Study of Myers-Briggs Types Relative to CM Professionals (2007)


has this personality type.  Upon closer inspection, an ESFP "uses their Sensing (S) and Judging (J) characteristics to gather specific, detailed information about others, and turn this information into supportive judgments. They are extremely good at reading others, and understanding their point of view.  The ESFJ takes their responsibilities very seriously, and is very dependable. They have a strong focus on the details of life. They see before others do what needs to be done, and do whatever it takes to make sure that it gets done." This seems to be good characteristics for CM professionals. 

An interesting note is that even with 87 responses, not 1 CM professional had the personality type of ESFP.  This was also true in the 2003 study.  This may imply that ESFP types do not gravitate to CM work.  Why would that be?  Upon closer inspection, an ESFP is a "spontaneous, optimistic individual. They love to have fun. They tend to become over-indulgent, and place more importance on immediate sensation and gratification than on their duties and obligations. They may also avoid looking at long-term consequences of their actions do not like structure and routine."  Given this information, it is reasonable to understand why ESFP may not want the duty bound and structured work that is a major part of CM work.

Note: comments by some of the participants to keep in mind are that there may be folks with certain Myers-Briggs types or those with certain preferences that do not respond to surveys.  This may make it hard to determine the true MBTI® distribution amongst CM Professionals. 

Comparing CM Professionals M-B Types for 2003 vs. 
This compares the 2007 results with the 2003 results.  Interestingly enough, we see remarkable similarities between results even after a 4 year gap.  As you can see from the comparative chart below, in 2003, INTJ was the number 1 Myers-Briggs type for CM professionals in both years with a slight increase from 27% compared to 32% in 2007.  ENTJ was in second in both years but slipped a little from 17% to 13%.  Surprisingly

ESTJ gained significantly from 5% in 2003 to 10% in 2007.   Many of the remaining MBTI® for CM professionals stayed unexpectedly the same. 

5: MBTI® of CM Professional Sample in 2003 vs. 2007
Comparing CM Professionals M-B Types to Overall Population 
This measure illustrates how CM professionals are spread across the 16 Myers Briggs  types (as a percentage) compared to the overall population. 
6: MBTI and CM Professional Sample Population vs. Overall Population

What can be noticed by this chart is that the distribution of the MBTI® of the CM professional sample does not align with the distribution of the Myers Briggs types of the overall population.  Several significant differences can be seen. 

According to these findings, the CM population (per the sample) is 32 times more likely
to be INTJ types than the overall population (32% for CM professionals and 1% for overall population). This is quite remarkable.  Also ESFP and ESTP appear to be very uncommon
in the CM population (0% and 2% respectively) compared to the overall population (13% and 13% respectively).   

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

Comparing CM Tools vs. CM Process 
The next question focuses on determining the differences in Myers-Briggs types between the CM process roles versus the CM tool roles?  Within the CM process role, this included CM Process Champions (local or enterprise level) and CM Managers.  Within the CM tool role, this included CM Tool Engineers, Build/Release Engineers, and CM Architects.  When tabulating the results, numerous people indicated that they do both process and tool tasks so this input was included in both the CM Process and CM
