Introduction
In this 21st century, change management has been the 'flesh and blook' in both private and public sector. The impact of change is also significant in the emerging industries. All sectors need to be positively responded to current trends in terms adoption of innovative ideas and effective and efficient work processes (Barber, Donnelly & Rizvi, 2013).
Change is a continuous and fast process that involves three phases. The first phase is unfreezing which refers to creating readiness to change by stating the importance and benefits of change. It is necessary to every individual and organization to leave the current state of comfort. Second phase is moving, where the change players have to move forward and enabling change adoption. The last phase, on the other hand is refreezing, where new changes or norms in the organization are widely accepted and routinise the changes (Awour & Kamau, 2015).
According to Akinbode & Al Shuhumi (2018), to successfully manage change, there is a need for an organization to have skillful and effective leaders and they on the other hand, need to understand the change management process. They are also need to equip themselves with an appropriate leadership styles and traits so that these leaders are able to initiate and guide the change process successfully.
It is undeniably that the basic principles and practices of leadership and management have been significant all this while (Dike, Odiwe & Ehujor, 2015;Darwish et al., 2020). However, this relationship is seen becoming more complex due to the dynamics of the 21st century organizations and the new global economy. To comply that, leaders that are able to make quick decisions, are up-to-date with the current technologies pace, great communicator between the superior and subordinates and most importantly, skilled change agents who manage to use persuasion reasons to get the followers' support on organizational change implementation. Hence, this paper aims at reviewing the relationship between transformational leadership style and managing change in organizations.
Based on the Review of Change Management in United Nations Systems Organizations by UN Joint Inspection Unit (2019), it can be concluded that 20 percent of 26 organizations, the change management has not been fully appreciated or understood in the reform, and where some organizations have done so in an ineffective method. Meanwhile, 30 percent of the reform showed evidence of incorporating the majority of the key elements of change management where it was illustrated a direct relationship between the presence of key elements of change management and the depth which they are applied.

Literature Review
The study started the discussion with organizational change, leadership and followed by focusing on transformational leadership. Finally, the role of leadership in change management was reviewed from past literature reviews.

Organizational Change
In Hussain et al (2018), organizational change refers to the explanation of the movement of an organization from a current known state to an unknown desired future state. Meanwhile, Jones (2010) defines it as the process by which organizations move from their present state to some desired future state to increase their effectiveness. Gerwing (2016) revealed in his studies that previous researchers in the nineties, Porras and Robertson reviewed the theories and literature generally on organizational change. The researchers also conducted a deep research on the field of organizational change. There are two kinds of organizational change, which is 'planned versus unplanned change' and 'first order versus second order' change. According to Porras & Robertson (1992), the difference between planned change is a careful verdict or process to progress the organization while unplanned change respond to external influences such as new technologies or competitors that affect an organization's main business. To face that situation, organizations must react proactively in order to response in a more adaptive manner towards planned change.
Continuous improvement can be represented by first-order change. It may cause less fundamental impact in the business as it is merely the changes or adjustments in the existing systems or processes. Changes in the hierarchy of an organization is one of the example. However, second-order change can be seen more drastic and crucial. It is also interrelated with to unplanned change. Porras & Robertson (1992) termed this pattern of change as 'revolutionary change'.
In Kuipers, de Witte & der Voet (2013) mentioned that organizational change aims at making some and obvious changes in the organization. To identify whether there is a success in an organizational change, previous researchers or stakeholders would look into the different perceptions on certain change initiatives as the term success is subjective. It was actively debated that a successful organizational change will results in organizational performance, while other researchers viewed successful change is as a result of supportive employees and their attitudes toward change.

Leadership
Leadership is defined as the ability to influence a group of employees' values, beliefs, attitudes and behavior (Ganta & Manukonda, 2014). A leader with strong leadership skills can easily motivate and influence the employees of the organization and apply effective changes to the organization. Organizational change is a 'no-show' if there is an absence in effective leadership (Atkinson, 2015). The reason behind this is because there are no leaders that motivate and lead the organization's employees as well as provide clear direction for the organization (Hao & Yazdanifard, 2015).
According to Bass (1985), leaders must become the change agent in promoting change by creating vision. The created vision on the other hand must be clearly defined, understandable and attainable. Leaders must possess a clear understanding of the strategic objectives for their organization, identify actions needed to achieve the objectives and conduct an analysis of the organizations existing ideologies (Belias & Koustelios, 2014).
The role of leading changes is on a leaders' hands. Leaders help people to develop necessary skills to facilitate them in coping up with the changes in an organization (Awuor & Kamau, 2015). An effective and strategic leaders must be attentive towards the formulation, implementation and sustaining the change efforts. In this twenty first century with the vast technological advancement, in order to make organizations gain the competitive advantage than their competitors, organizations should be more adaptive to change. Singh (2011) believes the adaptive to change can only be achieved through organizational leadership.
There are two famous types of leaderships, namely transactional and transformational leadership. In Carter, Armenakis, Field & Mossholder (2012), a transactional leader is one who gives reward in the form of promotions, raised pay, desired change of duties and many others to those who follows. Punishment will also be given on the other hand to those who did undesirable behaviours. Meanwhile, transformational leaders change people around them by using their knowledge, expertise and vision. This will encourage full participation in changing others and the change will remain even when the leader is out of sight.

