| Nowadays, the software projects have the features of short development cycle, rapid changing of user requirements and using new technologies. Therefore, the software development teams have to face the risk of missing the project deadline, having trouble adapting to clients’changing requirements and having defects in software applications. Using traditional software development methodologies fails to be applied in the development of CIQ (Inspection&Quarantine of PRC) information systems. The reasons are listed as follows. First, it spends too much time in the software developing life cycle, so that it cannot meet the business requirements. For the second reason, system cannot adapt to the change of business requirements. The last reason is the software quality is poor. To solve those issues mentioned above, a new software development methodology needs to be implemented. As a result, Agile comes on the scene.
