Waterfall (predictive) model

The waterfall model, or aside of the software development environment commonly called predictive model, refers to a technical approach to plan and breakdown projects [1: pmi predictive]. Originally intended for software development, this method evolved and adopted to various scenarios including different project management styles. Today’s definition of the waterfall model refers to linear sequential planning of steps or phases, but over time various adjustments, extension and further developments to the original model have been made. In the context of project management, it is often referred to as the predictive or planned approach because of the high level of detailed and advanced planning for the complete project scope.
