The Circular structure is a visual and conceptual shift from the pyramid. It places the leadership at the center of the organization, with the different departments radiating outward in concentric rings. This is designed to represent the idea that the core vision flows outward to support the staff, rather than "bossing" them from above.

The Functional structure is the most traditional model. It organizes the workforce into specific departments based on shared skills or roles—such as Marketing, Finance, HR, and Engineering. Each department operates as a specialized unit with its own leadership.

The Hierarchical structure is the classic pyramid model. It relies on a clear vertical chain of command, where every employee (except the CEO) reports to a single supervisor. Authority is centralized at the top and trickles down through various layers of middle management.

The Matrix structure is a grid-like model where employees have dual reporting relationships. Instead of just one manager, an employee might report to a functional manager (based on their skill) and a project manager (based on their current task), requiring high levels of cross-departmental communication.

The Team-Based or Agile structure replaces rigid hierarchies with small, self-sufficient "squads" or "cells." These teams are multidisciplinary and empowered to make their own decisions quickly, allowing the organization to pivot and respond to changes in real-time.

The Divisional structure breaks a large company into smaller, semi-autonomous "mini-companies" based on specific products, services, or geographic regions. Each division typically operates with its own functional resources (like its own dedicated sales or accounting team).

A Flat or Horizontal structure minimizes or completely eliminates the layers of middle management. It creates a direct link between the executive leadership and the frontline staff, encouraging employees to involve themselves in decision-making and self-management.

The Network or Virtual structure is a decentralized model where a core "hub" organization relies on a web of external partners, freelancers, and vendors to perform key functions. Rather than owning every department, the central company acts as the coordinator for a global network of talent.
