Abstract
In order to communicate each other we need both a system and contexts. Generally a system is called language and contexts are a common sense with a culture. If there is an absence of one of them it is impossible to understand each other. The concept of UPDP(User participating Design Process) is very similar to a communication. There must need both a system(formal tools) and a process to make consensus. Even though we already have two systems(KEBDI and PDAT) being developed by government affiliated research institutes these have not intimately related to a process to make consensus so far. In this respect the UPDP with using DQIfS of U.K. for a remodelling of Noryangjin elementary school(2013) is the most valuable because it is the first trying to communicate between laymen and professionals by menas both of a qualified system and of facilitations which have been developed from Namhansan UPDP(2001) in korea. The paper shows the process of UPDP including how to organise the members, detailed facilitation methods and the result of DQIfS analysis in U.K. Above all for the successful result the most important thing is the intimate relationship between the tool and facilitations at the beginning and user's will to build up.
