Claim 3:
4. A method for production analysis comprising:
receiving production data at a processor from a plurality of tools spatially arranged within a manufacturing facility;
creating a hierarchal topology of the data in a memory coupled in communication with the processor, wherein each level of the hierarchal topology is based on a different one of a plurality of static parameters that are selected from a list consisting of: a tool identifier, a batch identifier, and a spatial orientation;
displaying, at a user interface implemented by the processor, a first analysis of a first level of the hierarchal topology, wherein the analysis contains parameters related to other levels of the hierarchal topology;
receiving, via the user interface, a selection by a user of a first parameter displayed in the first analysis, wherein the first parameter is a lot i.d.;
in response to the selection of the first parameter displayed in the first analysis, generating and displaying at least one intermediate analysis and receiving at least one selection on the at least one intermediate analysis;
in response to the at least one selection in the at least one intermediate analysis, generating a second analysis of a second level of the hierarchal topology, wherein the second level is related to the first parameter;
further in response to the at least one selection in the at least one intermediate analysis, updating the user interface to display the second analysis of the second level of the hierarchal topology;
in response to a user selection of a first filter in the display of the second analysis, displaying a third analysis that represents only data values of a subset of the data values in the second analysis; and
in response to a user selection of a second parameter value in the third analysis, displaying a fourth analysis that represents data values that match the second parameter value and also match the first filter, wherein all of the data values of the fourth analysis pertain to the first parameter and include variable names that are ranked according to a metric selected from a list consisting of: out-of-sigma count and p-value.
