Acer went through several changes in course over the years in response to shifting market conditions. In the late 1990s, Acer lost US market share to competitors like Dell and implemented a "21 and 21" strategy to decentralize operations. In the early 2000s, Acer again restructured by splitting into different brands and focusing on more profitable regions and products, including introducing early tablet PCs. Acer's founder emphasized empowered and decentralized decision making. Acer continues reshaping strategies to adapt to a changing global business environment while gaining a strong foothold in computers and exploring new product categories.
