This deliverable is the second one of WP 2 and stands upon the user requirements to sketch the design of the interactions expected between the BD2Decide actors and the ICT environment. The work, which is presented in this deliverable, strongly relates to the user centric design process that the project follows in order to develop the BD2Decide components, in order to ensure that development is aligned to the user needs and the released software receives the acceptance of the stakeholder groups. As such, this deliverable establishes relationships with the work performed in WP 5 about the usability evaluation.
