Which aspect should not apply to the development of an effective emergency disaster plan?

An effective emergency disaster plan is most effective when it incorporates broad involvement from various stakeholders. This comprehensive approach ensures that multiple perspectives and expertise are included in the planning process, leading to a more robust and well-rounded plan. By limiting participation to a minimum number of people, key insights, skills, and resources may be overlooked, which could hinder the plan's effectiveness during an actual emergency.

In addition, a well-developed emergency disaster plan must be written down to provide clear guidance, ensuring that all individuals involved understand their roles and responsibilities. This written plan must also contain an inventory of available resources, as knowing what is accessible is crucial for effective response and recovery efforts. Lastly, including preventative measures in the plan helps mitigate potential risks and outlines strategies to prevent incidents from escalating. Thus, the emphasis should always be on wide collaboration and comprehensive content in the planning process.
