What is Manufacturing System
Design?
 Manufacturing system design is NOT just …
 Factory floor improvements
 Kaizen activities
 Changes within the four walls
 Waste elimination
 Manufacturing system design IS the above plus …
 A selection of a layout that meets system demands (outputs)
 Development of an operational policy for decision making
 Selection of the right process technology
 Make-buy decisions
 Organizational structure design and interaction methods

What is Manufacturing Strategy?
A “game plan” for the manufacturing organization to
keep itself aligned with the Corporate strategy
It consists of :
 Long term objectives
 Strategies
 Programs
 Initiatives
To help the business build and maintain a
competitive advantage for future success

Why Have a Strategy?
 Assures decisions based on long term success of the
enterprise
 Aligns manufacturing with business and corporate
strategies
 Creates an awareness of competition
 Assures long term product, capability and process
differentiation from competitors
 Provides for clear communication between management
levels
 Focuses improvement activities on long-term success
PROVIDES A BASIS FOR FUTURE SUCCESS

Best Life Cycle Cost
Acquisition Cost + Direct Operating Cost +
Maintenance Cost - Scrap
Acquisition = Development Cost + Manufacturing
Cost
Direct Operating Cost = f(performance)
Maintenance = f(External Quality) + Ease of
maintenance
Scrap Value = f(reliability, maintainability,
customer support)
