Improving Manufacturing Performance by Standardization of Interprocess Communication

A number of environmental forces such as increasing value chain network complexity, decreasing product life-cycle cost, and time-to-market requirements or increasing product complexity act upon manufacturing organizations, enhancing the acute need for organizational routines that foster efficient and effective communication between processes. Such organizational routines erode quickly in the absence of common standards for knowledge sharing, that is why successful manufacturing systems benefit from interprocess standardization. The purpose of this paper is to offer a standardization model of interprocess communication that increases manufacturing operational performance (MOP). First, we propose a novel holistic model that makes standardized interprocess communication possible in manufacturing organizations. Second, we propose a model for quantifying the implications of standardizing interprocess communication upon MOP. Finally, as a matter of application, we show the results of its successful implementation in one Japanese manufacturing organization.

Complexity as contingency in sales and operations planning

Purpose – 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.
