How would you describe Nokia’s competitive advantage when it was strong in the mobile phone market? Today?

Nokia was once the world’s largest maker of phones. These days, smartphone buying customers hardly recognize Nokia as a maker of such. Given its absence in the past decade from one of the hottest product categories, one might think that Nokia went the way of once-mighty brands like Kodak or Sears. But today, Nokia is actually thriving—not as a manufacturer of phones, but as a supplier of network infrastructure for industrial telecommunications service providers. How did Nokia escape extinction and rise to market leadership in a different industry? The answer lies in a long and difficult process of transformation and reinvention.