Transformational Leadership
Previous researchers, Holten & Brenner (2015), did a study on leadership styles which are transformational and transactional and followers' change appraisal, both directly and indirectly through manager engagement. The researchers studied two Danish organizations, tracking the planned implementation of team organization at two different times. The findings of research is leadership styles and manager engagement is crucial in promoting such appraisal and consequently supporting positive processes and outcomes of change.
Transformational leadership may be an effective approach to enhance followers' positive appraisal of change. The entire process of change may be benefited from the long -term and short-term positive effects of managers' increased potential. Apart from that, the awareness of managers' role in communicating important information, interpreting the individual consequences, and working actively and positively towards the change may be an area of positive investment for organizations in change. Hence, a long term focus on managers' abilities to perform both transformational leadership and to engage themselves specifically in the change.
In Belias & Koustelios (2014), strategic leadership needs to be transformational if it is aimed to serve the organization. Their studies stated that transformational leadership style is suitable for change culture because change culture needs much energy and commitment to achieve outcomes. Transformational leaders emphasize that change is accomplished through the leader's implementation of a unique vision of the organization through powerful personal characteristics designed to change internal organizational cultural norms.
Strategic leaders have the best perspective where the knowledge is concerned to see the dynamics of the culture, what should remain and what needs alteration. Past researchers mentioned in their studies that "Leaders is the art of mobilizing others to want to struggle for shared aspirations". Therefore, it is crucial for leaders to be highly skilled in change management process if they want to be a successful change agents. The main task of management nowadays is the leadership of firm change. Good strategic change leadership involves instrumental roles and big interpersonal skills. Good change leaders find out the important dimensions of change leadership. Being able to balance the roles depends mainly on whether a leader has certain qualities needed for good change leadership which supported by strong skills.
Meanwhile in Faupel & Sub (2018), their research supported that a transformational leadership can give positive effect on employees' change-supportive behaviour during the implementation of organizational change. An effective leadership in the organization has helped to driven the motivation of the employees to support change. This has intensify the effort when the employees engaged in the process and there is an encouraging change consequences through transformational leadership within the organization. Transformational leadership is said to be the only way to achieve higher levels of valence and work engagement as it can give the true picture of the benefits and meaning of a change for employees.
In another journal article related to leadership style in organizational change management, various leadership styles have been studied that can see as a change agent or change management promoter. Mansaray (2019) reviewed various types of leadership such as authoritarian leadership, transformational leadership, laissez-faire, servant-leader, transactional leadership and many more. To his findings, the most supportive style is transformational leadership. It is hugely supported by Bass & Riggio (2006); Eisenbach, Watson, & Pillai (1999) where in order to manage organizational change, transformational leadership is the most suitable style. This leadership style is at the best position to face the trials and difficulties of the emerging administrative practices because transformational leader has the capability to drive his group in delivering and providing more than the organization expected.
In another study by Wanza & Nkuraru (2016), the importance of strategic management in organizations nowadays has increased widely and become the most crucial elements. Strategic outcomes depend on the managerial proficiency and key management functions that involves learning to delegate, planning, organizing, clear communication, employees motivation, adaptation towards change and constant innovative ideas generation. In order to ensure change management to be effective, leaders in an organizations need to successfully motivate their teams or subordinate so that there will be high participation rate in the change management process. This, in hand is aligned with other researchers' view where every manager needs to acquire good leadership and managerial skills to induce workers to change directions (McLagan, 2002). Constant motivations and guidelines within the organization should be led by a leader or manager as it can also improves employees' performance and hence indirectly, improving organizational performance.
One of the findings of their study is leadership in an organization provides direction as a leader will influence others to follow. A positive attitude from the leaders or managers will critically affect in behavioural changes and performance of the employees ar work. This is because a leader or manager considered quality if he or she evaluates the relationship between leadership style and employee levels of organizational commitment. The type of leadership style is similar with transformational leadership style.

