The basic rule is to define functions using two words, a verb and a noun.
The resultant definition should be such that it is not restrictive in that it
defines a method for performance. An abstract definition will offer an
opportunity for creative questions that may produce a number of alter-
natives. For example, using “file papers” as the definition of a function
may limit our thought on using papers, folders, and cabinets. By using the
more generic definition of “store information,” we can open our thoughts
to other ideas such as computers, and CDs to read, retrieve and catalog
information.

It is also important that the function be measurable in some unit term such
as weight, cost, volume, time, or space. In some cases, the measure may be
satisfaction, desire, or some other abstract measure that will require more
