Olga Louisa Kastner derives success factors for pop-up stores from pop-up retail literature and empirical studies from related research fields, identifies dimensions of success, and develops a hierarchical model of success factors. She explores the consistency of the model through two case studies from the international clothing industry. This approach demonstrates the model's suitability for practical application and showcases its technological potential by providing brand managers with concrete recommendations for action in strategic planning, operational execution, and subsequent success evaluation.
