv. Moving Range, p chart, np chart, c chart, u chart.
Analysis Diagrams: Histogram, Cpk, Scatter Plots, Pareto Diagrams, Summary Stats (Dot Plot), and Box Plot
Analysis Tools: Multiple Regression, Correlation Matrix, t Test Matrix, F Test Matrix, Independence Test Matrix, Test of Proportions, 1 Way ANOVA
Confidence Intervals: Normal, Std. Deviation, Cp and Cpk, Binomial, Poisson, and Exact Small p…
Sample Size: Normal or Binomial
Quality Tools: Run Chart, Cusum Chart, Product Capability, FMEA, and X bar +/ 3s Chart.
Some of the other programs might be able to do a little more, or produce charts that look a little fancier, but for the money, this is a good choice and an alternative to the other two.0March 11, 2002 at 2:53 pm #73088

JUMP, MINITAB, STATISTIC, SPC XL (never make across)
Up to Mid 97 SAS – we used, but discontinued !! on price issues.
Our company used MINITAB for SS and it is also popular choice. It is used across the SS community Champ, MBB, BB and GB. In our company – other software are ultised, but mainly by statistician. Though, who have used Minitab for few year, have seen progress update and change, this shows the Minitab as a company is learn to users. I find Minitab is user friendly.

0March 11, 2002 at 6:08 pm #73093The company I work for uses MiniTab.
MiniTab has many advantages over other statistical software. First, it comes complete. You don’t have to buy any extra modules for DOE or multiple regression analysis. MiniTab’s technical support is also very good and very prompt.
I’ve seen a couple of other stat. programs: SPC/PI+, SPCC and SQC. MiniTab is my preference.

What did you think of SPC/PI+? I know it’s somewhat dated but does do SPC very well.
