O.K., what's the catch? Most of these programs are complementary products
that go with books that Ganesha is promoting. You don't need the books
to make them work, but they make the books more useful. For example, if
you are teaching statistical process control, you can use the SPC software
with Levinson and Tumbelty, SPC Essentials and Productivity Improvement:
A Manufacturing Approach.
Important: before selecting a program, you must configure your browser
to (1) launch a helper application (like Microsoft Excel or Corel Quattro
Pro) or (2) save the file to disk.

No freeware offered here constitutes engineering advice or an engineering

To the best of my knowledge, the ActiveX documents are safe to run on your
computer. They are not designed to access the hard drive (unless you instruct
them to save a report to a file, in which case that's all they will do).
I have tested them on mine.
ActiveX programs require Microsoft
Internet Explorer 4.0 (Service Pack 2 or higher)
or version 5 to operate.(download for free from Microsoft). They are ActiveX
or Internet Explorer. I have not yet been able to get these programs
to work with Internet Explorer 3.0, but I have run them on two different
computers with IE 4.0. Comments are welcome. Send Mail email@example.com
ActiveX Troubleshooting note: Microsoft
Developer Network Library, April 1999
A dialog box with the following messages appear in Internet Explorer:
Opening file <ActiveX Document>.VBD
What would you like to do with this file?
Open it or Save it to disk.
This error occurs because the Visual Basic 5.0 Run-time Library (MSVBVM50.DLL)
is not installed. This will most likely occur if the Internet Explorer
safety level is set to High. Set the Internet Explorer safety level to
Medium or None.
I have deliberately saved the spreadsheets as older Excel (or Quattro
Pro) formats, to make them readable by newer versions of Excel, Quattro
Pro, and Lotus software.

Animated Process Simulator
Acceptance Sampling Plan Designer
Gage Capability (reproducibility
and repeatability) (ActiveX)
Empirical control charts
Multiple Attribute Control
Charts (binomial, Excel 4.0)
u (defect density) Chart
(variable sample sizes, Excel 4.0)
Inventory shelf life (Excel
Normal probability plot
Empirical control charts, with variable sample size capability.
Multiple attribute control charts are check sheets or tally sheets
with control limits. They are:
more powerful than traditional attribute charts (np, p, c, and u)
capable of tracking several defect or nonconformance sources simultaneously
easy to use on the factory floor
Traditional u (defect density) chart, capable of accepting variable sample
Supports ISO 9000 by keeping track of material or inventory that has a
If you have MathCAD 4.0 or higher, use this to do normal probability plots.
Generate random numbers from the normal, binomial, or Poisson distribution
to create SPC examples for classroom instruction. Customize the examples
for your class' requirements.
Uses ActiveX, you need Internet Explorer to run it. (Netscape Communicator
is supposed to run ActiveX programs, but I haven't found a way to make
it work.) Download IE 4.0 for
free from Microsoft.
Animated simulation of the targets in Chapter 3 of the book. Simulates
300 shots from a capable, in-control process side by side with 300 from
an out of control process of the user's choice. Also simulates the overadjustment
example (funnel experiment.)
Designs acceptance sampling plans (inspect n items, accept on c or fewer
defectives) to meet specified quality levels and risks:
Gage reproducibility and repeatability calculations.
Acceptable quality level (AQL), producer's risk alpha
Rejectable quality level (or lot tolerance percent defective), consumer's
Also plots operating characteristic curves
