Step 1: Understanding the Concept:
An organization is defined as a structured social unit of people who are structured and managed to meet a need or to pursue collective goals.
Step 2: Detailed Explanation:

These individuals (persons) bring distinct skills, coordinate their efforts, and work in a structured hierarchy to achieve common objectives.

Therefore, individual persons coming together under a common goal form the organization.
Step 3: Final Answer:
