== '''Abstract''' ==

According to the American Psychological Association (APA), the definition of a personality trait is "''a relatively stable, consistent, and enduring internal characteristic that is inferred from a pattern of behaviors, attitudes, feelings, and habits in the individual. The study of personality traits can be useful in summarizing, predicting, and explaining an individual’s conduct...''" <ref> APA Dictionary of Psychology. Retrieved from: https://dictionary.apa.org/personality-trait </ref>. Personality traits greatly influence an individual's behavior, attitudes, and decision-making processes. Understanding and recognizing the influence of personality traits at work is crucial since they directly affect a person's performance and effectiveness inside an organization. This is crucial while managing projects because effective teamwork, communication, and conflict resolution are necessary for success. 

Effective management of personality traits can lead to improved collaboration and communication among team members and better handling of conflicts. Managers can assign tasks and responsibilities that capitalize on each team member's strengths while being aware of their deficiencies, resulting in a more effective and productive team dynamic. Additionally, by adapting their management style to each team member's personality qualities, managers can increase team member motivation and job satisfaction.

It is critical to have a comprehensive framework for evaluating and comprehending personality features to identify and capitalize on these traits in the workplace. The Hexaco Model is one such model that offers a structured method for comprehending personality and predicting behavior. Since the 1990s, there have been two predominant views about the question of personality structure, namely the "Big Five" or "Five-Factor Model". Both of these positions are currently supported by much evidence to be incorrect. The HEXACO model, a six-dimensional framework, is supported by the outcomes of investigations into personality structure. <ref>  Ashton, M.C. and Lee, K.

The HEXACO Model of Personality Structure is a widely accepted framework for comprehending and measuring individual personality differences. As an alternative to the OCEAN model, this model holds six dimensions divided into Facet-Level Scales, each representing a broad aspect of personality. 

'''Honesty-Humility (H)''' is one such dimension that signifies the extent to which individuals are humble and unassuming compared to those who exhibit boastful and pretentious behavior. In assessing one's level of Honesty-Humility, factors like Sincerity, Fairness, Greed Avoidance and Modesty come into play. People who score high in this dimension demonstrate a tendency towards humility coupled with traits such as fairness and sincerity. They also eschew arrogance in favor of valuing interpersonal relationships rather than seeking personal gain or prestige. In contrast to these qualities are low-scoring individuals who may engage in self-promotion or manipulation while prioritizing pursuits of power and status<ref name="hexaco">Ashton MC, Lee K. Empirical, theoretical, and practical advantages of the HEXACO model of personality structure. Pers Soc Psychol Rev. 2007 May;11(2):150-66. doi: 10.1177/1088868306294907. PMID: 18453460.. Retrieved from https://journals.sagepub.com/doi/10.1177/1088868306294907 </ref>. 

'''Emotionality (E)''' is a fundamental dimension in characterizing individuals' personal traits with respect to their experience and expression of emotions as well as their ability to control them. The measures underlying this classification constitute fearfulness, anxiety, dependence, and sentimentality. Those maximizing scores on this measure are generally labeled warm-hearted personalities embodying compassionately sensitive attributes coupled with susceptibility to being moved by sentiments. Low-scoring individuals exhibit traits such as unemotionalism, detachedness and rationality. They tend towards insensitivity regarding other people's emotions while being highly stoic in their approach to life. Empathy seems fleeting for them making them appear uninvolved with emotional sensitivities of others <ref name="hexaco" />.

'''Extraversion (X)''' as a metric aims at defining a person’s retention level when it comes to sociable behavior (or lack thereof). Measured through four discernible categories - Social Self-esteem, Social Boldness, Sociability and Liveliness. Individuals that obtain high scores in this dimension often acquire attributes such as being outgoing, energetic and assertive. Their temperament reflects those of sociable, confident individuals who have highly expressive nature. These individuals prefer interacting with people and excel in social situations. People scoring low on this scale tend to be more introverted, reserved, less assertive, and talkative than their counterparts. They may appear quiet or unapproachable and tend to enjoy solitude while occasionally spending time with close friends<ref name="hexaco" />.

'''Agreeableness (A)''' can be evaluated through the traits of Forgiveness, Gentleness, Flexibility, and Patience. Individuals who score high on this spectrum display cooperative behavior stamped by compassion and empathy for those around them. Valuing peaceful associations forms a critical aspect of their personalities that adds further value to their friendliness and amiability. In contrast, people with low scores exhibit competitive qualities marked by aggressiveness and confrontation while holding limited regard for others' interests <ref name="hexaco" />.

