Six Sigma - SPC Software Comparison

In the Market for Six Sigma - SPC Software? Here are Some Things to Consider:

  1. Do you want a separate, stand-alone software application or something that works right in Microsoft Excel with your data?
  2. What is the statistical expertise of your users and do you have days or just hours to train them?
  3. Do your users have other job responsibilities besides creating charts and other improvement documentation?
  4. How much money do you have in your budget?
  5. How picky is your audience about how your charts look?

I trialed eight different spc software and spc for excel addins within the same price range and nothing even comes remotely close to the QI Macros. There was no comparison.

Stand Alone Application or Microsoft Excel Add-in?

This factor is the single biggest decision to make as it influences all other factors.


Stand-Alone Software Application

Microsoft Excel Add-in

SQC Pack®, Minitab®, JMP®
QI Macros®, Sigma XL®, SPC XL
Installation Installed as a separate application on a PC or on a network with login requirements Adds a new tab on Excel's Menu Bar

Perpetual (one time purchase) or subscription based (monthly or annual fee).

Usually a perpetual single user license.


Higher because the application was built from scratch.

Minitab® Annual License: $1,851/year

SQC Pack®: $1,290 for a single user license.

Lower because add-ins use the power and functionality already available in Excel.

Around $300 for a single user perpetual license.

QI Macros price is $369 USD per license.

Even if you already own a more expensive standalone package, a tool like Minitab, QI Macros can make life easy when dealing with Excel data.

Ease of Use

More difficult as users need to learn a separate application.

Easier as most users are already familiar with Excel.

Data Input Data must be imported into the application from Excel or another system. Most of your data is already in Excel. If not, most systems already contain functionality to export data into Excel.
Charts and Other Output

May or may not be able to be customized and / or shared with unlicensed users.

Excel charts are easily customized, easily copied to Word and Powerpoint and easily shared with unlicensed users.
Typical User Statistician or someone whose job is primarily dedicated to statistical or data analysis. Business person who needs to analyze data and create charts in service to their primary job functions.

I love having the QI Macros on my PC. It is sooo easy to use with Excel. I enjoy not having to use a separate program just to chart QC projects. And the options…oh my! Thank you so much for making my life easier, AND at a very reasonable price!!!

Other Six Sigma Add-ins for Excel

QI Macros

Ease of Use
User Interface

Designed to work like Minitab which was built to teach college students statistics. Users often report this makes the software difficult to learn and use. Built from scratch with business users in mind. Can be learned in an hour with our online tutorials.
Create a Chart

1. Use a decision tree to choose the chart. You have to know which chart you want.

2. Identify your data range to the software.

3. Set various criteria.

4. Run the chart.

1. QI Macros is the ONLY software that asks you to select your data first which makes it possible to automate chart and stat selection.. This makes you look like an expert.

2. Let one of the QI Macros chart wizards select the right chart for you. Or select the specific chart you want.

3. Analyze the resulting chart

Data Mining

Use Excel PivotTables or Crosstab to analyze rows of data. QI Macros is the ONLY software with an Improvement Project Wizard that can create entire improvement projects from rows of data with a single click. It creates PivotTables, control charts, Pareto charts and Fishbone diagrams automatically.


Use Excel Drawing tools or Visio.

QI Macros has over 100 fill-in-the-blank templates for Lean Six Sigma, many of which automate the creation of diagrams such as the Ishikawa/Fishbone Diagram and Value Stream Mapping.

Formulas and Flexibility

Provide just the numerical results. If you want to adjust an input such as significance or spec limits, you have to rerun the chart or stat.

QI Macros lets you see all of the formulas. If you change the signficance in a t test, the calculations update automatically saving you the time needed to rerun the stat.

QI Macros also interprets p-values and other results for you. No guesswork.
