I have recently only been exposed to the WalMart phenomenon - I know, what rock have I been under - so I've been looking them up all over. This is one of the 4 books I have read and it gave me a good understanding of the strategies involved in running the behemoth.I have been in awe of every single strategy implemented and of course this is no surprise. They have executed every aspect of their business flawlessly.Michael goes through Walmart's POCKETS:Pricing StrategyOperational StrategyCultural StrategyKey Item/ Product StrategyExpense Control StrategyTalent StrategyService StrategyHe discusses each strategy with relative depth and explains Walmart's competivite advantage in its execution. Overall a very informative book, I definitely recommend it for people going against Walmart or anyone trying to understand Walmart's success.
