Cause-Effect Matrix

Matrix of Design Elememts (factors) over Functional Requirements (responses). Use for knowledge management, DOE planning.

1
Effects
This is the list of effects. In this example effects are the CTQs (critical to quality) from QFD but it can be any other list of items. Those items should be measurable and should have a unit.
2
Importance
Importance table of the effects. Values here may come from common prioritization methods, e.g. AHP or from a QFD matrix.
3
Specifications
This is the table of specifications for effect items - primarily the unit of the elements.
4
Causes
This is the list of causes. Here: a generic list of parameters. It can also be linked to the list of design parameters or the process parameters.
5
Importance
Importance table of causes. Values are calculated by linear mapping from the effect importances and the central matrix.
6
Details
This table contains more information about the causes.
7
Levels
This list contains the different settings for DOE planning and evaluation.
8
Cause-Effect Matrix
This is the central matrix of the worksheet. Set a relation wherever a cause (column) has an influence to an effect (row).
9
Selector
The central matrix can store different analyses with different relation values. For example you can start by documenting initial knowledge, and later the results of an experiment. This selector allows you to switch between the different sets of data.
