A starting point (1/2) : Our findings
 Perimeter is management applications
 Starting from scratch is useless
 Some tasks always need to be done
 Some questions always come around
 Development is more and more complicated
 Too many technologies in RIA applications (HTML5, JS, Java…)
 Increase in expertise level required
 Tighter learning curve
TVD-REN
39

2013 © Trivadis
A starting point (2/2) : Our goal
 Don’t lose any time on tasks without added value
 Solve technical problems “out of the box”
 Be more productive
 Increase quality and maintainability
 “Focus on the business”
TVD-REN

Client Side RIA : a good approach?
 Huge work load on the browser side
 An important technology stack
 HTML / Javascript / Client side technology / Libraries…
 Requires a high level of experience and diversity from the development team
 Impact on the learning curve
 Client side is purely Javascript
 Weak Typing
 Lack of object model
 No specific development tool
 Quality and maintainability challenge
 Often leads to spaghetti code
