Document intent

A documented strategy provides direction and reference points, and reminds you what you're doing and why. This helps ensure consistency in decision-making and action.

A business plan specifies goals and resources, and clarifies reasoning. It's like  a roadmap for growth, and can attract interest from investors and other stakeholders. 

Policy documents make explicit how you do things in your organization. They formalize your principles, and guide how decisions should be made and action taken. They help ensure consistency, transparency, compliance, efficiency and accountability. 

Procedure documentation provides the specifics of how to implement policy, detailing the steps required to do what needs to be done.
