Definition of CIM by the Computer and Automation Systems Association of the Society of manufacturing Engineers (CASA/SME):
“CIM is the integration of the total manufacturing enterprise through the use of integrated systems and data communications coupled with new managerial philosophies that improve organizational and personnel efficiency.” 2

CIM Objectives• Simplify production processes, product designs, and factory
organization as a vital foundation to automation and integration• Automate production processes and the business functions that
support them with computers, machines, and robots• Integrate all production and support processes using computer
networks, cross-functional business software, and other information technologies

CIM Systems• Computer-aided manufacturing (CAM) - automate the production
process• Manufacturing execution systems (MES) – performance monitoring
information systems for factory floor operations• Process Control – control ongoing physical processes• Machine Control – controls the actions of machines 10

LEAN MANUFACTURING• Lean manufacturing is a philosophy that considers the
expenditure of resources other than the direct creation of value for the end customer to be wasteful.
• Thus its targeted for elimination.
• Working from the perspective of the client who consumes a product or service.

Principles of Lean:1. Eliminate Waste
2. Build Quality In3. Create Knowledge4. Defer Commitment5. Deliver Fast6. Optimize the Whole

AGILE MANUFACTURING• Agile manufacturing is a term applied to an organization that
has created the processes, tools, and training to enable it to respond quickly to customer needs and market changes while still controlling costs and quality.
• Agile manufacturing is seen as the next step after Lean manufacturing in the evolution of production methodology.

Principles of Agile:1. Highest priority is customer satisfaction
2. Welcome changing requirements3. Frequent delivery of software4. Business people & developers cooperating daily5. Build projects around motivated people6. Face-to-face conversation is best7. Progress measured by working software8. Sustainable development pace9. Continuous attention to technical excellence10. Simplicity11. Self-organizing teams12. Regular reflection & adaptation

SIMILARITIESBoth ultimately focused on increasing business sustainability
in the high-cost manufacturing sector.Both are answers to challenges faced by historical
manufacturers.Both provide opportunities for smaller players to compete
with larger, entrenched competitorsBoth concepts rely heavily on statistical analysis, computerized
information systems and open communication between internal and external stakeholders.
