8. IETM AUTHORING GUIDELINES.
8.1 . Authoring style guidelines for IETMs. To ensure clarity
within IETM data, the following principles should be followed in
authoring technical information.
a. Essential information in narrative text should:
(1) Describe the system, components, etc., identifying
special or outstanding features.
(2) Describe what functions are performed, including
inputs, outputs, interface with other systems, etc.;
emphasize end results.
(3) Describe how the functions are performed, including
associated principles of operation.
(4) Describe at what point in an overall system process
the function is performed.
(5) Describe the location of the component or part.
b. When procedural text is combined with graphics, the
following rules should be used to abbreviate, so long as
the meaning is not altered or obscured.
(1) Eliminate articles.
(2) Begin sentences with transitive verbs (action verbs).
(3) Use the imperative mood whenever appropriate. The
only time subjects should be implied is when they are
unknown and the passive voice is being used or when the
imperative mood is being used to give an instruction,
order, or command, in which case the subject should
always be omitted (i.e., implied).
c. When it is necessary to indicate time, begin sentences with
“when” clauses. Example: “When power supply voltage
stabilizes...”
