Requirements definition that is an important work process for a project and may determine the success or failure of system development project tends to draw an ambiguous conclusion, which will lead directly to the failure of such a system construction. We think the destabilizing factors that introduce ambiguity into the requirements definition process and, as a result, cause requirements definition projects to fail are factors due to requirements definition methods, factors due to undefined implicit requirements, and factors due to interpersonal relationships among stakeholders. We will analyze requirements definition projects’ “destabilizing factors” that destabilize the requirements definition process and result in requirements definition failures as well as failure of IT System Construction (hereinafter referred to as ITSC) as a whole, then we will use fuzzy logic to model this. Additionally, using examples of actual ITSC requirements definition projects, we will apply our model to the situations of a project that concluded successfully and a project that ended in failure, then consider the cause and effect relationship between destabilizing factors and the success and failure of requirements definition projects.
