We know that Sales and Operations Planning (S&OP) is a cross-functional process, bringing a company's demand- and supply-side people together to reach consensus on the demand forecasts and operating assumptions. The participants typically engage in a series of meetings across each month, and the process outcome is determined by how effectively the individuals collaborate within the team. As Scott Ambrose writes here, principles of team effectiveness have been widely studied, but not applied previously to S&OP. Scott's article examines how recognition and implementation of these principles can improve S&OP collaboration and performance.
