There are two main types of organizational structures: centralized and decentralized. In a centralized structure, decision-making power is concentrated in one manager, typically the business owner, allowing for efficient decision-making but potentially slowing operations. Decentralized structures distribute decision-making across multiple individuals with specialized knowledge, utilizing diverse perspectives but making consensus more difficult. A participative structure combines elements of centralized and decentralized approaches. When choosing a structure, businesses should consider their size, with smaller organizations often finding centralized works best and larger ones leaning toward decentralized.
