Rexair manufactures “Rainbow Cleaning System“ which is marketed both in the USA and internationally in 33 countries with the sane program. Here, Rainbow represents the product transfer which is totally Imported from the US and the Total Program represents the transfer of managerial know-how by the Verpa Corp.. To understand the present situation of the Verpa Corp. in the market aid to analyze the performance of the current marketing strategy, two different questionnaires were administered to dealers and customers. Besides, observations and interviews with managers, dealers and customers were also performed and used both in the design of the questionnaires. Managers and dealers were asked basically about the organization structure, weaknesses and strengths of the currently applied Total Program, and their problems related to the company and the job. On the other hand, customers were wanted to answer the questions related to the product, dealers’ performance and also their complaints in general. The first questionnaire was distributed to 14 dealers in the company and the second one was given to 30 customers. Therefore, the company was evaluated by both parties. According to the questionnaire results, dealers were grouped as the ones who worked less than 6 months and the dealers who worked more than 6 months. Customers were grouped as A, В and C according to their socio-economic status (SES). To find out the significant relation in the answers of these groups t-test was applied. However, no significant difference were found in the answers of the groups in both questionnaires.
