Since the 2000s, a number of important architectural and urban legislation have been enacted and revised. Due to these changes, numerous related policies were derived and projects implemented nationwide. However, in the process of implementation, a number of common problems have been identified including a supplier-centered project monitoring and feedback system, a lack of distinctive charactor in each local project, and lack of participation from user groups. In the United States and United Kingdom, crowdsourcing has been utilized in public projects to tackle similar issues. ‘Crowdsourcing’ is a term first coined by Jeff Howe in the June 2006 issue of Wired magazine which combines the words ‘crowd’ and ‘outsourcing.’ This refers to the act of seeking problem identification and solutions from the non-specialist general population. Central and local governments, as well as NGOs and private sector companies nowadays are utilizing online platforms to obtain ideas from local residents regarding architectural and urban policy projects. Crowdsourcing is used to identify architectural and urban issues within the local community, develop local policy projects, expand community participation, and evaluate ongoing projects through their many stages of development. Korea has an apt environment for utilizing crowdsourcing whereby a first-rate ICT infrastructure can be installed with more than 93% of the population being a smartphone user.

The purpose of this study is to explore the possibilities for crowdsourcing as a means tomonitor policy and architectural projects. Toward this goal, the study developed a prototype crowdsourcing-based project monitoring system and applied it to learn the possibilities andlimitations of such a system.
