2. Manufacturing Planning Systems
• 1960s 1970s
– Continue to evolve
• 1990s – ERP
– Integrated systems
– Expensive
• MANY VARIANTS
• MPS specific systems can handle planning,
logistics functions
– Not integrated
– More affordable
3. GMRG Data
• Global Manufacturing Research Group
• Since 1985
– Four rounds to date
– Same survey applied to manufacturers in 17
countries
• Our dataset
– 964 responses
– 736 answered question concerning ERP system
used

10. Conclusions
• There are a variety of ways to get MPS
• Vendor systems better for strategic planning
– In-house systems not significantly inferior
11. MPS use by Function
• Manual systems or desktop used by those
without formal MPS
• Desktop systems used by all
• Custom software more common in in-house
systems
• Major vendor systems move away from
manual, custom software, desktop
12. Operations Benefits & Costs
• Major vendor systems provide more benefits
– But not significant except against None category
• Small systems have cost disadvantage
– Perceived overall costs of Major Vendor systems
rated as reducing cost
13. Data Quality
• Major Vendor Systems rated best
– Small, In-House systems not significantly inferior
