Planning phase analysis is typically a low-detail analysis applied to projects. Per the HCM, planning phase analyses are “directed toward broad issues such as initial complication identification, long-range analyses, and regional and statewide performance monitoring.” While planning phase analysis is often applied to high-level projects and large areas, it could also be applied to specific locations and projects that use many data inputs.
