What is a short sentence or paragraph that describes an organization’s essential tasks and purpose called?

A mission statement succinctly articulates an organization's essential tasks and purpose. It serves as a foundational element that conveys the organization's core objectives, guiding principles, and primary functions. This clear and concise declaration helps to inform both internal stakeholders and external audiences about the organization's goals and intentions. In contrast, a vision statement is more focused on the long-term aspirations and desired future state of the organization, while a strategic plan outlines the broader initiatives and strategies necessary to achieve the organization’s mission and vision over a specific period. An operational directive, on the other hand, typically deals with specific actions or orders related to processes or tasks, rather than defining the overarching mission or purpose of the organization.