'''Conscientiousness (C)''' refers to an individual's ability to be dependable, responsible and disciplined. This facet includes traits like being well-organized in managing tasks efficiently; displaying diligence by putting forth maximum effort into assignments; taking a perfectionist approach where quality of work matters most and being prudent in finalizing decisions after thoroughly analyzing outcomes. Individuals scoring lower on Conscientiousness tend towards impulsiveness, carelessness marked by lackluster planning leading them into adverse scenarios requiring quick fixes. Inclination towards impulsive behavior, lack of organizational skills, and carelessness are common traits associated with an individual scoring low on this dimension. Their decision-making style is often rash and not well thought out leading them to be perceived as irresponsible or lacking discipline.  <ref name="hexaco" />.

'''Openness to Experience (O)''' is a metric that entails creativity appreciation, inquiry drive, non-conformity mindset fostering an individual's imaginative flair for uncharted territories. Individuals scoring high on Openness to Experience are typically characterized as imaginative, curious and open-minded. They possess a proclivity for creativity, intellectualism and enjoy seeking out novel experiences and ideas. Such characteristics render them as innovative individuals with progressive outlooks. In contrast, low scorers often display conservative tendencies that border on being traditionalists while closed-mindedness is not uncommon among them. With little inquisitiveness about new ideas or experiences, they tend to lack imagination and may prefer the comfort of familiar territory  <ref name="hexaco" />.

It is worth mentioning that the HEXACO model, which has become increasingly popular in personality psychology and related areas, derives its name from the six factors it encompasses.

===The HEXACO Model of Personality Structure as a measurement tool===

[[File:HEXACO_test.png|450px|thumb|right|Figure 1: The HEXACO Model test results <ref name="hexaco.org test">Ashton MC, Lee K. THE HEXACO PERSONALITY INVENTORY - REVISED. Take the HEXACO-PI-R. Retrieved from https://survey.ucalgary.ca/jfe/form/SV_0icFBjWwyHvJOfA </ref>. ]]

Based on the theoretical descriptive model, several researchers have developed questionnaires and scales to measure and interpret personality traits and correlations between behavior and personality. Among others are the following HEXACO measurement tools:

* HEXACO Personality Inventory - Revised (HEXACO-PI-R)  <ref name="hexaco 140">Lee, K., & Ashton, M. C. (2012). The H factor of personality: Why some people are manipulative, self-entitled, materialistic, and exploitive—and why it matters for everyone. Wilfrid Laurier University Press. </ref>.
* HEXACO-60 Personality Inventory <ref name="hexaco 60">Ashton MC, Lee K. The HEXACO-60: a short measure of the major dimensions of personality. J Pers Assess. 2009 Jul;91(4):340-5. doi: 10.1080/00223890902935878. PMID: 20017063.. Retrieved from https://pubmed.ncbi.nlm.nih.gov/26804579/ </ref>.
* HEXACO-100 Personality Inventory <ref name="hexaco 100">Lee K, Ashton MC. Psychometric Properties of the HEXACO Personality Inventory. Multivariate Behav Res. 2004 Apr 1;39(2):329-58. doi: 10.1207/s15327906mbr3902_8. PMID: 26804579. Retrieved from https://pubmed.ncbi.nlm.nih.gov/26804579/ </ref>.

All tests assess personality concerning the HEXACO factors but are done differently with regard to the amount and appearance of question items. They vary from long-sentence questions in the HEXACO-PI-R to brief phrases in the HEXACO-60 Personality Inventory. Further, some tests are commercial, and others are created for non-commercial research purposes. The best validated HEXACO measures in the questionnaire tradition are the HEXACO-PI-R test. However, for research settings where time is of the essence, the HEXACO-60 Personality Inventory is also frequently used.

The HEXACO-PI-R is developed by Michael Ashton and Kibeom Lee and is a 140-item questionnaire. Each item is a sentence that is rated using the Likert scale, a scale from 1 to 5 where one is equal to strongly disagree and five to strongly agree. The items fall under the six HEXACO factors, but the factors are further categorized into facets, giving a total of 30 facets. The HEXACO-PI-R is developed so the questionnaire can be assessed in two forms; a self-report called the S-form and an observer report called the R-form, getting both an internal and an external perspective of a person's personality and a comparison here off.    <ref name="hexaco.org">Ashton MC, Lee K.

