Leadership abilities are susceptible to constant obsolescence and displacement due to today’s dynamic, complicated and uncertain business environments. Leaders must be flexible and agile enough to modify their actions and behaviors as conditions change to be effective. One of the essential success factors for managers and executives is their willingness and skill to learn from experience combined with changes in the environment and then apply that learning to perform successfully in new situations for their team’s effectiveness [
27]. Generally, there are various types of leadership at the organizational level to sustain their existence. Agile leadership is unquestionably critical for organizational sustainability regarding the digital economy’s fast speed of change [
28]. And also, in today’s business environment, the crucial participation of employees and team effectiveness are vital in enhancing organizational competitiveness and creativity.
2.1. The Link between Agile Leadership and Team Effectiveness
Agile leadership is responsive to emerging challenges or opportunities, and it works in quick development cycles of adaptation, learning and improvement [
29]. Agile leadership is a leadership approach that adapts to innovation processes in organizations and creates the ability of organizations to survive in competitive environments full of uncertainties [
30]. Agile leaders pay attention to work in a team instead of individually. Teamwork, in particular, has been extensively researched in management science. Therefore, agile management is most commonly practiced in teams, where human and cooperative components are critical to team effectiveness [
31]. Thus, agile leadership can be considered a set of practices that influence teams to achieve the desired goals. In organizations, leaders have various characteristics. Women leaders are also leading the organizations effectively [
32]. Agile women leaders impact organizational success and organizational performance [
33]. Organizational performance is a core concept in management, and most management activities are structured according to this concept. As research has shown, women leaders are characterized by a more participative management style compared to men [
34]. Therefore, women’s agile leadership is more immanently focused on team relationships and sustaining collaboration. Moreover, women in leadership roles are characterized by a more democratic approach to subordinates [
35]. This aspect of female leadership fits well with the agile paradigm requiring a focus on team collaboration. Agile women leaders have a strong motivational impact on employees. An increase in motivation leads to increased job performance [
36], which has a beneficial effect on female leadership.
The agile women leaders may guide the team and actively impact team behavior by developing, distributing and sustaining a guiding vision. To encourage team ownership of the vision and business goals, there must be ongoing group conversations and motivation with the team to build on the feelings. This will guide and inspire their teams. Such team interactions are critical in agile development, and the current emphasis on agile management has increased interest in how to structure small self-managing teams [
37] successfully. Women leaders, according to research, have better emotional intelligence which helps them to be more effective agile leaders. In the light of those studies, it should be emphasized that agile women leadership is critically important for modern enterprises.
There are some studies about leadership and team performance and effectiveness. A self-organized team operates under agile leadership [
38]. The variation in agility leadership figures expected by female civil servants was measured [
39]. There is close relationship between learning agility and employee potential and performance [
40]. It is stated that women have better performance than men as leaders [
41].
The majority of women leaders are doing an excellent job in their various organizations. There are some other studies on women leadership available in the literature [
33,
42,
43,
44]. However, previous studies ignore the discussion of the role of agile women leadership in team effectiveness. Thus, the below hypothesis is proposed:
Hypothesis 1 (H1). There is a significant, positive relationship between agile women leadership and team effectiveness.
2.2. The Link between Agile Leadership and Interpersonal Trust
Trust is defined as the voluntary assumption of risk concerning the future actions of others [
45]. It refers to a dual relationship between at least two parties [
46]. Thus, this reciprocal relationship is about making specific anticipations that take into account the positive consequences of actions taken by the other involved party [
47]. Trust is a dynamic interpersonal relationship between the parties involved, embedded in mutual assumptions manifested by certain attitudes [
48]. To summarize, in defining trust, we can assume that it is a mechanism that enables predicting the future behavior of other individuals in a particular relationship.
The analysis of trust in an organizational context can be conducted at different cognitive levels: interpersonal and intraorganizational. Intraorganizational trust is focused on trust in an organization or a company. On the other hand, interpersonal trust concerns mutual trust between employees [
46]. Mayer, Davis and Schoorman analyzed the factors that shaped interpersonal vertical trust in organizations and identified three major components that drive trustworthiness: competence, benevolence and integrity [
49]. Interpersonal trust can be considered horizontally, in relation to mutual relations linking co-workers of a given organization, and vertically, referring to the issue of trust between managers and subordinates [
50]. Vertical relationships are related to managers’ expectations of subordinates regarding the accomplishment of established work tasks and subordinates’ attitudes toward instructions, feedback or information provided by their supervisors. Vertical trust is identified in research as an element that supports organizational productivity, retention and adaptability [
50]. Employee trust in managers is an explanatory factor that affects their performance [
51]. Therefore, to ensure the efficient functioning of the organization, it is important to ensure high trust between employees and managers.
