Forbes magazine contributor, Adam Hartung, also alluded that the bribery scandal was a reflection of Walmart's "serious management and strategy troubles," stating, "candals are now commonplace ... ach scandal points out that Walmart's strategy is harder to navigate and is running into big problems.
