Situation I: (Answer(15, 016 & (17 on the base of following data) Samsung launched the Galaxy Note 7 to record preorders and sales in August, but the rosy start soon turned sour. Samsung had to initiate a recall in September of the first version of the Note 7 due to faulty batteries that overheated and exploded. By October it had to recall over 2 million devices and discontinue the product. It's estimated that the recall will cost Samsung $5.3 billion. It turns out that Samsung engineers knew of this issue a year before the product was launched, but CEO of Samsung Inc., liked the design and chose to go ahead with it. The controversy even caught the ear of a U.S. senator, who urged Jobs to fix the problem at no cost to consumers. Contrary to typical industry practice, AT&T, the exclusive service provider for Samsung's phones, was allowed to test only a disguised phone for a very limited time without charging it, so the problem was not discovered during testing. So Samsung decides to recall the product, which was never easy, and yielding returns of more than 30 percent is extremely challenging. 15. Should Samsung have released the note 7 when engineers were aware of the battery problem? Discuss the benefits of further testing before launching the product. 16. Did Samsung handle the situation effectively? Did Samsung's Phone lose brand equity from this controversy? 17. What do you think about "Team-based new-product development" for Samsung