The interplay between agile leadership and vertical trust in an organization presents an important challenge in increasing the optimization of its functioning. One of the tasks of an agile leader is to build teams, which is usually driven by trust [
52]. Vertical trust and mutual respect are essential for rapid response to change or the flexibility inherent in the agile management paradigm and for continuous improvement of products and teams [
53]. Conversely, lack of trust is a key barrier to effective agile leadership [
54,
55]. Therefore, building vertical trust from an agile leadership perspective is an important enabler for effective organizational management. Moreover, empirical research confirms that trust is the basis for sound management of agile teams. For example, knowledge transfer management requires trust, which must be transparent and rapid to maintain agile potential [
56]. Additionally, it has been demonstrated that interpersonal trust in agile managed organizations significantly affects the innovative potential of the enterprise [
57]. The soft skills that contribute to managing people is one of the most important strengths of effective agile leadership [
21].
Vertical trust is also created as a result of agile leadership. The role of the leader in agile teams deals with adaptive support and includes providing direction, pointing out basic policies and procedures, fostering honest and constructive feedback and instilling collaboration [
54]. According to McAllister’s concept of building trust, there are two main sources of organizational trust. Trust can be cognitive, based on the other person’s competence, or affective, built on relationships and shared experiences [
58]. Therefore, the agile leader’s actions, which are a form of reinforcement of readiness for continuous change and improvement, build trust with managers based on shared experiences. On the one hand, the agile leader is competent, which is a basic requirement for leading a team. On the other hand, by closing short-term projects, the trust building process goes much faster than in traditional organizations. Especially since, in light of Schoorman, Mayer, and Davis [
59], trust in a leader is built primarily on competencies; the competencies of an agile leader are a core element in establishing team relationships [
59]. Feminine leadership style more often prompts employees to dialogue and build relationships, which favors building trust between employees and the leader [
60]. Employee trust in the leader is seen as a necessary factor for the success of charismatic leadership [
61]. We assume that trust also plays a vital role in agile leadership. Moreover, it was noticed that an increase in trust in the leader took place when they showed caring traits toward their subordinates [
62]. Women leaders have traits that encourage trust-based relationships, such as empathy and communicativeness [
63].
Agile leadership and interpersonal trust are inextricably linked in the interdependent connection between the manager and team members. Therefore, we assume that agile leadership fosters interpersonal trust in organizations.
Hypothesis 2 (H2). There is a significant, positive relationship between agile women leadership and interpersonal trust.
2.3. The Link between Interpersonal Trust and Team Effectiveness
Efficiency, in management terms, means improving the processes involved in the operation of a business [
64]. Team effectiveness is defined as the outcome of group collaboration [
65]. Thus, team effectiveness refers to the ability of that team to achieve its goals. This constitutes the basis for the success and productivity of such a team.
Previous research findings confirm that trust provides a platform for developing effective collaborative relationships in organizations [
66]. Previous studies especially demonstrate how important interpersonal trust is to organizational performance [
51]. Research on remote organizations highlights a link between team effectiveness and interpersonal trust [
65]. Moreover, prior research indicates that trust in the leader increases the effectiveness of the leader in the team [
67]. From the above-mentioned examples, it can be concluded that interpersonal trust, especially vertical trust, contributes significantly to team effectiveness. In particular, it seems that trust in the agile leader helps to respond quickly to changes, adapt flexibly to situations and build sincere relationships based on mutual feedback. Therefore, we hypothesize that interpersonal trust contributes significantly to agile team effectiveness. The hypothesis adopted is:
Hypothesis 3 (H3). There is a significant, positive relationship between interpersonal trust and agile team effectiveness.
2.4. The Mediating Role of Interpersonal Trust
Previous studies confirm that trust in the leader mediates the team effectiveness relationship [
68]. Given the evidence indicating relationships of vertical trust with effectiveness and with agile leadership, we postulate that trust in the leader will mediate this relationship. An employee who trusts the leader carries out tasks without waiting for an individual reward. In teamwork, the expected benefit from this relationship, according to SET, will be the collective result of team members [
11]. Interpersonal trust in the agile manager–employee relationship allows the leader to make decisions based on trust. It means that the leader knows that the employees will perform their tasks to the best of their ability. Trust in the leader causes the employee to perform tasks and be involved in work, regardless of whether they do not immediately gain benefits. The employee knows that their tasks are aimed at the implementation of the company’s strategy and the manager’s vision. Relationships based on trust make the employee and the team try to achieve the best possible results, which are necessary for the company to adapt to the changes.
Interpersonal vertical trust is an underlying mechanism that transmits the relationship between agile women leadership and team effectiveness. This relationship, in our view, can be explained precisely through interpersonal trust being an important explanatory factor for this relationship. Therefore, in this study, we hypothesized that trust in the leader is a mediator of the relationship between agile women leadership and team effectiveness. The hypothesis, therefore, is as follows:
Hypothesis 4 (H4). Interpersonal trust has a mediating role between agile women leadership and team effectiveness in enterprises.
