Could One Transformational Leader Convert the Organization From Knowledge Based Into Learning Organization, Then Into Innovation？

This paper examines the role of transformational leadership in transforming an organization into a knowledge based, then into learning organization so that it becomes an innovative company. Important features of the leader such and ability to assist in developing and accommodating the implementation of knowledge management programs, learning organization concepts and innovation protocols are discussed in this paper. This paper demonstrates that shifting the organization to become a knowledge based and then to be learning organization and finally to become innovative company could involve some unique attributes of a transformation leadership. In that regards, the paper also demonstrates that organizations need first to create, capture, transfer, and mobilize knowledge before it can be used for learning and then for innovation. The paper will present a method of a studying how successful innovation leaders of companies could found themselves acting in three roles namely： knowledge leader, learning leader and then innovation leader.

Developing Universities into Learning Organizations

A number of companies and organizations consider that it is necessary todevelop into learning organizations in order to meet the challenges of rapidly changing world. Aftera review on the literature on the learning organization, there is no question that the concept isboth attractive and complex. There appears to be more consensus about that becoming a learningorganization is more of a journey than a destination. Senge identifies five key disciplines thatKelp organization to become a learning organization, and the disciplines mean commitment, focus,and practice. In recent years the concept of the learning organization is translated into theeducation sector. Today, more than ever, more and more people see education as the highest form ofleverage to improve society. As the highest form of the education sector, universities must try todevelop into learning organizations. But the process will be neither easy nor swift, and we shouldview the process not as a task to be completed, but as the ongoing work. Effective change andimprovement can only happen by conducting long-term practice involving teachers, administrators,parents, and students who have a common vision and work and live with a learning culture.
