Hello everybody, I�m not sure that this is the right page to ask you some questions but I don�t know where to go. I�m a student of a University in Switzerland and I�m writing my thesis about the elevator industry and the comparison between corporate strategies of Schindler and Otis. I have some problems and maybe someone of you can help me. I don�t know how functions the marketing of an elevator society, it doesn�t do advertisements on television or on the newspaper, so how can a firm publicizes the elevators? People buy Otis�s elevators or Schindler�s elevators only for the brand? What motivates people to buy an elevator rather than another one? Another question that I have is about the provision of Otis, I know that Schindler uses SupplyOn with suppliers and many subsidiaries in the whole Europe buy from suppliers in a large amount reducing costs, and what about Otis? I can�t find any information about provisions. The last question is: why otis is the number 1 for elevator manufacturer and schindler occupies the second position? what is the main difference?
I would be very grateful if you could attend to this matter in order to help me for my thesis.

Thank you!
