Abstract:
The requirements change always occurs during the process of software development. While the changes lead to the quality improvement of software products, they also bring impacts and risks to many factors in another dimension, in particularly, the requirement changes which has been analyzed in the earlier states of software development projects. After software development projects have been started for a while and the requirements change is proposed for some reasons, the project is inevitably affected by those changes. Therefore, to be notified beforehand of possible risks and impacts, which might occur after changing requirements, is necessary. One reason is that if the project manager has been notified and be aware of those risks and impacts, the manager will be exposed to more choices and decisions whether they will change the requirement according to the proposal or find different solutions once there is too much risk on the developing project. This research proposed the concept and model of the risk warning when a requirement changes that link to the requirements analysis data, recorded by the project manager. To assess the risk assessment and the severity of possible impacts that might affect to software project. However, the key factors which are taken into consideration in this research are: the change set, the risk set, the relationship between each factors and the relative weight of each factor in the form of a matrix of relationships. These factors are calculated to determine the impact level and risk level in the form of the risk matrix and risk assessment in the overview of the project.
