Most change management programs and PMO struggle to deliver key metrics to senior management because of poor traction with operating and senior management.
To make a metrics program successful, the 1 or 2 (at most) reports should be branded with a name. Branding and retaining the key metrics into a report say Q25 or T20 or 9box , enables recall and drives continuity to a changing/improving set of metrics.
Further, this can also be incorporated into training programs / presentations at all levels to ensure importance and recall. A generic non-branded report such as a project report can easily be abused / modified and mis-understood diluting the needs of project reporting.
