Abstract
Purpose The aim of this research was to consider whether focus groups have justifiably become a more frequently used qualitative market research technique because of a superior research outcome. Although focus groups have extrinsic advantages such as speed and cost, there is evidence that individual depth interviews have intrinsic advantages relating to the quality of the research outcome. Design/methodology/approach A parallel research study was undertaken examining a single business issue using both focus groups and individual interviews. Results of both processes were analysed for relevance to the business issue. Follow up individual interviews with participants of the focus groups were undertaken to assess the validity of the data collected, and to investigate the nature of the processes in the groups. Findings Group processes appear to have had considerable influence on the consensus view expressed in focus groups, which may not be representative of respondents' individual views. Both the groups and the interviews identified the principle issues relating to buyer motivations and processes, target markets and branding. The groups were unable to match the depth and detail generated by individual interviews and to uncover subtleties in attitudes. The interviews offered less breadth of data and contextual information. Practical implications Whilst groups may be less expensive and faster in data collection, individual interviews demonstrated a superior ability to inform marketing strategy by uncovering important underlying issues. Originality/value The findings indicate that groups do not justify their predominance as a market research method in preference to interviews on the grounds of quality of outcomes alone.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
