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 Thule, in this view, were simply whale hunters who followed the migration of their prey in a warming climate. Environmental conditions, not a sophisticated culture, was the key explanation for their success. Emphasizing climate as the cause of migration and social success reduced the achievements of the Thule, essentially, to those of their prey. However, twenty-first century evidence is changing this account of Thule migration.
