1) Walmart struggled when entering the German market in the late 1990s due to stringent regulations around store size and development. German competitors like Metro and Aldi were already well-established with loyal customer bases. 2) Porter's 5 forces analysis showed high bargaining power for suppliers and customers in Germany. Competition was also intense from dominant German retailers. 3) While Walmart's entry provided some benefits like jobs, it made mistakes by imposing an American approach and not adapting to the local market. To succeed, Walmart needs to create goodwill and develop European suppliers.
