6
Problem: adaptation rules are static
Adaptation rules are implemented according to a predefined and static set of standards, guidelines, and recommendations
Hardly re-adaptableBarely impossible to updateHighly expensive (redevelopment, time, human resources)
7
Problem: static rules prevent adaptation
• Dissatisfaction• Frustration• Discouragement• Loss of motivation• …

Solution: involve the end-user in the user interface development
Throughout the system life-cycle From the early stages of the system life-cycleStarting from the user interface definition

(1) Executing pre-existed adaptation rules, serving as a training set to (2) detect a pattern of user behavior throughout his feedbacks. Besides, (3) coming up with statistics and (promote/demote) ranking for the Learner Rule Engine (RLE).
