- Complexity as contingency in sales and operations planningPublication . Thomé, António Márcio Tavares; Sousa, Rui Soucasaux; Carmo, Luiz Felipe Roris Rodriguez Scavarda doPurpose – The purpose of this paper is to test whether complexity interacts with Sales and Operations Planning (S&OP) practices by positively moderating the impact of S&OP practices on manufacturing operational performance dimensions of quality, flexibility and delivery. Design/methodology/approach – Three hypotheses are developed on the relationships between S&OP practices, task complexity and process complexity and manufacturing operational performance. Scales are validated with structural equation modelling. The hypotheses are tested through a hierarchical regression analysis using data from a sample of 725 manufacturing plants from 21 countries. Findings – S&OP practices of organizational management, technological integration, measurement systems and integration of plans impact positively on manufacturing operational dimensions of quality, delivery and flexibility. Process complexity moderates the effect of S&OP practices, amplifying its impact upon all three performance dimensions. Product complexity moderates the effect on quality, but not on delivery and flexibility. Practical implications – S&OP practices of organizational and technological coordination of manufacturing and new product design; information technology to measure information sharing and planning; dedicated information systems do impact upon manufacturing operational performance. Results are amplified by process complexity. The more complex are the manufacturing processes the larger the gains of S&OP. Originality/value – This research applies contingency theory to S&OP and empirically demonstrates its impact on manufacturing operational performance and the moderator role of complexity.

- The impact of sales and operations planning practices on manufacturing operational performancePublication . Thoméa, Antônio Márcio Tavares; Sousa, Rui Soucasaux; Carmo, Luiz Felipe Roris Rodriguez Scavarda doThere is a lack of rigorous empirical studies directly examining the impact of sales and operations planning (S&OP) practices on manufacturing operational performance. This paper aims to fill this gap by analysing a sample of 725 manufacturers from 34 countries. Hypotheses relate internal S&OP, integration with suppliers (IS) and integration with customers with manufacturing operational performance (delivery, quality and flexibility). The constructs were validated with structural equation modelling and the hypotheses were tested using multiple stepwise regression. Our findings showed a positive and moderate-to-large effect of internal S&OP on manufacturing performance, controlling for firm size, country economic development and market dynamics. There was no significant impact of supply chain integration on manufacturing performance. However, we found that IS positively moderated the relationship between internal S&OP and performance, suggesting that firms with mature IS amplify the effect of internal S&OP on performance. The study is among the first to empirically and rigorously establish the impacts of S&OP practices on manufacturing performance, using a large sample of manufacturers spanning different countries, markets and firm sizes. Results show that S&OP practices have a broad impact across several performance dimensions and are a powerful lever for generating manufacturing performance.
