MGM Grand Hotel in Las Vegas has achieved success through innovative management techniques under CEO Larry Woolf. It operates on a hierarchical structure with senior managers responsible for overall operations and lower managers handling various levels. While an autocratic management style is common in Las Vegas casinos, MGM also employs elements of Theory Y such as cross-training managers to gain employee insights and an integrated benefits system. Additionally, MGM's quality assurance program focuses on participative management and empowering lower-level employees to solve problems and make decisions quickly. These techniques have provided MGM Grand with the structure needed to enjoy ongoing success.
