Which of the following best describes a plan for inmate commissaries?

A written plan approved by authorities is essential for establishing an inmate commissary system because it provides a structured framework to ensure that all operations comply with regulations and policies governing the detention facility. This plan outlines how the commissary will function, detailing aspects such as the types of items available for purchase, pricing, inventory management, and procedures for handling funds.

Such an approved written plan conveys the facility's commitment to maintaining order and ensuring that inmate needs are met in a manner that aligns with safety and security protocols. It acts as an official document that can be referenced for policy adherence and operational consistency.

In contrast, a comprehensive resource guide, while informative, does not have the same level of authority or requirement for implementation. A recommendation report serves as an advisory document that may provide suggestions but lacks the formal approval necessary for implementation. A mandatory checklist may be useful for procedural tasks but does not encompass the broader, strategic planning required for commissary management.
