This study aims to create and develop an approach for the design and gradual delivery of the product in the shortest time and through the balance of the elements of technological readiness, the need statement document, and the characteristics of the product in large and complex air systems.

Design/methodology/approach:

 In this study, the balancing process has been carried out using three stages of the Quality Function Deployment (QFD). In the first stage, product specifications have been prioritized using customer needs. In the second stage, product specifications have been prioritized based on the specifications of the first stage. In the third stage, the required technologies have been prioritized using the specifications of the product in the second stage. To conduct the research, industry experts who were in the unit related to the desired product provided the necessary data. Out of the 10 experts in that unit, seven have collaborated in the design and implementation of the model and three have approved the model. Finally, the discussion model was approved by the company's high committee.

After extracting the priorities of technologies, the final meeting of the QFD group was held with the presence of expert designers and the operator's representative. In this meeting, the process of using QFD and the obtained results were discussed. Then, using the scores obtained for the technologies (priority value) level of technological readiness for each of the product technologies and the approaches of designing, producing and delivering the primary, intermediate and final products were determined. The results of product prioritization based on technology development were also approved by the high committee.

Research limitations/implications:

 In this research, the balance of technological readiness, a document of requirement statement, and product characteristics in the design management of macro systems of defence air base products were analyzed by QFD. There was a need to check if there were other tools for balancing. Also, the scope of this study was limited to product design, and it is necessary to extend the balance to the entire life cycle of the product. In this research, the researchers faced with challenges due to the lack of familiarity with the elites or complete and sufficient research and training of the elites and managers of the country's research and defence industries. Also, the lack of managerial approaches to system and standard design and the integration of the approaches communicated by the regulatory and standardization centres of the country on the system design of large and complex products were the other limitations of this research.

Practical implications: 

The model proposed in this research made it possible to produce large and complex products in the aviation industry due to the existence of restrictions. On the other hand, the gradual design, production, and delivery of big products made the products suitable for the user's scene to be designed and produced first. While maintaining the quality of the product, the time to obtain the products should also be reduced.Social implications: Acquiring large and complex products in the country will accelerate the country's development.

Originality/value:

 The design and production of large and complex products based on technology development with a gradual product delivery approach using QFD is one of the innovations of this research. The application of the proposed approach will resolve some of the problems related to the design of large products in different areas.

Cost, quality and design time of macro integrated products are important and necessary factors in design management. The aim of the current research is to provide an integration model for technological readiness, requirements statement document and also description of product features in the management of macro system design in domestic air base products. In particular, the research intends to reduce the time required for the final delivery of the product by identifying and prioritizing the real and prospective needs of customers/users, while applying gradual changes and evolutionary measures. The research method is survey-descriptive in terms of execution. In fact, the approach of data survey and analysis is carried out quantitatively using exploratory and confirmatory factor analysis. The results obtained from the significant factor loading coefficient and path coefficients as well as the test results of the research variables show the following. The significant coefficient of six paths - among the visible and hidden variables in addition to the components determined in the research conceptual model - is higher than 1.96 at the 95% reliability level. These numerical results confirm the research hypothesis and validity of the model fit.

The war game is one of the most common methods of military futurology or, to put it better, military future creation. The intended research is applied in terms of purpose and descriptive-survey research in terms of procedure. This research is in the field of decision-making and the use of AHP method has been used to prioritize the strategies that determine the battle scene. The statistical population of the research was 60 people and the statistical sample of the research was 20 experts in the field of air defense. In this research, strategies have been prioritized in four steps: 1- Enemy operational level 2- Insider operation level 3- Tactical level confrontation 4- Tactical level war game. Also, ADSS and STK software were used and the instrument used was a researcher-made questionnaire, and to check the validity of the instrument, the content validity of the instrument was approved by experts in the field of air defense, and Cronbach's alpha test was used for the reliability of the research instrument. A number of 0.83 was obtained. The result of this applied research is the prioritization of the strategies that determine the battle scene with the war game approach in the command and control system in the field of air defense, which provides the possibility for the organization to take a purposeful step in the future and not be captured by future incidents.
