A compartment word can be used in many ways. For example, it can be used to represent an area of interest, a work group, a department, a division, or a geographical area. A compartment word in a label helps identify files and the individuals that are cleared to access them. For example, a classification of NEED TO KNOW in a label can be restricted by the presence of one or more compartment words defined with department names, such as ENGINEERING or HUMAN RELATIONS or LEGAL. A file with NEED TO KNOW LEGAL would be available only to individuals who had NEED TO KNOW classification and the LEGAL compartment word in their clearances.
For another example, a government agency or an international corporation might create a compartment word for each country or continent: USA, Mexico, China, Japan, Africa. A large company might create a compartment for each division: SunSoft, SunFed, SMCC, SunConnect, JavaSoft.
