Employees, as the most important assets of an organization, acquire a great deal of experience, skills and knowledge throughout the time period they work for the organization. If their skills and technical knowledge are not documented properly, these will be lost once the employees leave the organization. Therefore, documentation is necessary for preserving this invaluable knowledge, avoiding duplication and preventing repeated mistakes that occurred in the past and, providing the junior staff with experiences gained by their predecessors. Thus, this research aims to elaborate on the role of organizational knowledge management (KM) as an essential tool for turning tacit knowledge into explicit knowledge and sharing the gained experiences with others.

This research is developmental applied research with qualitative approach and it was conducted using thematic analysis method. This method includes a semi-structured interview with 18 researchers conducting research projects at the Satellite Research Institute under the supervision of the Iran Space Agency.

The projects contain knowledge that is a combination of “know why”, “know what”, “know who” and “know how”. A large amount of this knowledge is, indeed, the tacit knowledge. Most of this tacit knowledge is not reflected in the project documents. Generally, the documents contain results only and they do not include experience, technical details, methodology, analysis and mistakes that were made during research activities. Documentation challenges fall into three major types: technical, human resources and administrative.

Considering the necessity of documentation within the knowledge transfer process and its important role in KM; and, with respect to the lack of technical knowledge and experience transfer observed in the documents of Satellite Research Institute, this research proposes some steps that need to be taken to turn the knowledge sharing into an organizational culture.

This paper aims to provide knowledge about methods used to evaluate the accessibility of Iranian web sites through a real research environment.

The main theoretical base of this article is that almost all research conducted to evaluate the accessibility of web sites has used only one of three methods (namely manual, automatic and users' experiences). However, it seems that using a combination of these three methods is actually necessary. Consequently, taking a critical approach this article examines 18 Iranian ministerial web sites using the three methods.

Findings in both documents and evaluative studies show that each of the methods has deficits and it is necessary to employ a combination of the methods in order to conduct a reliable accessibility assessment. The different rankings of ministerial web sites in various evaluations have confirmed this view.

Identifying the advantages and disadvantages of the three methods and employing them in real research environments to assess the accessibility of ministerial web sites has been a useful exercise. The work can not only be a starting point for further discussions on the reliability of accessibility evaluation methods, but can also be applied to other types of web site.
