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 Greek explorer Pytheas is the first to have written of Thule, doing so in his now lost work, On the Ocean, after his travels between 330 and 320 BCE. Descriptions of some of his discoveries have survived in the works of later, often skeptical, authors.
