PurposeThe purpose of this case study is to develop a complete understanding of the sales and operations planning (S&OP) process implementation effort at ASTRO Inc. and to determine the influential factors that led to its success, the interrelationship between them, as well as the level of influence of each factor compared to their counterparts. As we trace the evolution of S&OP in the organizational context, the view that its implementation leads to a positive impact in changing the way companies do business is not in itself novel. To date, there is limited academic investigation on how and why the S&OP process implementation leads to a successful organizational transformation.Design/methodology/approachThe data used in this case study were collected through semi-structured interviews with selected employees and through documentary analyses based on the archives at ASTRO Inc., a large North American company, for the period from 2016 to 2018. The paper adopts a methodology based on a retrospective study and interviews.FindingsThe analysis shows that the S&OP process design and its implementation required efforts on many distinct but complementary fronts to be successful. However, the level of influence varies across the organizational enablers that contribute to this success. Its successful implementation is fundamentally dependent on the managers' ability to create mindset changes in the organizational culture, and to plan and coordinate the S&OP process deployment. The key enablers need to be skillfully combined, taking into account the contextual variables, namely, the company's internal context, the company's external context and the specific characteristics of the industry in which the company belongs.Originality/valueThe current study provides a better understanding of the implementation of the S&OP process and highlights the key enablers that led to its successful implementation. It provides practical managerial guidelines for designing, deploying and using an S&OP process in response to and in anticipation of customer demands, and competitive pressures.
