Q

What chart types are supported? Xbar / Range, etc.

A

Our software is a no frills software application. We support X Bar and R Bar charts. There are also special Line Control Charts for Cp and Cpk, (process capability). We have a very unique Distribution/Histogram chart.

Our software was designed not with the Fortune 1000 company in mind that has unlimited resources to hire a lot of very educated people, although it can also be used by them, but with small business/suppliers that MUST meet Six Sigma, ISO, TQM, and/or other Quality Assurance Systems requirements consultants. Our program was designed by Jim Winings with guidance from the founding fathers of Six Sigma.

Our Distribution chart is simple. It plots and draws a bell shaped curve over the actual data, and then another bell shaped curve around the specifications. This allows one to see how far the actual data is from the specifications at a glance. It also has indicators that show where the end users selected design margins are in relations to both the actual data and the specifications.

Refer to the features page.

Q

How is chart annotation supported, if at all?

A

At the current time our software does not support annotations. Support for annotations will depend on our market requirements. In order to provide Total Customer Satisfaction, we will incorporate it if demand for such is high enough to justify the cost.

Q

What data interfaces are supported, both input and output, i.e., how do we get data sets into and out of the SPC package. Is there a standard interface to relational databases, to Excel, etc.

A

We do programming and consulting to tie manufacturing systems into our software package for our customers.

We added an import function that will work with .csv comma delimited files and an export function to export as a Microsoft Access database file. The export actually just copies the database file with the correct file extension, (mdb), for Access.

However, you can copy the charts, etc. via the {Edit-Copy Special} pull-down menu. This will allow you to save the chart to disk and use another software package to print the charts or copy the chart into the clipboard and paste it into a program like Microsoft like Word or Excel. You can also export the data sheet as a .csv comma delimited file.

All the line charts will copy as meta files or BMP, (bitmap). You can edit the meta charts in Word. The histogram will copy as a BMP, bitmap file. You can copy and paste the data from the data list, NOT the tab card, into Excel, etc.

Because it uses a Microsoft Access database, you can of course load it into Excel and Access, and other packages that support Access or comma delimited files.

If you use Access or Excel, etc. with this program, me sure to make a copy of the database, or use the export function, before opening it. Not doing so may put a NEWER JET database object into the database and this software will no longer be able to open the database. We use an older version of the database engine for backwards compatibility reasons.

You should be able to use other software to get the data from the database. However in the past, using a newer version of Access could make it so that this software would no longer open it's database. Therefore it is strongly recommended that if you want to use Access to get to the data, make a copy of the database file, or use the export function, and open the copy with Access. Not doing so will with out a doubt, corrupt the database.

Q

Are capability studies supported?

A

There is NOT a Capability Study button. This software was design to be ran at a production line or an incoming inspection department. But it could be used for such studies.

Q

What are the cost, licensing, and support arrangements?

A

See the 'Price' page for cost. If none of these work for you, contact us and we will find one that does. Support is handled by me. You don't get a tech support person or a sales person. At this time, you get to talk to the person that wrote the software and has had the 'Six Sigma' Training and also has used it in real time. We feel this is better than other software's support options. There is also a Support Forum where customers can post or answer questions and and even stay anonymous if desired.

Q

How does the package support notification, if at all? Popup dialog box, email, etc.?

A

At the current time, anyone that purchases the software and supplies their correct e-mail address will be notified by e-mail when the next version is ready for him or her to download. The customer is then directed to the customer download area where they enter their user name and password.

We only update the .exe file so the updated version are less than 500k, zipped, to download. If the customer requires the full install again, about 6 megabytes, then we provide it at no additional charge.

Q

How well does the package scale? Are there likely to be problems as the number of parameters tracked or the number of data points increases?

A

This depends on Microsoft. Our software uses the 'JET' database engine and we are going to provide ODBC connectivity sometime in the future. This means that it will depend on the OEM. However, you can create many different databases, so you could just limit the number of data points per database if there is a problem. We have had NO reports of such problems and testing with several hundred samples of 5 observations, (using Stratified sampling), shows absolutely no performance break down.

Q

Can you add Pre-Control limits?

A

Yes you can add 'Pre-Control' limits to the X-Bar and Range charts.

TOP


Q

Do you need Access or Excel to use ZeroRejects?

A

No. ZeroRejects is a stand-alone program. It does not require any other software programs to operate.

TOP


Q

Can you enter only one sample? This is due to the fact that traditional X bar and R Bar charts must use a stratified sampling plan.

A

No.
