Improve

1. Process improvement model

   • Characterization
   • Control
   • Optimization

2. Objetives of experimental design

   • determine which variables x are most influential
   • Determine set of influential x that
     • y is near the nominal requirement
     • variability is small
     • the effects of the uncontrollable variables z are minimized

3. Results of experimental design

   • 1. Improved yield
     • 2. reduce variability
       • 3. Reduce development time
         • 4. Reduce overall costs

4. Process of Designing an Experiment

   • Recognition , problem objetives
     • Select response variables
       • select design factors
         • Choice experimental design
           • conduct experiment
             • statistical analysis of data
               • Conclusions and recommendations

5. don't use all resources in the first exp.

   • think and experiment sequentially
     • Don’t underestimate the logistical and other complexities
       • Successful experimentation requires process knowledge