=== Origin and Development of the HEXACO Model of Personality Structure  ===

A psychological model of personality called the HEXACO Model of Personality Structure was first presented by Belgian psychologists Kibeom Lee and Michael C. Ashton in the late 1990s. In order to solve some of the shortcomings of the Big Five model, the model was developed as an extension of the Big Five Personality Traits. Based on the notion that personality can be described by six broad dimensions or characteristics rather than simply five, the HEXACO Model was developed <ref name="hexaco.org history">Ashton MC, Lee K. THE HEXACO PERSONALITY INVENTORY - REVISED. History of the Inventory. Retrieved from https://hexaco.org/history </ref>.

A thorough examination of personality descriptors in several languages served as the foundation for creating the HEXACO Model. The study's goal was to list the most frequent and significant personality qualities that individuals use to describe others and themselves. The HEXACO Personality Inventory, a self-report questionnaire that assesses the model's six dimensions, was created using the findings of this study <ref name="hexaco.org history" />.

The model was later revised to include changes to the way certain traits were defined, as well as changes to the scoring of the test. The primary purpose of these modifications was to improve the model's suitability for usage in a wider variety of cultural contexts. The HEXACO Personality Structure Model's original creators collaborated with additional experts in the field of personality psychology to create the updated version. Reviewing the body of research on personality structure and input from users of the original model helped shape the development of the new model. The updated model was created to provide further validity, dependability, and accuracy in assessing personality structure and more practical applications in various industries, including business, education, and healthcare <ref name="hexaco.org history" />.

=== The HEXACO Model of Personality Structure vs. The Big Five (OCEAN) Model ===

The leading model of personality traits for many years has been the Big Five (OCEAN) model. This framework is acknowledged and accepted by scientists across different cultures and languages. Nevertheless, there have been criticisms about its ability to capture a complete understanding of human personality <ref name="beyond">Leaetta M. Hough, Frederick L. Oswald, Jisoo Ock. Beyond the Big Five: New Directions for Personality Research and Practice in Organizations. Annual Review of Organizational Psychology and Organizational Behavior 2015 2:1, 183-209 Retrieved from https://www.annualreviews.org/doi/abs/10.1146/annurev-orgpsych-032414-111441 </ref>. Therefore, an alternative, known as the HEXACO model of personality structure was developed. With its ability to predict ethical behavior and reduce the occurrence of unethical actions, research has shown that the Honesty-Humility dimension is a vital component of human personality. On the other hand, the range of emotional experiences that comprise Emotionality makes it an essential aspect of understanding individuals' emotional makeup. Thus, unlike The Big Five model that lacks these dimensions, HEXACO offers a more detailed approach to comprehend human personalities; hence making it pivotal in various fields such as psychology, social science research, and business. <ref name="beyond" />

== '''Application''' ==

The HEXACO model has many applications, but in the context of project management, the answers to a HEXACO questionnaire can be beneficial when assembling and leading a project team. The organization depends on the project team to meet predetermined project goals since people are essential to a project's success.

=== The HEXACO Model in Project, Program and Portfolio Management ===
Recent years have seen a rise in interest in the HEXACO Model of Personality Structure due to its potential use in several industries, including project, program, and portfolio management. The model offers perceptions of a person's personality attributes, which can be helpful in project planning and execution. The application of the HEXACO Model to project, program, and portfolio management will be covered in this part.

'''Project Management:''' Understanding team members' personalities is essential for project management to enable appropriate work delegation, collaboration, and communication. Project managers can utilize the HEXACO Model to determine the personality qualities of their team members and then use that knowledge to foster a positive and effective work environment. For instance, those who perform well on the Honesty-Humility scale may be good team players and collaborators. However, those who perform well on the Emotionality scale may be more sensitive to criticism and need more support. Project managers can adapt their leadership style and communication strategy to match the needs of each team member and enhance team performance by being aware of these characteristics <ref name="hexaco" />.

'''Program Management:''' The HEXACO Model can be used in program management to evaluate the compatibility of various programs and projects to ensure they align with company goals. Programs with high levels of Extraversion may need more outreach and marketing efforts, whereas programs with high levels of Emotionality may need additional resources and support. Program managers may allocate resources wisely, prioritize programs, and guarantee effective outcomes by being aware of the personality qualities of the programs and projects <ref name="hexaco" />.

