Technology transfer managers or researchers have formed some models in their perspectives to cope with the challenges they have faced before. There are many methods of separating technology transfer models, however, we preferred to separate technology transfer models into two main categories. They are qualitative models and quantitative models.3.4.1. Qualitative models Jagoda (2007) points out that qualitative models involve non-numerical psychological activities in technology transfer that have a direct effect on the success of the company. There are many qualitative models such as;• The Bar –Zakay model (1971);• The Behrman and Wallender model (1976)• Dahlman and Westphal model (1981)• Schlie, Radnor and Wad model (1987)• Chantramonklasri model (1990) The common thread of all these qualitative models is that they divide the technology transfer process into several categories themselves and try to cope with the transfer process by ignoring analytical or mathematical data. Furthermore, these models have some weaknesses. The Bar Zakay model (1971) provides four phases of the technology transfer model. Furthermore, it has limited relevance to current conditions. The Behrman and Wallender (1976) model consists of seven categories. The weakness of the Behrman and Wallender model is that the contribution of the transferor is slightly low and the transferee is the basis. The Dahlman and Westphal (1981) model has nine stages as in the technology transfer model. This model is the model developed as The Behrman and Wallender. The main weakness of this model is that the transferee requires high-level engineering skills. The Schlie, Radnor and Wad model (1987...... half of the article ...... geology varies with respect to cultural differences, work habits and norms (Slowikowski and Jarratt, 1997). • Company factors Product characteristics and business decisions include business factors and the main problem that the factor faces is conflicts between shareholders and managers • Human factors Human factors influence the transformation process in terms of employees and their effectiveness rates. their seminars or training courses. (Mitala and Pennathurb, 2004) • Geographical factors Geographical factors are another crucial point of the technology transfer process, as they directly influence the technology transfer and adaptability problems is considered a technical problem and can influence on the use of equipment capacity in terms of temperature, climate problems, air conditions, humidity of voice channels.
