Differences between push and pull manufacturing
Push Manufacturing: manufacturing activities are planned based on a market forecast rather than actual customer demand.
• Emphasis on central planning
• Little communication between various stakeholders
• Material flows through in batches following a prescribed route in the work order
• Rely on heuristics
• Service levels assured by increasing and decreasing finished goods in inventory levels
Pull Manufacturing: manufacturing plan is based on actual customer demand.
• Control of manufacturing execution is at working level, which leads to much communication
• Material flows through the factory based on visual queues triggered by customer "pull"
• Rely on hands-on management
• Service levels are assured by increasing or decreasing levels between workstations
