How are these similar?

• Software
• Sausage
• Standards

You dont want to know how they are made!!!

MESA - MES Functional Model

• MESA is a not-for-profit trade association
• Founded in 1992 by the leading manufacturing
  execution system software vendors
• Identified 11 Functions of MES and contextual

Cost Reduction ScenarioArla Foods
Cost may be acceptable to larger production sites
Business Spec.
Cost must be driven substancially lower to match
the cost/benefit ratio of the many sites.

Costs of Specification and Configuration Present
the Greatest Opportunity for Decreasing Overall
Costs. Reduced life-cycle costs in maintaining
solutions on XX sites !!

How Many Standards

• To make this room functional?
• To make manufacturing operations functional?
• Want if we only had one manufacturing standard?
