ABSTRACT
The Six Sigma methodology recognizes that there are many sources for inputs, outputs, and feedback for an organization. All inputs and outputs of a process should be measurable so that quality can be controlled. Quality improvement projects cannot happen without the appropriate decision makers taking ownership of the project. Every organization wishing to embark on a Six Sigma journey must settle on a few key performance indicators (KPIs) to use for planning and guidance, as well as use other metrics called key support indicators in the role of supporting the KPI. Hard cash is cash that allows companies to do the same amount of business with fewer employees (cost savings) or handle more business without adding people (cost avoidance). A cost–benefit analysis may also be initiated after a project has been completed to determine whether the project should have been undertaken in the first place.
