Chart 7: Comparing MBTI of CM Process
Roles vs. CM Tools Roles

The results were very interesting.  I had hypothesized that the CM tool roles would include a higher percentage of INTJ (introverts really focused on completing their work).  However as the chart indicated, it was the CM Process roles that tallied 46% of the MBTI® as INTJs.  That is almost half of the sample size!  This is amazing.  The next highest was ESFJ at 15%, then much smaller percentages followed (no higher than 5%).   

For the CM Tool role, the INTJ type also had the highest percentage of folks (25%) within this sample.  However, this was a more diverse group that included a fair amount of folks in other types.  This includes 14% in ENTJ, 14% in ESFJ, 10% for ISTJ, 7% for INFJ, and
7% for INTP. 

Comparing CM Professionals by Temperament to the General Population
More telling than the comparison of the population groups (overall vs. CM professionals) by Myer Briggs types is the comparison of population by temperament (grouping of related types).  Therefore, this measure compares how CM professionals are spread across the 4 temperaments (as a percentage) in relation to the overall population.

Chart 8: Temperament and CM
Professional Sample Population vs. Overall Population

What can be noticed from this chart is that there are a significant number of CM professionals expressing the NT or Rational (and Mastermind) temperament (53% of CM professionals vs. 8% of the overall population).  Why might this be?  In examining the traits of NT, the Rational tends to value competence and intelligence, they strive to learn, grow and predict.  They like to control their environment and have a tendency towards technology.  Considering these traits and the traits needed to make a CM professional successful, it may be understandable why there are so many Rationals within the CM field.  

Inversely, very few CM professionals express the SP or Artisan (and Freelance) temperament in comparison to the overall population (7% of CM professionals vs. 40% overall).  In examining the traits of SP, the Artisan values freedom and spontaneity. They do not like constraints, are more impulsive, playful, and creative, and have a tendency toward the arts.  Considering these traits and the traits favored to make a CM professional successful, it may be understandable why there are so few Artisans within the CM field.  However, do note that 7% in 2007 is up from 3% in 2003. 

Note: the percentages of temperaments across the population vary from reference source to reference source.  The percentages listed here are representative averages across the reference sources.     

CM Professionals by Preferences
The next measure focuses on the individual preferences of the responses and examines if there is a leaning toward specific preferences.  The outcome is quite interesting in that it results in a strong propensity toward certain preferences.

9: Percentage of CM Professionals by Preference

Overall there are surprising differences in the percentage of CM professionals expressing one type of preference over another.  The following explores each preference set more thoroughly:

    • The Judging (J) or Perceiving (P) preference-set produced the most statistically meaningful difference.  A tally of 79% of the CM Professionals surveyed exhibited a leaning toward a Judging preference.  This may imply that CM professionals gravitate toward jobs or tasks that ask them to establish a level of structure and provides them with a working environment where concluding tasks and making decisions are the norm. 
    • This may stem from the multitasking environment most CM professionals
    • work where the completion of a task allows more focus on completing other tasks.  This is relatively steady from the 2003 survey where 76% were Extroverted and 24% were Introverted.    
    • The Sensing (S) or Intuition (N) preference-set also produced a statistically meaningful difference.  A tally of 69%
