This large, complex nonprofit organization projected significant growth over a three-year period for key programs which would significantly impact infrastructure as well as require cultural changes. PDG was engaged in a collaborative business partnership with another consulting firm because of our expertise in organizational effectiveness (OE) to complete an 18 month project. Our approach to the OE work was iterative, interactive, and integrated as we focused on cultural changes, process design, job analysis, and organization structure. We used a facilitative and consultative approach as we worked with Executive Management, Senior Management, and staff. A significant portion of our work focused on core business processes for five separate program groups. The OE work resulted in significant enhancement and reengineering of core business processes, more efficient organization design, and stronger and more effective collaboration within division teams.
