Identification of factors affecting the time performance of product development in terms of the three ramifications

One of the key factors in the development of new products, especially electronic and military products is the development time of these products or simply the time between the idea and final product. In this research, authors have tried to explore the subject from different dimensions and concurrently with studying the results of several research projects in the context of improving the time performance in military industries, suggest their practical results on the basis of their industrial, consultancy and academic experiences. offering a model and comprehensive classification that fulfill the most important effective factors on time performance of product development projects and yet consider the challenges of an active industrial sector in Iran in a common language with industrialists, can guide managers and policy makers of the product and technology development field in the context of strategy formulation and planning for decreasing development time of products. the aim of this research was to achieve such a comprehensive classification and therefore by performing library studies, holding experts panel and finally using thematic analysis, the set of effective factors on product development time was subdivided to three ramifications (contextual, behavioral and structural), nine themes(far environmental factors, nearby environmental factors, human resources, management and leadership, resource management, enterprise architecture, strategy, cooperation and project) and more than 23 sub themes. Finally, to sum up, some managerial implications and limitations of this study and conclusions will be discussed.
