Ñ Users expect Ó Plastic UIs through a responsive design
Ñ Stakeholders Ó Find only partial support for design

Ñ Models are an abstract and simplified representation of a system
Ñ MDA aims at alleviating the cost of code production while improving its qualities
Ñ Context-‐‑awareness is a capability to identify and consider contextual information
Ñ Adaptation aims at providing users an application that is more suitable according to the context of use
Key concepts
SigDoc'ʹ2013 -‐‑ Greenville, NC -‐‑ 10/01/2013 8
Ñ H1) Stakeholders are aware of the importance and the benefits of considering: context-‐‑awareness, model-‐‑based approaches and adaptation.
Ñ H2) Stakeholders do not fully incorporate into their daily work practices: context-‐‑gathering, model-‐‑based approaches and adaptation.

Ñ …models are relevant and useful but the lack of "ʺeasy to use"ʺ applications, "ʺeasy to draw models"ʺ puts resistance for developers to use these tools
Ñ ... 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…

Ñ Models held in the cloud Ñ Graphic UI
Ó Forced directed layout Ó Drag-‐‑and-‐‑drop of model components
Ñ Constraint propagation Ó Abductive Reasoning

Discussion Ñ Stakeholders recognize the relevance and benefits of models Ó But they partially adopt them in the software development phases
Ñ The complexity and efforts needed to incorporate them is the main drawback
Ñ Only by facilitating and supporting its adoption through beoer tools, it may increase their usage
29
Ñ Quill benefits Ó Web-‐‑based application Ó Models hosted on the cloud Ó Flexible approaches to work Ó Collaboration among stakeholders of different expertise levels and domains
Ó Compliant with CRF
