I have been using SPC for Excel for over a decade, it was $60 when I first purchased it and fairly new to the market however it has come a long way since then and so has the cost ($329). Unfortunately I haven't run any MSA studies in it however the do have lots of free support on how to use the software including video tutorials on their website.
I use their capability analysis quite a lot as the graphical and data output is aesthetically pleasing and includes all the data I need (see example)
Please note that I have no association with SPC for Excel, I used minitab for 10 years when I worked for General Electric but could not afford a copy when I moved jobs so looked for something that had the tools I needed to supply data and analysis to my customers, and found SPC for Excel.
Miner, you are our statistics expert, and SPC for Excel do give you a free 30 day demo of the full software to play with, I would be very grateful (as would a few other people that frequent this forum) if you could have a look and give us your honest opinion on SPC for Excel.
Once again I have absolutely no affiliation with SPC for excel, just been using it for years and would like to know from an expert if it is any good.
