Nowadays, more productivity is seen as an intellectual standpoint, and a thinking mode for the continuation of progress, and in its depth of meaning, it is an attitude for rationalizing activities. The greatest evidence of the modern age is change. The world around us is changing on a constant base. The purpose of the study was to determine the dynamics of human resource productivity and scenario developing for the organization in the coming years, considering the factors currently being used for it. The problems in this regard for the organization are numerous, such as the unknown nature of the exact effect of each factor on the productivity of the human resource of the organization. The methodology of system dynamics is based on three various disciplines: traditional social systems management, feedback theory or cybernetics and computer simulation. Vensim software is used in this method.

Using the flow diagram, it is understood that if the workforce indices - experience, training, job security and job satisfaction - increase, they will increase productivity. Moreover, the omission of the delay in paying salary will have the same effect. One of the objectives of dynamic system modeling is to study the various potential policies to improve system performance. Making these changes has brought about 56% increases in the organization's workforce productivity.
