Data Analysis
Data analysis is used in the 9-step Integrated Enterprise Excellence (IEE) business management system when evaluating an organization as a whole to determine what areas of the business should be further investigated for improvement opportunities (step 4). Data analysis is also used in step 7 of the IEE system when investigating what might be done differently to improvement a particular process’ output response.
Data analysis that attempts to uncovering causal relations to a response can involve hypothesis tests that are to assess what is impacting an IEE 30,000-foot-level process-output predictive response. Statistical tools such as linear regression and analysis of variance can be involved in this assessment of historical data. Design of Experiments (DOE) can also be used to statistically determine through experimentation what factors and levels of factors might improve a desired response.
