This represents a quota sample, as the head of the research department is instructing the interviewers to interview a specific number of participants from each category (manufacturers and service providers), rather than randomly selecting participants or using a predetermined order for selection (systematic sample). It is also not an area sample or a multistage sample, as there is no mention of geographic or hierarchical sampling procedures.
