6. Decision making
• Making decisions (two ways):
 Constraint satisfaction decisions (quantitative)
AK+MDD+NFRs
•
Constraints over properties of the elements of the
system
 Quality-oriented decisions (qualitative)
•
•
Knowledge of decisions
Relation between decisions and quality attributes
• We think that both ways can be used together
