and adding value. (Granja et al 2011; Guadanhim, Hirota and Leal 2011; Aragão 2014). The design
process of this work is a partial application of TC.
Particularly in the PMCMV, the same contractor can develop the housing project having control
over the constructive variables, productivity and cost data. The high level of competition in this
program may trigger a search for optimization of the construction costs and competitive advantages, allowing the customer to make choices that best suit LIH needs. Government funding and
the offer of significant subsidies have attracted big contractor companies to the program. The use
of prefabricated parts is being singled out as a trend for the sector. The environment of continuous product improvement focused on the consumer, in the context of a meritorious competition
for the supply of social housing, can find in the TC principles the basis for promoting this new
scenario. (Granja et al 2011).

3. Methodology
3.1 Strategy, characterization of the team, partnerships, workshops
The strategy adopted to implement a collaborative design process was to hold weekly work
meetings and workshops. The coordination was under the responsibility of researchers, involving
teachers and graduate students. The work was conducted by the interaction of specific research
groups, organized according to the specialties of each researcher (Table 2). During the design
process, there was a collaboration of invited professionals from different specialties who work in
the social housing sector, including builders, social workers, engineers, architects and suppliers.
3.2 Customer requirements
Many attempts to understand and / or prescribe the design process in architecture were developed mainly from the 1960’s. The review of such studies shows the difficulties and the complexity of the designing task. Despite the development of numerous strategies and methods, such
research is permeated by the recognition that the design problems have not only one single or
optimal solution; just the opposite, the partial solutions of design problems create new problems,
a continuous spiral that will be interrupted at any given time either by the understanding that
solution is acceptable or even by the depletion of time. Such complex problems were defined by
Herbert Simon as wicked problems - treacherous problems, ill-defined, incomplete, contradictory
and changing requirements - for which finding appropriate solutions is very difficult, because
every solution generates a new problem (Bayazit 2004).
Admitting the lack of full understanding of the problem to be solved, methodologies involving
client/customer participation are valid alternatives to reduce the uncertainties (Kowaltowski et al,
2006). The PMCMV establishes a very detailed basic architectural program with minimum requirements of habitability. However, in order to improve the living quality, rather than simply answer
the program, the design process should reevaluate it, taking into account the future resident
needs and desires.
