A company that comes to mind when I hear industry attractiveness is Apple. They recognized the potential of the consumer electronics market in the early $2000$s and identified attractive segments such as smartphones, music players, and personal computers. When they entered this segment, they planned on capitalizing on their growth by consumer demand and technological advancements. For example, we now see that a smartphone has musical capabilities integrated into it rather than being a separate device. When assessing a companys unique resources, how do you differentiate between valuable, rare, and hard$-$to$-$imitate factors?
