Which concept emphasizes that an internal system must match the complexity of its external environment?

The concept of Requisite Variety is significant in understanding how organizations operate within complex environments. This principle suggests that for an organization to effectively manage and respond to the challenges posed by its external environment, its internal systems and processes must possess a variety of responses and capabilities that match that complexity.

In essence, if an organization is faced with a diverse set of challenges from its environment, it must have equally diverse strategies and structures internally to address these challenges effectively. The idea is rooted in the work of cybernetics and systems theory, particularly in the context of understanding how organizations function and adapt in dynamic settings.

By employing Requisite Variety, organizations can better navigate changes, uncertainties, and complexities in the external environment, leading to improved resilience and performance. This concept underlines the importance of alignment between internal capabilities and external demands, reinforcing the necessity for organizations to evolve over time alongside their surroundings.

Other concepts, while related to organizational functioning, do not specifically emphasize this alignment feature to the same extent. Systemic complexity refers broadly to the intricate and interconnected nature of systems without focusing on the specific match required. Environmental adaptability suggests the ability to change in response to external conditions, but it does not explicitly mention the need for internal complexity to match external complexity.
