Innovation and design, when confron- ted from the perspective of a process defined as bottom-up, we sacrifice cla- rity and simplicity of a key concept for the sake of a solution conceptually more complex, solutions constructed from individual aspects of the problem to deal with. In the field of innovation mana- gement and process design (architec- tural, product, computer, management ...) is opposed (and complements) to a methodology called top-down where we establish, after a problem analysis, analysis, results the overall concept that dominates to the proposed solution, be a lighting master plan or design a chair. In a process of bottom-up design, the particular solutions are always being re-evaluated and put in relation to the other members of the system, and to develop it requires the participation of different approaches and disciplines and a constant and profound explora- tion of the problem and its context. The essence of the solution, that dominant concept of which we speak, appears (hopefully and achieves a simplicity that cities and their evolution, the festi- val presented initiatives and projects focused urban design solutions from this detail-oriented approach, to spe- cific solutions to challenges and social problems, and the usage and activation of public space to which architecture can give an answer.
