Six Sigma Tools for Quality and Process Improvement

This package contains functions and utilities to perform Statistical Analyses in the Six Sigma way.
Through the DMAIC cycle (Define, Measure, Analyze, Improve, Control), you can manage several Quality Management
studies: Gage R&R, Capability Analysis, Control Charts, Loss Function Analysis, etc. Data frames used in
"Six Sigma with R" (Springer, 2012) are also included in the package.
Use the package to perform Six Sigma Methodology tasks, throughout its
breakthrough strategy: Define, Measure, Analyze, Improve, Control (DMAIC)

Define: Process Map (ss.pMap), Cause and effect Diagram
(ss.ceDiag);

Measure: Gage R&R study (ss.rr); Capability Analysis (ss.study.ca);
Loss Function Analysis (ss.lfa)

Analyze: Confidence Intervals (ss.ci)

Control: Moving Average Control Chart

Soon: further functions

The current version includes Loss Function Analysis, Gage R&R Study, confidence intervals, Process Map and Cause-and-Effect diagram. We plan to regularly upload updated versions, with new functions and improving those previously deployed. The subsequent versions will cover tools for the whole cycle:

Define

Measure

Analyze

Improve

Control
