Statistical Analysis
- Descriptive Statistics
- Used to describe the main features of a collection of data in
quantitative terms. (Central Tendency, Dispersion [i.e. spread or variation] )
- Design of Experiments (DOE)
- Used to design a structured experiment for follow-up analysis
- Correlation
- Used to determine the linear relationship between two continuous variables
- Regression
- Used to determine the relationship between an output variable, and 1 or more input variables
- Hypothesis Testing
- Used to determine which of two opposing hypothesis (or assumptions) appears to be true
- Measurement System Analysis (MSA - - AKA Gage R&R)
- Used to quantify how much of observed variation is due to gage variation and operator to operator
variation
- Graphical Analysis
- Used to graphically summarize your data
- Capability Analysis
- Used to determine the capability of an in-control process. Process must be in control to get valid results
from capability analysis
- Control Charting
- Used to determine whether or not your process is in-control
- Analysis of Variance
- Used to determine if the means (averages) of several populations are equal
- Design Optimization (Robust Design)
- Used to determine optimal settings of one or more input factors to minimize sensitivity to
variation of the output response
Six Sigma Analysis
- Design Failure Modes and Effects Analysis (DFMEA)
- Used to document the potential ways that a design may fail so as to reduce the risk of failure
through mitigating actions
- Process Failure Modes and Effects Analysis (PFMEA)
- Used to document the potential ways that a process may fail
so as to reduce the risk of failure through mitigating actions
- Risk Assessment
- Used to document the risk of failure of a project
- Morphological Matrix (Concept Generation)
- Used to generate all possible solutions based a defined set of multidimensional functional
requirements
- Pugh Matrix (Concept Evaluation/Selection)
- Used to rank a set of design solutions according to how well they meet a defined set of functional
requirements or critical to satisfaction metrics
- Quality Function Deployment (QFD -- House of Quality)
- Used to prioritize design elements and assure alignment with customer needs
- Theory of Inventive Problem Solving (TRIZ)
- Used to systematically solve design contradictions
Any and all design/analysis work performed for my clients will be held in strict confidence.
