Working with Target Teams Inc.

by Sergiy Nesterko on June 6th, 2010

Starting in the fall of 2009, I have been fortunate to be engaged in several projects with Target Teams Inc., a company offering psychometric testing services based in Cambridge, MA. The idea is to uncover the personality of, say, a prospective employee via a series of questions and subsequent statistical analysis of the responses.

One of the offered tests is DISC. DISC stands for Dominance, Influence, Steadiness and Compliance. The test has been designed with the purpose to reveal the extent to which the latter behaviour styles are expressed in a respondent. It consists of 26 frames of four items to be rank ordered by respondents. Based on the responses, two scores are then calculated for each behaviour style. They are called the scores for Actual and Modified behaviour styles. The goal of Actual score is to represent inherent, less public and perhaps somewhat hidden from self behaviour style. The goal of Modified score is to account for behaviour style as expressed in a setting and/or as perceived be the responding individual.

I cannot go into detail as to what exactly I do for Target Teams. Generally, my role is to help improve the products from the statistical perspective. It has happened so that as part of the job I make nice pictures as the one shown in Figure 1.

Greta has been a wonderful person to work with. I have learnt a lot not only about psychometric tests, but probably more importantly also how to apply my statistical skills to this field and actually help Target Teams improve and achieve goals. I will do my best to keep up the work as I am certain that this collaboration helps both the company and me grow and reach new heights.
