Software developer - personality types


1 Software developer - personality types Lecturer: Peter Herner Supervisor: Hermann Lenhart Module: Software development in science SoSe14

2 Outline Foreword Myers-Briggs type indicator Prejudices against software developers M-B-TI: Features / types M-B-TI: Studies Comparison of the studies M-B-TI: Results summarized Interpretation of the results Type assumptions and criticism 2

3 Foreword In this lecture, psychological findings are related to software developers. The topic is the Myers-Briggs type indicator, based on the Jung theories ---> classifies behavior into types for a person! 3

4 Myers-Briggs Type Indicator: Why? Where does he comes from? Clearly presented figures for companies Human potential assessment by software developers Psychologists are interested in understanding the factors of career choice Very well known in the USA, for personal knowledge, career or partner advice Findings can help students / job seekers with career choice 4

5 Prejudices about software developers Software development is often viewed with false prejudices Math and logical reasoning are a must! Introverted, lone nerds who don't want to communicate 5

6 software developers ... who exactly? System and data analysts Programmers Project managers Help desk employees People involved in the planning, analysis, design, construction and provision of software systems 6

7 Myers-Briggs type indicator: What is it about? MBTI = test that determines the Jungian types + (4th property) Assigns certain personality traits to a person. A total of 4 traits are tested, each with 2 possibilities 16 possible. Results No right / wrong, just different types / preferences Automatically recorded, evaluated by certified people 7

8 1. Property: (E / I) Extroverts: - Attention is primarily to objects and people. - Obtain energy from the outside world (people / things) - Prefer to communicate / process information Verbal introverts: - Attention more to ideas / constructs - Obtain their energy, emotions and impressions from it - You process information internally. 8

9 2. Qualities: (S / N) Sensing: - Practically inclined, - Relying on common sense - Conservative and down-to-earth Intuitive: - Drawn to complex ideas and the theoretical implications, see / seek new opportunities - Are open to new things - Search for patterns and similarities 9

10 3rd characteristic: (F / T) Compassionate (Feeling): - Considering the human value / factor, - Personal measurement of values ​​is important Thinking: - Draw your conclusions and decisions objectively - Analytically seek the objective truth 10

11 4th characteristic: (P / J) Perceiving: - Try to open up possibilities - Are often seen as spontaneous - Collect information to find possibilities ---> decisions are not 100%, observe alternatives Decisive (judging): - Want to get things done - Are organized - Collect information for decision making ---> Pull the decision through 11

12 USA population type distribution INFJ, ENTJ, INTJ, ENFJ <3% ENTP, INTP, ESTP, INFP <5% ISTP 5.4% ENFP, ESFP, ESTJ, ISFP 8-9% ISTJ, ESFJ, ISFJ 11-14% ISFJ, ESFJ, ISTJ Other 5 16 types 6.25%? INFP, ESTP, INTP, ENTP ENFJ, INTJ, ENTJ, INFJ 12

13 studies: aerospace companies 1st study: carried out by Bush and Schkade with 58 participants Skilled workers involved in scientific programming in aerospace companies T (74%) and J (70%) very often ISTJ 25% INTJ 16% ENTP 9% 13

14 studies: Aerospace company 2. Study by Buie with 47 computer specialists employed by private companies, under contract with NASA, working on software related to our orbit. ESFJ (0%), ISFP (0%) and ENTP (0%) ---> confirms the hypothesis that I, N and T are overrepresented. ISTJ 19% INTP 15% INTJ 13% 14

15 Study: Insurance company 37 system analysts at a large insurance company a lot of introverts (57%), very many S (81%), T (89%) J (86%) strangely, NF combination not available in this small study ISTJ 35% ESTJ 30 % /// 15

16 Comprehensive large-scale study 1,229 software specialists from over 100 companies T (81%) I (67%) J (65%) very prominent ISTJ 23% INTJ 15% INTP 12% Research / development organizations, as well as companies that drive 8 state-of-the-art development --- > Often N instead of S Conversely in large organizations that mainly maintain and improve production software systems ---> Often S instead of N 16

