This paper explores, based on literature review and case analysis, the key success factors in the formation of alliances. Its contribution rest on the identification of practical insights, namely: (i) formal processes of alliance management; (ii) formal mechanisms of alliance learning; (iii) teams responsible for the life cycle of the alliance (beginning to end); and (iv) the existence of an empowered alliance office. The study also finds that supporting suppliers in the alliances can be a cost-effective way to improve internal performance.
