In the age of fast evolution, software development project must accept many challenges of unpredicted requirements change and new technology environment. Software development processes should have adjustable and extendable features to meet the multifaceted needs of the users. Iterative and Incremental Development (IID) is a practical approach to overcome the various challenges of software development.However, continuous testing and building new versions need to spend more time and human resources that is a major obstacle of IID. The other, the iterative operations must have a sound communication skills. Lack of standard version control and intercommunication manner often lead to failure of software project. High quality Continuous Integration (CI) environment can effectively make up the defects of IID.
