This is the 1953rd most frequent Russian word.
сделано
"Made" or "done."
In this sentence, 'сделано' is used in the past passive voice to indicate that something (an action or task) has been completed, emphasizing the result of the action.
Это сделано для вашего удобства.
This is done for your convenience.
Here, 'сделан' (discussed regarding gender agreement) is part of a passive construction describing the repair as a completed action, with an emphasis on the manner (performed quickly).

'Сделан' in this case refers to the first step as being accomplished, highlighting its completion.
