Quality Control & Improvement Edition Improve your products and services with statistical process control (SPC).

Ideal for anyone involved in manufacturing products, managing processes, implementing a six sigma or other quality improvment programme.

Meet your customers’ expectations and keep them satisfied with powerful statistical analysis to understand processes, bring them under control, and find improvements that better your product.

  • We have incorporated Analyse-it into our real-time daily QA analysis, making us both more efficient and proactive in addressing QA issues. Analyse-it has saved us time and provides the statistics and professional reports we need.

Bring processes under statistical control

Gain insight and improve process performance with Shewhart variable and attribute, CUSUM, and moving average control charts (EWMA & UWMA). Apply WECO, Nelson and Montgomery rules to help identify possible out of control situations. Use stratification to gain further insight into problems and spot trends and patterns. And when you've implemented improvements, or made other changes, phases let you track performance before and after so you can ensure improvements have been made and are sustained.

Ensure products are meeting end-user specifications

Determine process capability indices for process performance to ensure you deliver products that meet your customers’ requirements. A happy customer means fewer rejected goods and service complaints, improving your business and lowering costs.

Identify improvements that will reap the most rewards

Pareto analysis helps you quickly identify commonly occurring defects so you can focus your efforts making improvements that will reap the most rewards. Stratification lets you break-down defects so you can identify contributing factors, such as an operator that is influencing defect rates, or look at defects before and after process improvements to ensure the changes are reducing defects.

Plus it includes the
Analyse-it Standard Edition...

All the features from the Analyse-it Standard Edition are included so you can improve processes and products by identifying solutions using hypothesis tests and model fitting techniques.

Integrated into Microsoft Excel, so it's easy to use...

That's right. Analyse-it integrates into Microsoft Excel 2007, 2010, 2013, and 2016 for Microsoft Windows. There's virtually no learning curve, and the intuitive user interface and logical task-based workflow makes sense to those of us that aren’t programmers or full-time statisticians.

All your data and results are kept in Excel workbooks, making it easy to collaborate and share them with colleagues, and meaning there's no locked-in file format.

Software you can trust

We've developed statistical software for more than 25 years, have a reputation for high-quality software, and have worked worked with some large companies on the back of that solid reputation.

But it's our customers that matter - the researchers, manufacturers, and laboratories, including many of the world's top companies and universities. Check out the latest reviews on Capterra, in the meantime here are a few of our customers...

Accurate and reliable

You might have heard Microsoft Excel isn't up to the job of statistical analysis. It isn't. The built-in functions just aren't built for accuracy. So we don't use a single one. Instead, Analyse-it handles all of the calculations internally, using reliable algorithms and IEEE 754 double floating point precision. And the results to prove it? See Analyse-it's performance against the NIST-StRD.

Validated, tested at every stage

We've conducted thousands of tests to put Analyse-it through its paces. They cover all releases and service packs of Microsoft Excel 2007, 2010, 2013 and 2016. What's more, validation tests are run automatically after every change to the software so you can be confident the statistics are correct. And stay correct. See our development & validation process.

Dependable support

No need to resort to old textbooks. Analyse-it includes detailed help that’s written in plain English. And if you get stuck we’re here for extra help - aiming to answer your queries within 24 hours.
