static dynamic

Developer-centric

User-centric

Traditional SE

New SE Paradigm

Main Approaches

• Task-oriented Service Computing

– Enable high-level software design (in multiple abstractions) with primarily considering user tasks

– Support iterative and gradual development

– Improve reusability

– Enable application adaptability

– Enable service-privacy tradeoff

• Dynamic & Adaptive Software Engineering

– Improve correctness and context awareness

– Improve interoperability

– Support semi-automatic composition

– Enable end-user programming (mash-ups)
