Requirements for diagrams and flowcharts
1) Passive voice
As mentioned earlier, using passive voice is a critical feature in this type of
writing. The main reason for this is that in describing diagrams, the “subject”
is not focused; instead, “the product” is highlighted. Consequently, there is
little usage of “active voice” in writing diagrams in general.
As a quick review, the passive voice is formed by removing the “subject”
from the active voice, adding a “to be” verb, and changing the sentence’s
main verb to the past participle form. Revising the most common “verbs” and
their “past participle” forms could be an asset in describing diagrams.
For example
They
make
cars in factories. (
active voice
; there is a subject, “they,”
who do something.)
Cars are made
 
in factories. (
passive voice
, there is
no subject; the object or the agent, “cars” has replaced it; the sentence
shows that something is done rather than who does it; “to be” verb,
“are” and the past participle, “made” are put in the sentence to form
the passive structure.)
