preparing the available data, about each high-value entity, for analysis by:
validating values for the available data,
converting non-numeric values that make up the available data into numeric values, and
inverting scales as needed such that increases in each independent variable lead to increases in a correlating dependent variable;

scoring each high-value entity variable by multiplying each independent variable, of said each high-value entity, by the computed weight to create a score for every high-value entity;
classifying all high-value entities as cases that have a similar calibration score that is based on a) multiplying each independent variable by its computed weigh to create a weight product, b) summing the weight products for all independent variables into a score for each dependent variable, and c) calculating a combination of scores for each dependent variable to classify similar cases of high-value entities;
categorizing each high-value entity according to the calculated combination of scores for each dependent variable assigned to the entity; and
representing all high-value entities as high-value entity representations in a calibrated visual model, wherein a newly classified high-value entity, which has missing data in its independent variables, is displayed in a graphical manner such that similarly scored high-value entities are represented in close proximity to one another.

establishing a guard band between zones in the calibrated visual model, wherein high-value entities whose high-value entity representations fall in the guard band are considered to be only tentatively classified, and wherein the initial position of a high-value entity representation relative to a guard band is incorporated into the step of computing weighting factors computation of weights such that high-value entity representations are moved out of the guard band in order to improve zone classification of the high-value entities.
3. The system of claim 1, wherein the high-value entities are selected from a group consisting of ultra-large-scale projects, unique projects, customer segments, product brands, market geographies, service types, legislation and regulations.
