Southern Water, a UK water utility serving 2.5 million customers, replaced ad-hoc project management with a centralized portfolio approach. By loading all initiatives into Planview PPM Pro, leadership reduced active work from 450 to 200 items, established programme-to-project hierarchies, and cut weekly reporting time from two days to one hour. The utility now tracks milestones, resource capacity, and strategic alignment in real time while preparing to expand into enterprise portfolio planning.