'''Portfolio Management:''' The HEXACO Model can offer insightful information about an organization's culture and the personalities of essential stakeholders in portfolio management. Portfolio managers can customize their communication and decision-making strategies to achieve buy-in and support for portfolio objectives by studying the personality attributes of stakeholders. While stakeholders with high levels of Agreeableness may be more likely to support initiatives that align with the organization's values, those with high levels of Conscientiousness may be more detail-oriented and want a detailed explanation of portfolio projects <ref name="hexaco" />.

=== Organizational Behaviour ===
It has been demonstrated that the HEXACO Model has significant consequences for various outcomes, including leadership, teamwork, and job performance. It has been widely employed in the field of organizational behavior. For instance, studies have shown that people with high Honesty-Humility are more likely to be great leaders because they are less inclined to act selfishly and more likely to act in the organization's best interests. Additionally, studies have indicated that very emotional people are less successful leaders because they may be more susceptible to burnout and emotional tiredness. The HEXACO Model has also demonstrated effectiveness at forecasting collaborative behavior and results. For instance, people with high levels of agreeableness are more likely to cooperate. However, highly conscientious people are more likely to accept responsibility for their actions and finish what they start <ref name="hexaco organization">Breevaart, K., & de Vries, R. E. (in press). Followers' HEXACO personality traits and preference for charismatic, relationship-oriented, and task-oriented leadership. Journal of Business and Psychology. Retrieved from https://findit.dtu.dk/en/catalog/5e14953ed9001d01925a9bf7 </ref>.

=== Personnel Selection ===
The HEXACO Model has also been used in personnel selection to find appropriate people for particular positions or tasks. For tasks requiring diligence, responsibility, and organization, people high in conscientiousness are frequently viewed as good prospects. In contrast, people high in extraversion are frequently viewed as promising candidates for roles requiring sociability and assertiveness. Additionally, the HEXACO Model has been applied to leadership selection processes. People with high Honesty-Humility scores are frequently viewed as the ideal candidates since they are less inclined to act selfishly and more likely to act in the interests of the group as a whole <ref name="hexaco" />.

=== Well-being Research ===
In order to explore the role of personality in subjective well-being, the HEXACO Model has been employed in well-being research. For instance, studies have revealed that very emotional people tend to feel negative emotions more intensely. However, highly honest and humble people tend to be happier because they are less inclined to act selfishly and more likely to engage in actions that benefit others. Additionally, studies have indicated that people with high levels of conscientiousness have lower stress levels and better physical health. In contrast, people with high levels of openness to experience have higher levels of creativity and cognitive flexibility <ref name="hexaco wellbeing">Buca, A., Calin, M., & Mincu, L. (2016).

Retrieved from https://journals.sagepub.com/doi/10.1177/1088868306294907 </ref>.

== '''Criticism and Limitations''' ==

Like any personality model, the HEXACO model has its limitations and critics. Some of these limitations and criticisms are common for personality models, such that the HEXACO model does not capture the full complexity of human personality <ref name="beyond" />. Another criticism of the HEXACO Model is that while the model has been used in various cultures, there may be cultural differences in the expression of personality traits that the HEXACO model does not fully capture <ref name="commentary">Open peer commentary and author’s response. (2020). European Journal of Personality, 34(4), 511–590. Retrieved from https://doi.org/10.1002/per.2284 </ref>. Also, since the HEXACO Model is based on self-reported data when using the questionnaires, the data might be subject to various forms of bias, such as individuals may underreport, overreport or have difficulty accurately assessing certain personality traits, which impacts the validity of the model <ref name="commentary" />.

One of the main criticisms of the HEXACO Model of Personality Structure is whether the HEXACO Model provides a better framework for understanding and measuring personality traits than the well-established Big Five (OCEAN) model <ref name="commentary" />. Due to the inclusion of the Honesty-Humility factor, which is thought to be particularly useful in predicting counterproductive workplace behaviors, the HEXACO model has been marketed as superior to the Big Five model. An important subject that, according to critics, has not been adequately addressed is whether the HEXACO model and its factors and facets provide a more substantial validity or an overall better-explained proportion of variation than the Big Five (OCEAN) model related to predicting workplace behavior relevant to personality <ref name="beyond" />. The understanding of the predictive potential of personality measures is constrained by the use of criteria measures in studies that demonstrate support for the HEXACO model that is susceptible to standard method variance or suffers from other types of contamination and deficiency. Noting that the HEXACO model, like the Big Five model, does not encompass all personality traits, it is also significant to underline that a more profound comprehension of personality at a facet level is required <ref name="beyond" />.