17 Study: Students, employees 100 software developers (80% men 20% women) University students / civil servants / working for software companies, NT and ST a lot SF and NF a little Much S (67%) T (81%) Little I (33%) F (19%) INFJ ESFP ENFJ hardly available (1%) Combination STJ already 39% ISTJ 24% ESTJ 15% ESTP / ISTP 8% 8% Together over 50% 17

18 Cuba Study 103 Cuban software engineers, students and professors E (63%) I (37%), S (71%) I (29%) T (75%) F (25%), J (61%) P ( 39%) Outstanding: Many ESTPs ----> different from most previous studies. ESTJ 26% ESTP 13% ISTJ 10% 18

19 Cuba study INFJ and INFP at least with 1% followed by ISFP, ENTP and ESFJ with 2%. Most common combination: ST (54%); thereafter TJ (49%), ET (49%), ES (48%) NF least with only 9% .-----> similar to previous studies 19

20 Ranking summarized Aerospace - 1 ISTJ 25% INTJ 16% ENTP 9% Aerospace - 2 ISTJ 19% INTP 15% INTJ 13% Insurance ISTJ 35% ESTJ 30% /// Large study students / employees ISTJ 23% INTJ 15 % INTP 12% ISTJ 24% ESTJ 15% ESTP / ISTP 8% 8% Cuba study ESTJ 26% ESTP 13% ISTJ 10% 20

21 Interpretation of the results Different skills depending on the field of use advantageous Nonetheless overrepresented especially in SE: ISTJ 24%, ESTJ 15% Complete study constant: a lot of I, T, J ----> In the past, many mathematically and practically inclined people as pioneers (e.g. air / Space travel), out of date Good math skills are no longer absolutely necessary ----> necessary skills have changed 21

22 Further findings ISTJ often, but says little about success (career choice = / = success) Mostly teamwork ---> generally good diversity of many different types in a group. 22nd

23 Findings: I / E introverts currently dominate ----> could explain why software systems often do not meet user requirements. Nowadays software developers are needed almost everywhere (e.g. finance, administration, games) Software development has become much more user-oriented, developers have to understand what the user wants and discuss what is really needed. It is possible that in the future extroverts will be employed more than introverts in the software industry. Communication, adaptability and stress management have become more important. At the moment, planning, management and analysis are more dominant than programming. 23

24 Hardiman's Claim MBTI Allows Prediction of Who Will Be a Competent Programmer He observed that the vast majority of good software engineers were ENTJ, INTJ, ESTJ, ISTJ, ISFJ or ENTP ---> mostly NT or SJ combinations. Claims that NF-types tend to have problems with sequential / process-oriented thinking (necessary for designing / implementing software) 24

25 Assumptions for the types of ISTPs seem to be excellent programmers ----> find the approach to the problem quickly and find practical solutions INTPs ---> better in scientific programming, as well as important in the early phases of innovative projects, as they are good at finding problems (unfortunately not solved), like many academic researchers INTJs want to achieve something, but have little incentive to communicate with people ISTJs ---> good software engineers because they are persistent and work results-oriented. ISTJs and ESTJs plan more and are more organized ----> rather in management 25

26 Assumptions for the types of NTs more creative than STs, see the theoretical framework and the hidden details to recognize new possibilities Research and modern development ---> attract more NT software maintenance / improvement ----> attract more ST, because of them practical inclination 26

27 Criticism of the MBTI in the test study only available from certified MBTI consultants ---> very high license fee for evaluation + advice ----> not easily accessible to everyone Motivation ignored: money, recognition, independence, power, security Do I want to assess my personality when choosing a career? (= / = Competence!) Alternatively: unofficial, free variations in books / Internet Other, popular test: Big Five model (extraversion, openness, emotional stability, sociability, conscientiousness) 27
