What describes the internal rules of an organization?

Bylaws are essential documents that outline the internal rules and regulations governing an organization. They provide a framework for how the organization operates, including the structure of its leadership, the processes for decision-making, and the roles and responsibilities of its members. Bylaws typically cover aspects such as meeting protocols, voting procedures, and membership requirements, ensuring that the organization functions smoothly and adheres to its stated goals.

In contrast, a charter serves as a foundational document that establishes the organization itself, often focusing on its purpose and authority rather than internal operational details. A policy manual outlines specific operational guidelines and procedures within an organization but may not encompass the broader governance framework provided by the bylaws. Meanwhile, a mission statement articulates the organization's core purpose and values without detailing the internal governance structure. This distinction highlights why bylaws are correctly identified as the document that describes the internal rules of an organization.
