D Question 3 1 pts Samsung Electronics has three business segments: consumer electronics (CE), information technology and mobile communications (IM), and device solutions (DS). In 2015, the CE IM, and DS segments accounted for 25%, 48%, 27% of total revenues, respectively. Consumer electronics and mobile communications divisions share a number of intangible capabilities (e.g, know-how and expertise) in product design and development. It can be concluded that Samsung Electronics is pursuing ain) strategy. O dominant business O single business O...
