Michael Porter and Sustainable Competitive Advantage Just because a company is the market leader now, doesn't mean it will be forever. A company must create clear goals, strategies, and operations to build sustainable competitive advantage.
from Wikipedia Website. Thule as Tile on the Carta Marina by Olaus Magnus. Thule (also Thula, Thyle, Thile, Thila, Tile, Tila, Tilla, Tyle, or Tylenbeing Î¸Î¿ÏÎ»Î· in Greek) is in classic sources a place, usually an island. Ancient European descriptions and maps locate it either in the far north, often northern Britain or Scandinavia, or in the west and north, often Iceland or Greenland.
The term Thule migration became commonly used in disÂ­ cussions of the appearance of Thule culture in the central and Eastern Arctic; less commonly used was the term Thule expansion, also implying a relatively large-scale movement of people.
