North Holland Elsevier. A survey involves administering standard questionnaires to a large sample population.
Surveys can help determine customer preferences, work practice and attitudes.
Open surveys are applicable in the same kinds of situations as semi-structured interviews, closed surveys as structured interviews. Interviews are preferable in situations where there is a lot of person-power available for requirements elicitation and the user group is easily accessible. Surveys should be used, by preference, in situations where the user group is spread out geographically or where person-effort is small. Benefits Quick and relatively inexpensive to administer. Results can be subjected to statistical analysis Limitations Questionnaire design is not straightforward.
