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 is the integration of all enterprise operations and activities around a common corporate data repository.

It is the use of integrated systems and data communications coupled with new managerial philosophies.

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

POTANTIAL BENEFITS OF CIM• Improved customer service• Improved quality• Shorter time to market with new products• Shorter flow time• Shorter vendor lead time• Reduced inventory levels• Improved schedule performance• Greater flexibility and responsiveness• Improved competitiveness• Lower total cost• Shorter customer lead time• Increase in manufacturing productivity• Decrease in work-in process inventory

6



CAPABILITIES OF CIM• Responsiveness to rapid changes in market demand and

product modification.• Better use of materials, machinery and personnel.• Better control of production and management of the total

manufacturing operation.• Manufacturing high quality product at low cost

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.
