A model is a simplified representation or description of a concept, system, process, or behavior used to help understand, explain, or predict how something works. Models serve as references or guides, whether they demonstrate how to behave (like a role model), how to perform a task, or what outcomes to expect.
They can take many forms, including physical replicas, diagrams, theoretical frameworks, or behavioral examples. By providing clarity and structure, models help individuals and organizations make informed decisions, learn new skills, or anticipate results in complex situations.