The Relationship between Leadership Role and Change Management
From the review done by the United Nation (2019), specific needs of the organization need to be tailored and informal mechanisms can structure dialogues and engagement with the staff as readiness assessments do not have to be huge and costly.
Among the critical success factors listed in the review is senior leaders need to contribute to the change. Apart from leadership by the executive head alone, a clear governance structure for change management-related reforms is also necessary. This is to ensure that the process can be influenced by the relevant stakeholders limited by their role and structure depending on organizational configurations and the type of reforms. Moreover, expertise or capacity in change management across staff is also required. The selection and use of change agents across an organization in a reform is critical as reforms that use change agents across an organization are twice as likely to have good depth across the key elements of change management United Nation (2019). Therefore, there are specific leadership styles or traits that are suitable for effective organizational change.
There is an increasing number of recognitions where most successful implementation of change is impacted by good leadership practices, styles and behaviours. There are some agreements among past researchers on significant role of leaders' behaviours towards change success. Strategic renewal is also seen as a consequence of leadership behaviours that build effective relationships with followers and engage them with the strategic vision and goals through high levels of involvement and participation (Kuipers et al, 2014;Higgs & Rowland, 2011;Bamford & Forrester, 2003). Furthermore, Mwakisaghu (2019) studied how leadership act as strategic management change determinant. The adoption of changes by strategic management is build upon trust, organization culture, learning, team work communication and leading. This is in line with Atkinson (2015) view on strategic management changes can take place if there is effective leadership in the organization. The determinants stated by Mwakisaghu fits with Atkinson's view as it is necessary for leaders to provide a clear direction for the organization as it helps to motivate and drive the employees in the organization. (2019), trust shows significant effect to determine the effectiveness of leadership. When the followers or subordinates trust their leader especially to the changes that to be brought in the organization, they tend to follow as they believe him or her may lead them to the right path either for themselves and/ or the organization. Other than that, leaders with strong leadership skills will shape a positive culture in the organization and thus, influences the behavior and attitude of the employees in the organization for the better (Ionescu, 2014;Schein, 2010). Both leaders and the employees should join training programs as further learning may improve their ability to perform well in their job. This can also help to facilitate the effective desired change implementation and at the same time enhance the productivity and performance of the employees. Lastly, Gilley, Dixon & Gilley (2008) in Mwakisaghu (2019) indicated that leaders who wish to facilitate effective change in the organization should encourage employees to collborate and communicate with each other. Even the top management can learn and consider the strong points given by their employees.

Discussion and Conclusion
Based on findings, researcher synthesizes some opinions and ideas gathered from literature reviews from different scholars and academicians.
From the past researches reviewed in this paper, I can conclude that change management is crucial in every organization especially in facing the challenges in 21st century as the issues nowadays are not as conventional as the last decade. Organizations must adopt changes within to meet the fast-changing environment especially in business and also in serving public or communities.
Every challenges and issues varied and the approach to overcome need to be tailor-made. In approaching towards effective problem solving and decision making, the leader or manager must first identify the issues and need to educate and convince the subordinates or followers to accept organizational change. Their acceptance towards change proves that the manager applies an effective leadership for managing change. To be a better leader, one has to undergo training so that the skills are improving. It is even better to include the employees as well to join the training as it can motivate them and hence, improving the productivity of the organization.
Leadership style varies according to individuality of the manager himself, but it brings similar vision of bringing change among the subordinates in the organization. The topic of leadership is highly discussed among scholars and it is still being debated even in this century. This also proves that good and effective leadership results in better management in organizations especially for promoting change and maintain the openness culture.

Conclusion
This paper aimed to evaluate how prior researches had been dealing with organizational change in recent years taking in account leadership role. The first purpose was achieved with finding from the research reveals the leadership dimensions suggested by prior researchers.
The key findings indicated that Transformational Leadership emerged as one of the important dimensions in recent studies. There are indications that proof a strong relationship between effective leadership and significant impacts on successful organizational management. Hence, the second purpose of this study was met where the variables could be practically used as corporate future direction indicator by top management. In closing, our objectives for this research have been achieved. Despite these findings, we hope to trigger more studies on this area as we believe that the identified dimensions are a strong indicator of a variety of different industries, yet we do not want to limit to them. More research can be carried out to uncover other moderators and illustrating how these performance measures affects corporate future direction even more clearly in future extensions of this research.
