This master thesis investigates how an Agile User Centered approach can be used when designing and implementing the frontend for a web-based on-demand video streaming platform. Agile and User Experience (UX) are currently two very popular concepts that are frequently discussed in the software development community. Recently there have been a lot of discussions about how to combine Agile development methodologies and UX activities, and it has proven to be a difficult task in practice. This Master Thesis aims at solving this issue by researching methodologies that take both the Agile aspect as well as UX in consideration. Dual-track Scrum, an Agile/User Centered methodology considering UX, was used as development methodology and throughout the development process it was investigated how this methodology, as well as adding UX activities, affected the UX of the streaming platform. The conclusion from this thesis is that even though the combination of Agile and User Centered processes is difficult, it can be achieved with good results. The thesis presents guidelines for how to successfully combine the two processes as well as what the most important UX activities are and how they can be used in an Agile development project. The thesis also concludes that using a frontend framework, development tools and HTML5 video is very useful for developing the frontend for the streaming platform.

The thesis aims to develop a method for extending the language platform Storm with a Java frontend.The project was conducted using an Action Research methodology and highlights triumphs andchallenges. Despite the significant overhead related to note generation and problem statementformulation, this methodology proved beneficial in identifying problems and providing the framework tosolve them. The first research question (RQ.1) evaluates to what extent the language platform Storm is suitable forimplementing the object oriented language Java. Using Storm, only a BNF and a specification for three-address code instructions are needed. Despite encountering difficulties during the implementation, theplatform offers tools that allow comprehensive customization of the new language's intended behaviorand functionality. The second research question (RQ.2) explores a suitable method for implementing a new language inStorm. It is suggested to first implement a foundational structure comprising of statements, blocks,scope handling and variable declarations. From this foundation, new functionalities can be graduallyintroduced and tested by connecting them to the appropriate location in the structure. When allfunctionality is added and tested a refactoring step can take place to modify the BNF if needed.
