A comparison between agile(incremental) , non agile(predictive) and DevOps methods in global software development

Nowadays more and more software engineering related projects are being carried out using a global software development model in order to take advantage of the global talent pool at a cheaper cost and deliver a product in a short period of time. To this end, project managers are trying to adopt different methods to achieve their goals. Incremental, predictive and DevOps methodologies have been proven to deliver great success but, in distributed development model, some challenges as well. The aim of this study is to present a comparison between the predictive, which is the pioneer method and “father” of all kinds of project management methodologies, incremental, which emerged as an alternative to situations where traditional plan-driven methods are insufficient and have gained a very important place today, and DevOps ,a method that incorporates agile principles and practices but also emphasises improved collaboration between development and operation teams. This study intends to identify the project management characteristics that are associated with greater project success in global software development settings.
