Final answer:
Organizational Alignment defines organizations with the best fit between their social system and their technical system, emphasizing the synchronization of various aspects of an organization to support its goals.
Step-by-step explanation:
The term that defines organizations with the best possible fit between their social system and their technical system is Organizational Alignment. This concept refers to the degree to which the various aspects of an organization, such as its structure, culture, and processes, are in sync with each other and support the achievement of its goals. Organizational culture plays a role here as it encompasses the values, beliefs, attitudes, and systems that influence employees' behavior. Organizational effectiveness might also be relevant as it measures how well an organization is achieving its objectives, but it does not focus on the fit between social and technical systems specifically. Organizational Development is a more broad term that involves the processes of analyzing and developing an organization's effectiveness.
