Responsible Leadership Productivity and Performance

Question: Discuss about the Responsible Leadership for Productivity and Performance. Answer: Introduction Crevani, et al. (2007) have discussed about shared leadership. Nowadays, the practice of leadership has witnessed a movement where leadership positions are shared between two or more powerful individuals. There are ample amount of proofs of shared leadership in the present civilized society when it comes to the administration of corporate organizations, government organizations, or states. Thus, the authors have shared the view of leadership through collaboration of powerful leaders to help organizations to excel more. The section emphasizes on the complex nature of leadership position while supporting the idea of shared leadership.It states that new leadership environment is not a job for one man and requires a well qualified team to do the job (Conrad Nash, 2012). Discussion The authors through paper describes about sustainable leadership as it implies on the concept of working for the organization without losing other important elements in life. The modern society looks at the position of leadership to be challenging and time consuming. Hence, shared leadership can help to improve the leadership perspectives and increase the validity of leadership in organizations. Leadership techniques have always depicted about the practices of a leader in the industry.(Crevani et al., 2007) Hence, Shared Leadership focuses on today's needs of an individual and describes that leadership responsibilities can be performed without losing the essential elements of modern life. It discusses about the ways which can be practiced to improve the morality and effectiveness of leadership responsibilities. There is more than one example about past leadership where leadership was collective in nature. The concept of one-man army leadership is over according to the authors. They h ave said that this mannerism of leadership has a disadvantage of taking the leaders for granted as they are the sole saviours for organizations. Moreover, the article criticizes the concept of unitary leadership. It questions the power and the range of responsibilities handled by a single person. An example of Yahoo corporation can be taken where a single leader ruined the vision of the company and could not handle the pressure of responsibilities given to her. Marissa Mayer is the best example for the demerits for unitary command. She was supposed to save the company but could not handle the pressure of challenges and her narrow-mindedness ruined everything for Yahoo (Myatt, 2015). The authors focused on the unitary perspective of leadership and disagreed with the fact leadership is one mans job. Further,the concept of one-man power is questioned by the chapter with the help of general and real life examples. The chapter is liked and chosen because it wants to promote the idea of collective leadership, which could make leadership more productive and enjoyable at the same time. Leadership in the Age of Complexity: From Hero to Host There is a risk in leading things and it requires great control over the system. Wheatley Frieze (2011) have supported and celebrated the concept of leadership as hosting and not as a heroic deed. Moreover, they describe the major trait of a modern leader is to understand the complexity of situations and act according to it. Leadership has always been commemorated as action of heroic value. Author state that the world always hopes for a savior who could remove all the problems from life. People are habitual of being saved and doing nothing to save themselves. The report describes that this sort of attitude will not help or give strength to face challenges in future (Nixon et al., 2012). The section discusses that praying for a leader or depending upon a single individual can worsen the situation.Even a good leader can fail to handle complex situations and lead into total failure. Moreover, leadership and its responsibilities are complex as the problems of todays world are interconnected and complex.The complexity of problem is easy to be handled when collective efforts are made to solve problems. The authors want to say that people take responsibility and participate in the process of solving problems rather waiting for some leader to rise. They introduce the concept of leader as a host rather than a hero. Due to this ideology, there would be a collective force or team consisting of leaders and people to find solution to a problem. Example of CEO of Nokia Mr. Elop could be perfect as the fall of Nokia was considered to be one of his faults(Wheatley Frieze, 2011). During the age of android advancement, he faced the challenge of sustaining his company shares in the m arket and it was difficult for him to handle all the pressure. As a leader, he was talented but not expected to accept the defeat. Hence, as a result, Nokia failed disastrously. If there had being an application of host concept as discussed above, it would have survived easily with collective efforts (Surowiecki, 2013). Conclusion The author has clearly described the concept of new age leadership where a single handed process is a myth and leaders are considered and supported as normal human beings. The report has been selected because the concept can be applied to any sector and area of development. The power lies within people if they want to change their situations. References Conrad, D.
