Which document outlines the rules for how a firm will be run?

The Articles of Association is the document that outlines the rules for how a firm will be run. It serves as an internal regulation for the company, detailing the governance structure, rights and responsibilities of shareholders, and the procedures for important company operations such as meetings and decision-making processes. This document is crucial for ensuring that everyone involved understands their roles and responsibilities, and it helps to provide a clear framework for managing the company effectively.

Other options, such as the Memorandum of Association, provide information about the company's formation and its relationship with the outside world, including its objectives and powers. While Company Bye-Laws may serve a similar purpose in specific types of organizations or jurisdictions, they typically do not have the same formal standing or recognition as the Articles of Association. The Business Plan focuses on the strategic direction and operational plans for the company, rather than the rules governing its internal management.
