The knowledge retention management problems of the Lithuanian armed forces are classified into: human, organizational, functional, technological and technical. In order to solve the problematics of such type, the identification of the factors, that provides the premises for the complex assessment of the knowledge retention process, becomes an important factor. The purpose of the article is to identify the factors that are significant for the evaluation of the knowledge retention process effectiveness of the Lithuanian armed forces.

Due to a dynamic environment, human resource competency evaluation and factors influencing its outcome are in constant change. Evaluation of human resource competency and factors influencing its quality are widely discussed subjects in scientific literature with ample controversial viewpoints. Various definitions, points of view and models makes it difficult to choose the best option when evaluating human resource competency and may be the source of the following problem: how to know that the chosen competency evaluation method will convey reality and deliver objective results that could be used as a basis for human resource development related decision making in the future. This study analyses different scientific views on the human resource competency evaluation process. The purpose of this study is to develop a conceptual model for competency evaluation of professional military service in the Lithuanian armed forces that would allow for human resource potential evaluation and form a basis in human resource development related decision making processes in organization. Multiple criteria assessment methods were used for identification and evaluation of factors influencing human resource competency. As a result of conducted research, authors developed the conceptual complex model for competency assessment of professional military service in the Lithuanian armed forces, which enables objective identification of human resource competency influencing factors and forms the foundation for decisions related with development of human resources in organization.
