Assessment
               3. Set an hypothesis-------------------------
Hypothesis
               4. Collect related information-------------  
Reference
               5. Design experiments---------------------- Study
               6. Support, reject or modify the hypothesis
               7. Design experiments---------------------- Study
               8. Validate the hypothesis, establish a theory.

The theory or the model has three important elements:
observable (detectable), measurable and repeatable.
