We have taken advantage of the phase 1 action to fully assess the technological feasibility, evaluate the market trends and determine the business potential of WATLY. The needs of different segments of end users and cus-tomers have been taken into account, which has led us to revise the concept presented in the phase 1 proposal in terms of final scale and features of the final system to be pursued. The risks involved in the different techno-logical areas involved, have been fully assessed and measures have been defined to minimize the potential risks derived from the use of cutting-edge technologies. We have fully assessed our operational capacity to complete the envisaged project and have secured external expertise where needed for the next phase. Based on market assessment results we have foreseen the sales for the different segments and developed a production plan that will allow us to cope with the expected demand. A roadmap for commercialization has been elaborated, includ-ing the development of an innovative business model that will allow us to reach all target segments, based on defining a strategy adapted to their needs.
