External wine education and certification for restaurant service staff: a mixed-methods evaluation of training effectiveness

Abstract

Purpose – The purpose of this mixed-methods explanatory sequential study was to assess the effects of an external wine education and certification program on trainee reactions, learning, transfer and financial results. Design/methodology/approach – The quantitative phase was a mixed experimental design in which the training intervention was between-subjects and time was within-subjects. The sample comprises 91 employees (NTraining = 43; NControl = 48) from 12 units of a fine dining restaurant group. The qualitative phase, comprised of semi-structured interviews with training group participants (N = 12), was implemented after the experiment. Findings – Training group participants reported high scores for attitude toward training content, instructional satisfaction and transfer motivation. Financial metrics, tracked up to 60 days post-training, demonstrated the wine education program was effective in increasing wine knowledge but not wine sales. Four themes emerged from the qualitative data: sense of accomplishment, enhanced guest interaction, tips and gratuities and defeat. Integrated findings revealed increased wine knowledge led to personal financial impact (increased tips) rather than organizational impact. Originality/value – This research builds on existing training literature and human capital theory by examining external training programs. Further, the use of a mixed-methods design and integration of the quantitative and qualitative findings offers a previously unidentified explanation for why wine training, although effective in facilitating positive reactions and learning, fails to result in transfer behaviors which generate increased wine sales.
