Economic Analysis:  This method not only provides for cost analysis but also adds the element of opportunity cost.  Traditional cost analysis misses the obvious cost of the next best opportunity for a given resource.  Economic analysis adds a full picture to any cost analysis while still delivering the necessary base cost analysis.

Total Quality Management:  TQM is the often quoted but rarely understood methodology for continual process improvements and quality control methods.  Invented by Dr. W Edward Deming, TQM provides the methods and systems to provide an ever evolving system of cost and process improvements.  TQM not only provides for a complete analysis of costs and processes but also looks at the culture surrounding an issue.

Six Sigma:  This quality and costs process has quickly become the standard for the modern corporation.  Although originally developed for manufacturing many organizations have adapted this process to service organizations.  Although called many things, Six Sigma strictly speaking is one mistake per one million opportunities.  This process is statistic intensive and produces quite extensive results with the costing and statistical process information to prove it.
