WHAT YOU GET

Competing software** reference Dr Wheeler


...but get it wrong.


With Maxi-Q you can be sure you get it right.


Dr Wheeler, the world's most respected and referenced process statistician, is a co-founder of Maxi-Q. He has written extensively about the failure of software to correctly implement process improvement statistics. Legacy software like** Minitab, JMP, Statgraphics, BPI, QImacros, Engine Room, SigmaXL all reference Dr Wheeler's brilliant work but fail to understand the theory. Their errors range from the "goofy" 1.5 sigma shift and nonsensical Six Sigma Tables, to a failure to understand rational subgrouping and the roles of normality and homogeneity.

Maxi-Q has many unique and innovative features to guide and assist users. The Process Mapper has automatic line drawing and optimal routing along with logic checking; histograms include a special tool to extract maximum process information. Maxi-Q is a comprehensive product including a broad suite of both statistical and non statistical process improvement tools.



50+ Improvement Tools

Process MapperFlowcharts that route themselves. Basic and extended ISO symbols. A logic checker that helps ensure that you work accurately.
Value Stream MapperStandard symbols, lead time, Takt and value added plus information flows. Graphical displays to highlight bottlenecks.
IdeasRigorous problem definition addresses many problems. Brainstorm possible causes and drag to Affinity groups.  Automatically generate an editable Cause and Effect Diagram.
Control chartsXmR, X-bar R, p, np, c, u, CuSum and EWMA. You can use either Box Cox normalization and/or Western Electrics rules, or select the correct approach.
Capability 8 PackCp, Cpk, Pp and Ppk are not constants.  They are statistics that vary over time.  Control charts are essential to determine stability for capability to mean anything.
Statisticst, z, F tests, Chi-square, ANOVA, ANOM, Gauge R&R, MSA, Mann Whitney, Kruskal-Wallis, 8 types of Design of Experiments, Multivariate etc; and their requirements.
Ramirez-Runger TestControl chart fall back. A homogeneity test; the test before all others. Unlike all other tests-of-fit, it takes the time-order sequence of the data into account.
GuidanceThe aim of MaxiQ is not to dump 50+ tools on you, but to guide you with simple instructions, in the correct path to process improvement.

Why leaders are abandoning overpriced legacy suites.

A double or triple tick is where Maxi-Q does more than tick the box.
