User-Centered Design
Strengths Limits
 Engagement of  Does not support
users traceability
 Concrete  Does not support
representation of abstraction
the domain  Coverage problem
 Stories prioritize

6. 6
The Common Meta-Model:
a lesson learned

7. 7
Ambiguity:
a different perspective

8. 8
The aim is to find under what
conditions our experience can
be generalizes: recipe
 Strengths/limits analysis
 Making the divides explicit
 Mutual learning

9. Slide 9
Strengths/limits analysis
 It
relies on the identification of strengths
and limits
 This
allows to define integration points to
create a beneficial dialogue
 It allows to preserve their strengths.

10. Slide 10
Making the divides explicit
Identifying barriers that may hinder the
dialogue between the two methods.
 Epistemological divides
 Linguistic and conceptual divides

11. Slide 11
Mutual learning
Mutual learning represent the crucial aspect to
mediate between the different epistemologies
and languages
 Definition of a shared dictionary of terms
 Collaborative negotiation of the definition of
terms in the dictionary which leads to discover
hidden relationships between terms
 Iteration with refinement until the agreement
