A guideline is a set of recommended practices or principles designed to help individuals or organizations make informed decisions. Guidelines are often created by experts in a specific field and serve as a framework for achieving desired outcomes. They can cover various topics, such as health, safety, and education, providing clear instructions to follow. Guidelines are not mandatory rules but rather suggestions that can be adapted to different situations. For example, the World Health Organization provides health guidelines to help countries manage public health issues. By following these guidelines, people can improve their understanding and implementation of best practices in their respective areas.
