What term is used to communicate a recommended practice rather than a mandatory one?

The term "should" is used to communicate a recommended practice rather than a mandatory one. This terminology suggests that while the action is advisable and encouraged, it is not an absolute requirement. In the context of industry standards and guidelines, the use of "should" indicates flexibility and allows for some discretion based on the situation or specific conditions.

In contrast, terms like "shall" and "must" denote absolute obligations that must be followed without exception. "Will" is often used to express a future intention or certainty rather than a recommendation. Thus, "should" is the appropriate choice for illustrating practices that are advisable but not compulsory.
