Which fact-finding technique can be used to obtain information about a wide-range of topics, including workloads, reports received, job duties, difficulties, and opinions of how the job could be performed more efficiently?

The correct answer is Questionnaries.

Explanation:

The questionnaires are a series of ordered questions, which seek to obtain information from the person who answers them, to serve the questioner or both parties.

The questionnaires are often used as an evaluation technique, or as a research guide, or also to carry out surveys, where questions are asked about certain “questions” that are to be found. They are widely used in education, in Psychology, in Sociology and in market studies.

The questions must be brief, open (free to express) closed (you must choose between preset alternatives) or by combining both; precise, numbered, unambiguous, unconditional, and written in terms of language and complexity, according to age and studies or knowledge that is supposed to have the questioned.
