Abstract Lately, organizations have become increasingly aware of the value of managing their organizational learning and knowledge. Thus researchers have investigated those processes extensively. Still something is missing in the current discussions of organizational knowledge: organizations do not just learn; they also forget. Knowledge management is creating processes not only for learning and retaining what is important but also for avoiding or unlearning what is not important. Forgetting, like learning, is not simple: it may be detrimental or beneficial, accidental or purposeful. By the way, in all cases, it can significantly affect, in both negative and positive ways, the competitiveness of an organization. In the present study, in addition to the investigation of concept and forms of organizational forgetting, we studied the relationship between purposeful organizational forgetting and charismatic leadership and determined of the amount of organizational forgetting, due to strategic importance of purposeful organizational forgetting. The data necessary for this study were through questionnaires that were given to 165 top and middle managers and supervisors in the supply chain of Iran automobile industry. Correlation analysis of data by chi-square test showed that there is a significant relationship between every dimensions of purposeful forgetting (new and established knowledge) and charismatic leadership.

Abstract Vajhollah Ghorbanizadeh ,Asgar Moshabbaki2 1. Ph.D. Student of Management, Tarbiat Modares University, Tehran, Iran 2. Associate Professor of Management,Tarbiat Modares University, Tehran, Iran Received:4/17/2005 Accept:1/7/2006 Abstract Creating and protecting competitive advantage by organizations in the 21st century, requires identifying affective environmental changes on organizations, agility and adoption with those changes and increasing capability for answering the various needs of customers. Only learning organizations have these properties. For being learning, organizations apply a process that includes four sub processes including: 1) identifying and creating information, 2) interpreting and transforming information, 3) applying information at work/ creating knowledge, and 4)institutionalizing of knowledge. Applying these processes requires organizational fitness and specific characteristics of leadership, manpower, organizational design, organizational culture, mission and strategies. These characteristics facilitate learning and becoming learning organization. Innovative aspect of this research is that it provides a model that identifies learning levels of the automobile pieces manufacturing firms based on learning process and learning organization characteristics. The obtained results indicated that learning level differs from one firm to another and we can divide all organizations to three levels: 1) data oriented, 2) information oriented and 3) knowledge oriented with respect to their focus on data, information and knowledge. Considering how much learning process is applied and how much characteristics of learning organizations are obtained, each organization lays on one of the mentioned category levels.
