1. WP4 – Software Refinement

2. Highlights Participants – i2CAT, HEAnet, NORDUnet, UNI-C, Uessex, Telefonica I+D, Trinity College of Dublin. Objective This activity will focus on the analysis of the user requirements (from NRENs and virtual research communities) and implement them. The implementation phase will include a subtask to solve the bugs that later can be found when the service will be deployed in an operational environment and used by the NRENs and the virtual research communities. T4.1 Requirements Analysis (3 Months) Study end user scenarios. Gather requirements via use cases. Get together workshop to close an initial roadmap. T4.2 Software Development (14 Months)

3. Tasks T4.1 Requirements Analysis (3 Months) Study end user scenarios. NRENs and virtual research communities. Gather requirements via Use Cases. Get together workshop to close an initial roadmap. T4.2 Software Development (14 Months) Early and frequent deployment. Continuous deployment on user test beds. Early and frequent feedback. Continuous evaluation of the feature releases. Continuous replanning of feature priorities. releases
