Model-based Approaches
• Benefits extensively investigated in academia– lower development costs– faster time to market– higher usability levels– optimal use of the resources available
• How is it actually adopted among industrial partners?– No consensus about this

• Background
• Problem
• Survey
– Methodology

– Analysis
– Discussion
• Conclusion

Background
• Models are an abstract and simplified representation of a system– MDA aims at alleviating the cost of code production while
improving its qualities
• Context-awareness is a capability to identify and consider contextual information
• Adaptation aims at providing users an application that is more suitable according to the context of use
44
Problem
• These 3 concepts target at benefits for both end users and developers– But they may imply in additional costs for development
• Sottet (2009)– industry still remains code-centric
– models still fit in the contemplative category
• It is not clear how IT companies actually understand, adopt and consider– CAA and MDA
55
Survey
• Based on 2 main hypotheses
H1) Stakeholders are aware of the importance and the benefits of considering: context-awareness, model-based approaches and adaptation.
H2) Stakeholders do not fully incorporate into their daily work practices: context-gathering, model-based approaches and adaptation.

Models
Results
• Models Benefits
– Provide a common language and standards
– Facilitate reuse
– Generate systems that are more complete and have more qualities
– Provide help for• Communication
• Discussion
• Analysis
1818
Results
• Models Drawbacks
– Hard to customize, to adapt, and to maintain
– Lack support (or have incomplete support)
– Hard or slow to synchronize changes
– Require more expertise, efforts and time
1919
Remarks
• …models are relevant and useful but the lack of "easy to use" applications, "easy to draw models" puts resistance for developers to use these tools
• ... if the model-based approach is directly responsible for the generated code and any changes in the code automatically reflects in the model then it would be extremely relevant to have this kind of approach during the development…
2020
Remarks
• ...maintaining the docs and the code in a disjoint manner makes me waste some of the time [...] given that the coding sometimes needs to be changed to work.
• ... I'm not sure models could be used in our domain: UIs are very complex and uses custom widgets
2121
Discussion
• Most of the stakeholders seem to recognize the relevance and benefits of such practices
• Model-based CAA is not fully considered or just partially adopted in the software development phases
• The complexity and efforts needed to incorporate them is the main drawback
• Only by facilitating and supporting its adoption through better tools, it may increase their usage
2222
Conclusion
• To actually incorporate models into work practices, stakeholders need– Complete support
– Mature frameworks
– Standard tools
